SennheiserCX 300S In Ear Headphone with One-Button Smart Remote - Red

After a bad outing with the Sennheiser CX 100 (they lasted 10 days before the left earbud died), I decided to try the CX 300S due to its perceived improved build quality.I've had them since April 20th, and so far, so good. The cable is thicker and the 1/8th inch plug is reinforced much more sturdily than the CX 100.These earbuds are *extremely* comfortable. You can sleep in them and you don't even notice them in your ears. Sound isolation is very good, much better than CX 100. When working out at the gym, external noise is cancelled.The bass is also much improved over the CX 100. However, I find that the mids are a touch cleaner with better soundstage on the CX 100. But overall, the CX 300S provides a more exciting listening experience, especially if you're a basshead.I'm really hoping these last. Best earbuds I've ever owned. Worth the price and the sound quality is just on another level entirely compared to the earbuds you get with phones.UPDATE:Best headphones I've yet owned. A few months in, no issues, even after being run over by a car. It doesn't feel like you're wearing them, noise cancelling is acceptable, sound quality fantastic. Only issue is the inline mic is weak at recording field sounds (it's okay for calls) and the jack comes out easy, which I'm assuming was designed this way to prolong the life of the connection at the jack point.I LOVE these. I would buy another in a second. And Sennheiser has a fan for life.

Well, I have been a Sennheiser customer since years ago, and this are no exception to their sound quality and great product reputation. I currently own the HD 4.40BT.Very well built, compact earbuds structure yet sturdy. Flat cables are practical and, even though there is no volume control, the remote for play/pause, next/previous, forward/rewind is functional, and I usually keep my devices at a specific volume level anyway.For those saying that they have no stereo sound or the bass is poor, please make sure you are using the correct earbud tip size for you. The box comes with several tips to fit your ears and make sure it makes the right sealing, so you can have the best sound quality, that is how earbuds work. And in terms of noise canceling they do good work damping external noise without keeping you unaware of the surroundings.BTW, when you use the right earbud tip, there is no issue with noises made by the cables when knocking or rub against the clothing or something like that.The mic has good gain with very clear voice recording.And another good thing is the storage pouch made of syn-leather to keep them safe when not in use.With that said, I do recommend them, I use them when not needing to be wireless or when I don't want to work with BT configurations in video call apps.I did not expected less from Sennheiser.

So, I'm not fond of writing negative reviews, and I really am fond of some of the things regarding these headphones, but.. Here we are.Some positives:1. It looks very nice, I like the color and style2. The medium size silicon buds are relatively comfortable.. After some initial adjusting, they're really good tips! (I will call them tips from this point on)Negatives, and why I'm writing this review:1. The sound quality is.. Off. Specifically, I think there's something off about the bass.2. While it's comfortable to wear, it was actually kind of painful to put in my ears at first. The tips were a little stiffer for some reason. They do soften up after time though, and then they're great.3. The silicon tips... Fall off sometimes. I've don't know how, but I've rarely had this issue with other headphones. It's happened several times, and I eventually lost one of my medium tips (right ear).4. The replacement silicon tips are.. Okay. The small one is the size I chose after the medium, and they look any form of noise cancellation, which means that it's harder to block out sounds if you're in any public space (say, a coffee shop). One of the small tips also fell off (left ear) after a few days of use.5. I've looked around for replacements for these tips for some time, and Sennheiser only seems to want you to buy different tips from a company called Complyfoam, which... Is expensive. I just wish I could get a replacement for the ones that came with these headphones.Overall, the headphones aren't bad (though not worth the $50 price point, I'd say they're valid at $20). If you get these, just keep an eye on the silicon tips!

These are a fantastic sounding pair of earphones at any price. I trust Sennheiser to be good in all ranges and not have disappointing bass. I have two pairs now. I use them with computers (for me wireless isn't worth the hassle then). The pair I already have I've been using daily for something like 2 years with no issues.

I think the big thing to note here is how easily the earbud rotates with respect to its housing. Because it is inadequately secured, I found myself having to constantly rotate it so that it sat correctly in its original configuration. It would get messed up if the earbuds got yanked out of my ear for whatever reason (usually cat). This quickly resulted in the earbud coming entirely detached from the base held on by nothing except the two wires that send the signal/power to the little speaker in there, which inevitably led to a loss of sound, and so now it's just all the way broken.The sound was pretty good, totally satisfied with that. Just the durability is subpar. I have had a lot of earbuds in my time. These earbuds are less durable than most of the earbuds I've had. Below average durability. Given the price, I can't recommend them. If they would have lasted a year I would have had no complaints. They didn't. Therefore, this is my complaint.

This is an amazing value in a wired headset. Very little rubbing sound from the mic. And clear sound on both sides of the conversation. Typical Sennheiser sound.
