Comply 167 Core Series | Memory Foam Replacement IEM Ear Tips for Sennheiser Wired Devices & More | Superior Noise Isolation, Ultimate Comfort, Secure Fit | Black, Medium (3 Pairs)

I purchased these for my Sennheiser CX 7.00 BT earbuds, and they stay on perfectly on the earbuds very snugly. The foam conforms to my ear, much more comfortably than silicone tips, and enhance the sound quality in comparison to the stock tips that came with the earbuds. I put the first 2 on my earbuds, and have since been replacing them individually when they wear out, which takes a number of weeks for me with a lot of use. I will certainly be buying this product again as they are well worth the money.

These completely transformed my Sennheiser Momentum iems from great headphones to excellent headphones! The sound is enhanced in every way, especially the bass, the noise isolation is insane (I can hear nothing happening outside the headphones) and the comfort is way better than traditional rubber tips. I thought that eartips can't make that big of a difference, but they really do! Now it's a must buy for my every pair of headphones.

I'm a bit of an audiophile per se - I work in music/tv for a living and will only listen to Spotify on premium audio setting if that helps my credentials at all as a snob. But I also like cheap because I have little kids that destroy everything...so what does one do? These Comply foam ear buds are pretty awesome. Just make sure you follow instructions and kind of squish them in with your fingers before you insert into ear, than they expand out in your ear. It's not as crazy as it sounds lol. I got these to replace rather lackluster earbuds that came with latest Sennheiser earbuds I ordered. My only complaint is that the more you take them out and reinsert into your ear the quicker the foam breaks down. Once they lose that firmness and you can't squish them in first, the seal (and therefore sound quality/comfort) is noticeably weaker. They'll eventually rip as well. But $15 for pack of 3, even just a few months per set is good value to me. Recommended for folks that appreciate comfort, sound quality and a good seal on the cheap. It will probably not make bad earbuds much better, but it will probably be better than whatever ear tips you're currently using. Hope this helps.

I just threw away my first pair and they lasted me 9 months. I probably could have gotten a little more use out of them but they were getting a little ragged on the edge and I didn't want to get any material in my ear. I did not use these every day but did use them quite frequently. Maybe 4-5 times a week. My grade is 3 stars because I think the price is ridiculous for these. $5 a pair for some foam is highway robbery. Additionally I felt the material should have lasted at least a year. I tried purchasing a brand (Earphones Plus C-6MF-BKM) since they were only $1.50 per pair hoping they would work but they didn't fit. The center hole was too big. I tried shoving them down to the base to get them to stick and they sort of did but when I put them in my ears the foam stuck in my ears and I had to dig them out with a tiny screwdriver. That was unnerving. Definitely not worth it. The sound was a little different but I liked it just fine so if you can find a brand of foam with a smaller hole in the center I would say go for it. The other differences were that this brand had a less dense foam which made for a more comfortable fit. They are also a little longer than the cheaper brand. I guess I will keep buying these since the tips that came with the earbuds are horrible and these foam replacements make them comfortable and secure to wear.

These are hidden little gems. Who ever thinks to upgrade the eartips unless you lose one? Well, these these are so much more comfortable than the earbud tips provided by the manufacturer and really enhance the listening experience. I have higher end Sony, Klipsch, and ScullCandy earbuds and these make all of those sooo much more comfortable. It's like having little pillows in your ears. The first time I put them in, a little unicorn came and landed on me. Yeah, they're that good.

These foam replacements sound okay but nothing significantly better than the original Sennheiser ones. I find the originals more comfortable. The build quality on these pieces is complete trash. Seriously, after 2 weeks of occasional indoor use you can clearly see in the picture they are essentially crumbling. Don't waste your money on these. They're not an upgrade they are over priced and will start disintegrating soon after normal usage. Stick with the original replacements they're much better.

These are certainly an improvement over rubber earphone tips. I have never found earbuds that would stay in my ears, but these are the only ones that have worked so far. The sound quality is an improvement over the original tips. If my earbuds were a 7/10 before, I would say they are 8.5/10 now. And the sound deadening is incredible. It's like wearing earplugs with music. I regularly wear them jogging with no issues. They always stay in even in +90* weather. I've been using them about every other day for 3-4 months now, and they still hold their shape well. They are starting to get too weak to hold compression when you squeeze them, but as long as you can fit them in your ears they still work great. I have small ear canals, and the standard size fits quite snug. They get a little uncomfortable after a 12 hour flight, but it's not bad. I'd rather they be tight than loose.

I enjoy these tips for my Sennheiser HD1 I purchased in December. I am still on my first pair of 3 sets and I did notice a rip on one side, but I wear these 8+ hours a day at work and take them out a few times through out the day for the past few months so I got my money worth. The only bad thing about it is I bought the large when I should of went small or medium so sometimes they hurt my ears during use, but very rare.
