Comply Isolation Noise Cancelling Memory Foam Earphone Tips for Sennheiser HD1 Momentum MIE2, IE 800 S, CX 3.00, 5.00 and 7.00BT, Premium Replacement Earbud Tips, (Medium, 3 Pair)

I'm rocking a pair of Sennheiser Momentum M2-IEG cabled in-ears. I picked them up around 5 years ago and they still sound and work great. The issue I was having was that the included ear-tips were becoming increasingly loose and I was often finding they fell off. I was originally going to buy a replacement set off Sennheiser directly before I came across these ear-tips by Comply. I'll summarise my thoughts below: - They're incredibly comfortable. I cannot stress this point enough. This observation is coming from someone who struggles to wear in-ear headphones normally, and who often starts to experience ear ache after only a couple of hours. I've managed to have these in for a full working day and have minimal to no discomfort. - The sound isolation is just ridiculous. I guess this is due to the fact they're made of memory foam and you get an incredibly tight, tailored fit inside your ear canal as the foam expands to shape. This is probably the most impressive passive noise isolation experience I've had. - They've transformed the sound of my headphones for the better! Owing to the better sound isolation, I'm finding I can listen to music at lower volumes now. The sound also seems more like an open back headphone as opposed to a closed back one, which surprised me as I feel these ear-tips directs the sound more in the ear. The bass remains unchanged however, not that this is a bad thing! - The fit on the headphone is very secure on the connector. I have no concerns that they'll fall off anytime soon. I was initially hesitant in buying these for two reasons - the high price tag and the reports of poor durability. Whilst I acknowledge that these are expensive they are definitely the best ear-tip I've used by far. I can't comment on the durability of them though as I've only had them for a week. I would recommend them to anyone who is thinking of buying!

These do all they claim - perfect and very secure fit, amazing sound and always comfortable. Unfortunately by the time I got on to the second pair ; they already seemed to have lost some of their elastucity/capacity to expand and fit as well as the first pair. It seems the material is past its prime and is slowly deteriorating. If you are a jogger then you'd probably get through all 3 pairs supplied and reap the benefits but personally I find it expensive for one perfect pair and 2 less so. I would still say try them as they are the best fitting buds by far.

These are epic. Very comfortable, can have them in longer, can smile and shake my head as much as I like they sit firmly due to them decompressing and fitting much much better. They are ultra silent, the noise cancellation has definitely increased 2-3 fold. The bass is crazy, I'm giving 4 1/2 stars instead of 5 because I would love the full spectrum of highs here, it's oh so almost there, for me with the mid-sized earbuds. Middle are spectacular too. Do not hesitate to increase your e perience with any hear buds with these, 100%.

Absolutely awful. I have bought this product twice. The second time to ensure I did not get a faulty pack. These earbuds, whilst boasting decent sound isolation and comfort, are the least durable set of earbuds I have ever had. For the price this is atrocious. In both occurrences I have followed the instructions on how to use them perfectly, however I went through all 3 pairs of earbuds within the space of a month an a half. That's right, it took approximately 40 days for all 3 pairs in the set to disintegrate and lose any of the defining qualities that apparently make this brand so "great". So what happens? Well each pair of earbuds lasts around 10-12 days at best. Using them as per instructions (i.e. squeezing the memory foam before inserting them into the ear) you will see that a split has occurred in one of the earbuds on the 9th day. This is your 3 day countdown and the end of any sound isolation. Within the next 3 days, the earbud will soon disintegrate from every use. Chunks of memory foam will fall off every time you take the earbuds out of your ears and you will face the concern of potentially having foam trapped against your eardrum. I cannot stress enough how terrible this product is. I understand it is difficult to ensure that you are getting the correct size earbuds for your earphones but I strongly advise you move past these ones.

They seem to be good quality, although I can’t comment on how they perform since they do not fit on my Seinnheiser Momentum TW 1 earbuds. This is disappointing given that the product description did not indicate they were incompatible with certain models. The seller should make their product description more specific in this respect.

How these can make such a vast improvement is beyond me, but they do. I was dismayed with the sound I was expecting from my Sennheiser Momentum in ears, it was really bass heavy and very muddy , not clear at all. Replaced with these tips as a last ditch effort before I binned them. Revelation, now I can hear that they are in fact quite good. Sennheiser, PLEASE put some decent tips in from the start.....

Wow. Ok so full disclosure I didn't buy into the marketing with this. I read a review about the Seinheizer Momentum 2 in ear which I just purchased were the reviewer made a comment that these tips work with them. My awkward ear size which is slightly bigger than a small and slightly smaller than a medium makes it very difficult. And with the Momentum the ear tips that I had kept for years didn't fit. That is the only reason why I purchased these. Because they fit on the Momentum 2. And I received th shock of my life when these came though. They did an amazing job at fitting that award ear shape of mine as they expand. They are extremely comfortable, and somehow, though some black magic or something they do not effect sound quality at all, they might even make it better. High-hat snares are not sharp to the point that it hurts anymore (an issue I have with th Momentum earphones) and probably most importantly, no matter what I tried, they would not fall out by themselves. I tried jumping, spinning, tugging at the cord as if caught on something. And they stay planted, still as comfortable as ever. 100% would recommend

Very comfortable, better noise isolation compared to standard silicon buds that come with the product however, be warned, you cannot remove the foam bud without destroying it, the foam WILL tear when you try and remove it. The one comfort in this is that you know your comply is secure on the earbud and won't come off when you pull it out and get stuck in your ear canal unlike the comply foam bud I had on my SoundMagic E80c earbuds. I had to remove it carefully with a paper clip as I was miles from home on my motorcycle.
