Reference Class Hi-Fi Wireless Earbuds, Dolby Atmos, Head Tracking, Adaptive Noise Cancelling, 3 Device Multipoint, 10-hr Battery, Wireless Charging, in Ear Headphones - EAH-AZ100-K (Black)

Amazing sound! Best I've ever heard from a set of earbuds. I moved up from a cheap pair with no ANC, and the difference in quality is immensely noticeable. I spent WEEKS mulling over which brand and model to buy. I'm a casual audiophile, so I wanted incredible sound while also factoring in comfort, features, battery life, and user reviews. I narrowed down my options to this and the B&W Pi8, which I knew would also be a good choice. The reason I chose this over the Pi8 is use reviews. Nobody complains about the sound quality of the Pi8, but the overall user experience for the AZ100 was higher, so that swayed my decision. Let me tell you, brother, I am more than happy with my choice! Here is what I love about this product: Sound quality: Listening to Ultra HD music with LDAC enabled is a religious experience. I'm listening to some music I've heard a LOT before, but it's an all-new experience for me. It's like falling madly in love with the same person all over again! I prefer stereo mode, but using positional audio with Dolby Atmos and head tracking is a nice option, and I've found it to be really great on certain tracks, especially those specifically designed with 360 audio in mind. Comfort: My old, cheap earbuds were pretty good, for the price, but I had to fiddle with them a lot to get to stay in and feel okay. Once you go through the guide to figure out what size tips to use, these earbuds "lock in" better and feel great. It's like I forget they are even there. The longest I've ever used them so far is two hours straight, and I felt zero discomfort. Noise cancelling: Impressive! I've never experienced ANC before, so I cannot compare it to Sony or other brands, but this is a game-changer for me. I live in a very quiet house in an extremely quiet neighborhood in the middle of nowhere, and I thought ANC would be overkill at home, but I was wrong. It's crazy how much ambient noise there is that you don't even think about. When I turned ANC on at home, I think I audibly gasped! I had never "heard" so much silence before! 😂 When I started listening to music, it was something special, and I knew I had made the right choice to spend good money on a premium product. Customization: The app lets you adjust equalizer settings to your liking, which is a must for me. I know this is standard for premium earbuds, but my last one only had presets, and no matter what I did, the bass was always too much, even with the "Bass reducer" setting. I don't understand the appeal of the power frequencies overpowering everything... but I digress. Beyond the equalizer adjustment, you also have so much control over the noise cancelling settings. When I'm at work, I can not only turn off ANC altogether, but I can adjust how much of the outside world is boosted. I have to be attentive to my coworkers and notifications on my computer, so it's amazing to be able to hear everything so clearly and still be able to hear the music in such amazing detail. I cannot say anything negative about this. $300 is a lot to spend on earbuds, so that may be one aspect of this that some would find as a negative, but this is probably the last set of earbuds I'll buy for a VERY long time, so that's one way I justify the price. The other is that you really get what you pay for here. Multiple professional reviewers list this as the best overall option for 2025, and they have done that with good reason. If you are on the fence like I was, and you can afford the premium price tag, I think you'll be beyond satisfied with your purchase.

I bought these for the rave reviews I'd read about the exceptional sound for music playback - which is absolutely incredible - but a surprise feature is the call quality, in terms of what the microphones can pickup: and what these block out. With the "AI" feature turned on, it eliminates background noise on your side. It's so good it's wild. Let's talk about the call quality first. This is a game changer for me, as I'm on MS Teams calls throughout the day - and I have young kids at home as well, plus I will sometimes I have to speak on a call and I'm in the car or not quite in the house and it's windy out. Being on the go is not really something you want to convey in a work call. I picked these up before heading to Disneyland the week of Thanksgiving with the kiddos. While there, my sister called. There were no less than one million people there at that time, many talking near me, music in the background, all this sound. She asked where I was. I said, "Disneyland." She was surprised because she couldn't hear anything in the background. So I looked into it and found out the "AI" voice call setting was flipped on by default. You can actually test this yourself in the accompanying Technics phone app. In the test, it'll continuously record your voice and play it back on a few-second delay. With the AI enhancement OFF, it's great at capturing sound around you like typical earbuds. With it on, it's ultra clear and only your voice. I mean, it's so good I've been telling everyone I know about these. Today I was sitting next to my 3YO, 6" away, who was actively screaming at the 5YO, 3' away. Whoever I'm talking to *cannot hear this*!! I've even been at a DIY car wash with the sprayer in my hand, full blast, on a windy day. While I didn't hear that audio myself, the person I called said they couldn't really hear anything in the background. I seriously cannot believe how good these are. I'm so confident in how well they block out background sound that I will do dishes while I'm unmuted on small group work call. (For much larger group calls, I don't need to experiment: I'll be muted in Teams, turn off my microphone on my phone, and mute these as well.) One feature I haven't tried yet: there's even an AI feature to block background noise on the other end of the call, too. So if your friend is in a noise place, it can block *their* background noise for you. I haven't encountered this scenario yet but I bet it works great. Audio quality is outstanding. There's a built-in EQ, plus your phone's as well, of course. Between the two - and the Dolby Atmos on my Samsung - the bass is surprisingly deep, mid and highs clear, and they have a great sound stage. I listed to music from Qobuz (CD quality at minimum) and very much appreciate HiFi audio. It's fun to listen to music all over again on these earbuds. There's some kind of Dolby Atmos feature built into these where the sound changes if you move your head around. I haven't played with that yet. You also have options to block out background noise when listening to audio (a few ANC settings) and the pass-through feature, too, which lets in background sound and has a voice focus setting that works great. What else: they connect to multiple sources, are comfortable to wear (I can have them in for a few hours straight), and I haven't had issues with battery life despite wearing them for calls much of the day. I'm still getting used to the button taps on the right and left earbuds (one tap for this, long tap for another feature) but these are customizable, too. I would say the one part I'm getting used to is the size. Maybe it's the drivers that make them a little bit bigger. I'm coming from the Jabra Elite 7 Pro's and also the Anker Soundcore sleep buds (which are much smaller and flush with your ear, of course) - so these feel a touch larger. But for the top-notch audio quality and amazing ability to block my background noise for call recipients, it's not an issue. These were on sale before Thanksgiving - maybe check the price history - but for the features here and my new ability to actively move around without concern on work or personal calls, the value is unsurpassed. I absolutely love these and would encourage you to buy them if you want amazing earbuds for music and voice calls.

I bought this because my over-the-ear cans were too bulky when I was out and about town, and my other set of earbuds did not cancel ambient noise on my side when I was on calls. The over-the-ears I will be comparing them to are my Sennheiser BT450s, and my Bose NC700, and the TWS in my comparison are my B&W Pi8's, though I will mention my experience with Sony WF1000M3 that I used to own and a recent LG TWS. What I discovered in half a week of using my Technics AZ100's is that they are surprisingly good earbuds for a reason I didn't consider previously. Drivers and EQ I have experienced with a few headphones, TWS or otherwise, a hiss. The headphones would cancel noise well enough when there is noise, but when there isn't or during quiet moments in a video, there would be a hiss. The AZ100 doesn't have a hiss that I have been able to detect. Above that, the app offers the most precise EQ of all of my devices. Most just offer three frequency ranges, Bass, Mid, and Highs. This app offers seven, eight? The SoundGuys website commented the factory tuning is clumsy and bass heavy. If you take the time with these equalizers, you can get closer to the ideal EQ settings than if you only had three bars to adjust. I would say these drivers produce sound that is equal to any Sennheiser I have used. Out of the box, they sound like my Bose NC700 with punchier percussions -- which is really nice. These are more capable drivers than Sony's and LG's in-ears. I haven't gotten them to sound as good as my BW Pi8, but I'm being picky and the Pi8 are 33% more expensive. Call Quality The only weakness of my Pi8 is that it lets in too much ambient noise when I'm on a call. One time, I was doing the dishes and the AC was blowing, and my mother, who is hard of hearing, was able to call out every one of my activities. I guess it is a way to make the other party feel like they're right there with you, but I don't think that's what most people mean when they say that. I repeated the same test with the AZ100 and my mother could not tell when I turned on the tap or stopped it, when the AC kicked in or stopped, or when I was next to my audible dishwasher. The complaint from mom was that my voice sounded robotic and occasionally I'd sound farther away. The other party on the other end was easy to hear for me. This was not anything that was a weakness of any of my earphones, but I believe with the AZ100, their voice is processed via the EQ. ANC. The Pi8's ANC design is quite nice in that, around the office or at a restaurant, it lets in some of the ambient sound but doesn't let it interfere with what I'm listening to. I hear my environment, so I don't miss my colleague asking for my attention or my server approaching. I hear things but I don't, if that makes sense. The reason I mention that is that the AZ100 doesn't seem to be so well tuned in that regard. At a restaurant playing loud music, it is fainter, but my podcast is still competing against it. At the same time, in the office, faint sounds drop off into near silence but louder sounds don't seem to be affected. At its best, the AZ100 perform as well as my Bose NC700 or the Sony WF1000M3, but I feel this isn't going to be one of its best traits. It's still very good, mind you -- I'm pitting it against class leading cans of the last few years after all -- but if this is something that is very important to you above all else, then it's probably not the best TWS for you. Portability and Touch Controls The case is tiny. I alternate between these and my Pi8 on the weekdays. I carry both in my pocket. This case is smaller, lighter. I did not perform a drop test, because they're new and they're expensive. I did perform drop tests by accident on my Pi8's. Both the case and buds were dropped from hip height and ear height onto tile with no apparent scuffs to the plastic shell or the internal electronics. The touch controls of the AZ100 are more responsive, it felt. The Surprise The AZ100 went in a different direction than the other buds in one major way. They are extremely light. They are lighter than any of the buds I have ever worn. This has a surprising effect. The buds stay very stable in the ear. I can turn my head quickly, and they won't go flying out. I can walk around, and there isn't even the slightest bit of movement. (In my review of the Sony WF1000M3, I commented that they were so heavy and jutted out so much that once, when I was crossing a street and hurried just a little at the end, the buds fell and I was lucky enough to catch them.) Something like that probably won't happen with these, though, once again, I won't be repeating that experiment. These are a compelling entry into the TWS field. If these were released the same time as the WF1000M3, these are probably better in every category except for the ANC tunings. These are better than the LGs, but the LG's offer a UV self-cleaning feature. And the AZ100 can compete directly against many of the higher-end over-the-ear headphones.

I bought these to replace my Sony WF1000X3's (yes, now two version old) whose charge controller died after 5 years. The Technics offer a notable improvement in sound quality particularly in instrument separation. The bass feels entirely different from the Sony's with the Technics feeling as though the bass were in my head rather than near it. Try the different equalizer settings in the app. These sound better somewhere between the Dynamic and Treble+ settings. Bluetooth connects quickly; within 2-3 seconds of taking it out of the case; a big improvement over the Sony's 15-20 seconds. While the Technics is often described as being not as good as Sony's latest offerings, I expect it to be as good or better than the XM3's. It isn't. It's good, but it has two limitations. The first is that it's effectiveness is driven greatly by the quality of the seal from the eartips, and it's challenging to get a good seal. They need to be pushed in your ear solidly. I recommend going with a smaller eartip than you would expect. The stock eartips work pretty well. I've tried memory foam tips which were amazing on the Sony's, but whose comfort is mediocre due to Technic's mysterious decision to make the ear bud speakers oval and cumbersome to replace. The silicone SpinFit tips provide the best balance of comfort and isolation. Even with a good seal, the ANC isn't the vault-door shutting finality of the Sony's. High pitched noises enter pretty easily with some sounds, like plates being clanked together seem to bypass the ANC entirely. Right now I have Indigo Girls playing on the stereo and even with these earbuds solidly in my ear, the lyrics are understandable even though the music is inaudible. The app's ANC fine tuning does almost nothing to improve this. The stock configuration of the earbuds will result in a noticeable delay between audio and video. This can be remedied by turning on the LDAC codec in the app will resolve this, but at the cost of multi-device connectivity and battery life. Battery life is excellent so far even with LDAC turned. I have yet to wear them for more than 3 hours continuously at which point they were at 56%. The case brought them back to full charge in 10 minutes. We'll see how these hold up long-term; hopefully longer than the 5 years the Sony XM3's survived, especially since the Sony's really died after 3 years, but at least it was possible to change the batteries. Modern earbuds have put an end to that.

Absolutely fantastic quality. The battery lasts all day, and the case means I only have to charge them every 2-3 days with how often I’m using them. The range of sizes for the tips and the guide for fit testing was also very useful. They don’t hurt my ears at all which is an issue I’ve had with other brands, and they stay put even when I’m driving the tractor around on rough terrain all day. The sound quality, noise cancelling, and sound adjustability was also a major plus. You have no idea how amazing it is to be able to drive a tractor and the noise goes to a mere rumble rather than a roar. In a car there’s almost zero noise whatsoever. I could go on and on about how much I love these. Will definitely buy from this company again in the future.

I have EAH-AZ8s and using them since it was released. But as many people had, I have the issue of lower sound from the right bud. I live in Turkey and there is no service here to fix them. So, after a long searching of reviews I decided to buy the new one EAH-AZ100s. Also AI confirms that they arethe best for now. As they said in most of the reviews case is bad (very flimsy) compared to 80's. There is almost no difference in the sound for me in a plus way. It was already extraordinary. 100's fit deeper and much better in the ear Canale since they are smaller. It is literally impossible to hold them, take out from the case and plug in your ear because of the round shape. As plus It has 2 more rows and 3 custom availability for the equalizer in the app. I have the champagne color which is great. I see no reason to buy them EXCEPT the small form factor (smaller case, smaller buds). AZ80s were bulkier but I may say that sound can be even better on them. Also I think they are more comfortable. So, I still recommend EAH-AZ80s over 100s. They both are fantastic though. Update : After discovering LE Audio option, these buds made more sense. Almost zero latency in videos and especially the computer games. They connect to pc ( in my case through a bluetooth dongle: Asus USB-540 specifically to support LE Audio) quite easily. You have to choose the correct option with double earbud icon, not the headset with a mic. Also you should download proper drivers for the BT Dongle and enable LE Audio option from Windows (ask AI if you can't do it) . The trade off is; all the other options are cancelled as Spatial Audio, Multi connection, LDAC codec. Indeed you have to first connect to your phone and change the settins to LE version over the Classic option in the Technics app. Re-pair the buds to the phone, then you can pair and connect them to the pc. Yes you loose the options but you gain LC3 codec if your phone supports it. This codec is better then SBC and AAC but lower then LDAC (that you can't generally take advantage of since phone apps like Spotify and YouTube can't stream that high and if you are not a audiophile). I can say thet sound better now with this codec. So I sacrificed from the other options and each time I connect to a device, first I have to disconnect from the previous one. But sound is very good and zero latency is a bliss. I hope this helps someone whoever is searching for a real review in details, unlike the commercial reviews but a real USER.

I'll try to keep this short as I can go on all day about audio stuff. This fits well and is comfortable but I have to put the larger size cushion on to keep from slipping out of the ear. The sound quality is good but don't expect B&O quality sound. The noise cancelling is pretty good, much better than B&O but not as good as Bose. I don't really like the sound traveling from one side of your head to the other when you turn your head. The main reason I bought these was for the play time before a recharge and it is great there. I get easily 8 hrs + much better than my B&O. Well worth the money just for that as long as your ok with decent sound vice superior sound.

Update: 5 stars! The voice isolation on calls is out of this world. I can chew a crunchy bag of Gardetto's without the person I'm talking to hearing any of it. Airport announcements? I was asked if I made it into the airport at all in the middle of an announcement. Fitment: They stay put in my ears and, for once, the recommended sizes work as expected. They handled running, weightlifting (laying on a bench, decline, and repetitive up/down movements) Connectivity: Rapid. The moment they're powered up, both connect. Gone are the inconsistencies experienced especially with Sony's effort. Comfort: This is tricky but a necessary method for my ears. When I set them in, they must sit flat against my ear. Otherwise, the inner top edge does irritate me after prolonged use. Fortunately this not only helps with comfort, but vastly improves the seal. I can smile without ANC notably reducing. Sound: I don't think they're loud enough despite my best effort to improve this, but I'm pretty sure louder can be damaging. ANC: It's just okay. These are begging for foam tips but for the sake of comfort, I'll stick with what these can do. ---------- Direct comparison to the King of the earbuds hill for ANC and voice isolation on calls. I'll go through every aspect. As far as I'm concerned, these are the only true bud-for-bud competition for the WF-1000XM5. Ease of use - while the Sony app is arguely more GUI based, the Panasonic/Technics effort is effective after you get past the overwhelming amount of text. Initial iss (first few attempts) are easier on the Sony. After that, you find odd menu placement on Sony's whereas the Technics menus have some redundancy to find items you may miss elsewhere. Most importantly, it offers a level of customization that Sony doesn't touch. Volume Control - Both are fine. Continuous taps, double and triple taps, etc. they all work. Does it work as well as the crown on my smartwatch? No. Does it bother me? Also no. Battery life - this is close, but the Sony's edge out the AZ100s with full ANC. It's a tie in my book but let's call a spade a spade; they're within 1/2hr of one another in favor of the Sony buds. Durability - Both have the same resistance. I'd say it's fine. I can see them taking a drop and blowing out of the case. Don't drop the baby! Value - sub-$250? I think they're worth it. There are some fatal flaws that other buds succumbed. Not these. They are well-rounded, albeit not incredible ar everything. Now that I knocked out some high level pointl, let's talk about what matters to me on a broader comparison of brands. Comparison note: Bose QC Buds V2 (QC2), LinkBuds S (LBS), WF-1000XM5 (XM5), OnePlus Buds Pro 3 (BP3), Google Buds Pro 2 (GB2), and the AZ100 (AZ1) Noise canceling - Top? XM5. The AZ1 trail most of the other earbuds. Too much high pitched noise comes in and the ANC initial adjustment process makes you second guess what you're doing. My order of ANC would be XM5, GB2, LBS, BP3, AZ1, and QC2 in last. The QC2 have a bug with pressure stabilization. Shut a car door and the feedback is atrocious. I've tried 2 sets with the same results. Voice isolation on calls (own voice) - This is easily a win doe the XM5 followed by the AZ1, GB2, QC2, LBS and BP3. The XM5 bone conduction mics and the processing power behind it makes it impossibly effect in certain scenarios. Like, you can chew an ice cube and the person you're talking to won't hear it. The GB2 and AZ1 are beam forming, but the AZ1 voice AI does seem to edge out Google's measures. The QC2 didn't bother cutting out wind noise when a car window is open. Same with the BP3. LBS severely clip your voice in most cases. To be fair, voice distortion seems to be inevitable with all calls in loud environments. Isolation of background noises is the emphasis of my point. Music - I feel like it's the QC2 for the win. Not on overall volume, but clarity and bands. The AZ1 and XM5 sound similar to me. GB2 and LBS are also similar. BP3 were my least favorite here with the unusually "rich" sound. Definitely not something I'd consider "reference". If you like that, they lean towards more of a punchy sound. It's not as rich, but it's definitely that out of the box. Spatial sound - QC2 sounds cool. Neither the LBS or XM5 were tested due to accessibility limitations. AZ1 was okay, but it makes it sound distant. The rest weren't notable. I have to say, this feature isn't one I leave enabled. It's weird that music moves around my head. Not my cup of tea. Customization - AZ1 are the most customizable in every way. The rest are a tie as far as I'm concerned. Fitment - Every single app misleads me on which tip works best. Every single bud has something I don't inherently like about it. Nearly all except 2 have the same issue and, you probably guessed it, comes down to the buds not staying in my ear. The LBS and AZ1 are the best at staying put. I think it's a matter of weight and these are both fairly light products. The GB2 come close to perfect but that wingtip makes my ear sore where it's pressing. The seal is a problem when I move around or workout. XM5 are massive and heavy. Even that foam tip doesn't stand a chance and wiggling them around constantly hits the capacitive buttons. QC2 are just weird. They feel like they're floating in your ear but I never get a good seal, which plays into the ANC feedback that literally will damage your ear. BP3 just fall out. They are effectively laying in my ear. Do I recommend the AZ100 aka AZ1? ABSOLUTELY! My day is spent on calls at work, talking to family, and workouts. These are the winning blend of everything. A daily driver or Every Day Carry (EDC) if you will. If the XM5 are near the sale price of the AZ100, I'd consider you trying them out. They are heavy and bulky but it's an experience worth knowing. The QC2 may work better for smaller ears as well as the GB2 and BP3, but I wouldn't recommend the last one at all. The instead, look for the LinkBuds S for that budget buy. I hope this helps. It was a brutal adventure finding a device that works for me. Cheers on your journey and kudos to the Technics team for making such a well balanced product!
