Sardonyx SX-918 Wireless Headphones, Best Bluetooth Earphones Noise Cancelling Sport IPX7 Waterproof HD Stereo Headset w/Mic, Secure-Fit Sweatproof Earbuds for Gym Running Workout Exercise

For $30, you really can't get much better than this. It's been around a week now and these earphones are working excellently. At around 70% volume, I clocked the battery life at just over 8 hours constant music playback. I switched to the smaller ear-insert parts because they were 'more comfortable' for my ears, but the default medium size was fine as well. The signal range line-of-sight is excellent, easily pushing 40 feet, though my house's exterior walls (and roof) are metal and I think each wall reduces the range by about 10 feet when the signal passes through them. This is typical of any bluetooth device, so I'm not holding that against these earphones. I'm not a sound quality expert like a lot of people who review headphones, but I believe the sound quality is 'adequate'. I use iTunes to listen to music on my Surface 3 (Windows 10) and I heightened the treble a bit to offset what I felt was a strong bass line. For my purposes, they're great, and I'll leave the fine-tuned critique to other people. Also, the passive noise canceling effect (since they're ear-insert headphones) is nice. It reduces background noises, but doesn't cut them out entirely. I can still tell if a person's talking to me, though I may not hear exactly what they're saying. Pushing a lawnmower, I can actually 'comfortably' raise the volume to drown out what remains of the motor noise-- though I'm sure this still puts the volume into the 'unsafe' range. Also, for safety's sake, I have the audio going to the device dialed down to less than 10% in Windows so that I cannot turn the headphones up high enough that it would actually hurt my ears. As far as comfort goes, I wear wire-frame glasses and these earphones do not interfere with my glasses at all. The ear hooks are very soft and flexible with 'just enough' strength in them that I suppose if the earphones did pop out of one of my ears (not that I've ever felt like they might do that, mind), I'm pretty sure the ear hooks would catch and prevent the earphones from falling off entirely. But since they're not hard plastic, if something did try to swipe the headphones away aggressively enough, they most likely would come off without causing damage to my ear. I call that sort of thing a bonus.A few critiques:- Right after I got these earphones, I went outside to test my range. It was a windy day (30MPH gusts) and the wind noise definitely drowned out my music. ...But I don't use the microphone and never plan to. After going through Windows settings and attempting to disable the microphone, I can't blow on the earphones and reproduce the noise problem. I'll consider it fixed for my purposes, but if you plan to use the microphone on these earphones, you may encounter some issues.- A blue light on the 'front' of the main earphone chassis flashes about every 4 seconds when they're synced. I don't like this because it 'advertises' to people that I'm listening to my earphones... and not necessarily listening to them... The light isn't bright, and I'm sure this won't bother everyone. Personally, I dislike it. So I put a tiny piece of electrical tape over the light. Problem solved. When I plug the earphones in to charge, I can still see a red glow through the seam in the chassis...- Given that I can see light through the seam in the chassis, I don't know if I trust the claim that these earphones would be submersible, but I also never intend to do that with them anyway. I'll trust them for sweat and rain, and that's all I'm concerned about.- One last critique is that you can't use the earphones while they're charging. I do a lot of work listening to music while at my tablet, and it would be nice to listen to the earphones with them plugged into the USB port to charge (using a longer cord, of course). Oh well. I can always switch back to my trusty old cheapo wired earphones... but they don't have a noise cancellation feature like these earphones do!

So far one week in: I was skeptical at first so I did an 8.5 mike run as the first run in 23 degree weather windy conditions. I did sweat too. No issues to report. I did however have one start to slip out as I was adjusting volume with it but that is def to be expected. My fingers were numb and I did not even take the time to choose the right size ear cups prior to running. It comes with 3 sizes also which is great. Charging was easy. Directions easier, and it paired with my new Apple Watch series 3 in a matter of seconds. I never lost signal and I was Bluetooth through the watch the whole time. I did not even bring my phone. Sound quality for the price is amazing. Definitely not bose quality, but it was still great and it cost not even a fifth of the price and is covered for a year.

I am a professional dad so I realized early on that I require a very versatile pair or earbuds. I couldn't go with wired ones cause my kid will grab it and rip it out of my ears. I know I needed wireless but one that's reliable.I stumbled upon these sardonyx wireless headphones. Although I'm not a gym rat, I get my share of explosive cardio workout chasing my dog and running from my office to my kids room.Enough garbage. Let's review these bad boys.The box arrived in great condition and felt like those "premium" boxes you get from a store that rhymes with grapple. I was impressed with the quality. The headphones came prepacked in a leather like pouch. Everything has been assembled and are ready to use out of the box.An extra bag of ear bud sizes are provided if you have Neanderthal earbuds or tiny sized ones you will be covered. A micro USB cable is provided for charging your headphones.The set up was a no brainer. Took less then 10 seconds and I'm ready to rock n roll.The design is slick and works quite well. After wearing them I felt completely immersed and the comfort level is optimal. I didn't feel like I was wearing earbuds. No lousy pressure against ear. I forgot I was a dad briefly while wearing this cause it drowned out my kids screams.I've been wearing them everywhere and testing them out. The functions allow change of music with ease and also allowed phone calls to be received. I felt pretty slick answering a call from my wife in the grocery store. No one knew what was going on as I wasn't using my phone. Voice is crisp and my wife had no issues hearing me.The final test was working out. I took these bad boys to the gym. Went hard on the stair masters. It was gruesome. Sweat gushing down my face as I gasped for air. When I was done with my workout I was swimming in electrolytes. The headphones were soaked with sweat! No problem! Works like a charm still! If your a "sweater" these ear buds are a must!I'll definitely recommend people these earbuds. They're budget friendly and will definitely hold up to serious workouts and everyday use!

Obviously this company has to do something with their quality control, which is a big issue buying brand names you've never heard of. But for the price, if your pair of Sardonyx works, hey... beats the crap out of buying stupid ear sticks from Apple, so you can be 'part of the apple collective' for ten times the price the product is worth, and be really horrible at math, a hallmark of Apple customers. Sounds great. Recharges fast. lasts long. Great for working out. I'd recommend the company firm up their 'ear hangers', because if you hold these things snug in your ear, the sound is insane! Really nice warm bass and crisp clear mid and high tones. But you sort of have to 'press' them to your ear to get the maximum experience. Otherwise, pretty darn good for the money. And if you receive a defective pair, buy another. It's $35. If you can't afford that, then I think you have other problems to consider.
