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

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!

I bought these for my Etymotic HF5s, as the original tips were unbearable. These are so much more comfortable and I can wear them for a few hours at a time without too much discomfort. The small is the best size for me (someone with fairly small ear canals, I guess) but I can also wear the medium. I can't say too much about the noise isolation as the Etymotics are so good in this regard that I can't tell if the tips would work regardless of type, but I can say that coupled with this type of headphone, they work really well. As soon as I play music, I can't hear any external noise.The worst thing about these, as has been said over and over, is that they break quickly. One of my smalls has already ripped, and the other is on its way out. Because you have to compress them to get them in, especially if you're using slightly larger ones, all that rolling is bound to take a toll and eventually they do lose their memory foam qualities. Mine don't really squash down any more, they simply spring back to normal size, and eventually I will have to replace them. As they're pretty expensive, I'm not too happy about this, but they're so good that I will probably keep buying them.

I ordered these after buying a set of Cambridge Audio Melomania 1 plus earbuds. The foam tips that come with the buds are...Ok, but both pairs of medium tips disintegrated after two weeks of moderate use. I did a lot of searching around to try to find some replacements/upgrades and found these. I'd read some reviews that said they don't fit the buds at all. They DO. They do need some careful fitting but they do fit reassuringly well. These Comply 600s are a lot chunkier than the tips that come with buds but I could tell that the quality was far superior to the originals. The one downside is that the buds now don't 'snap' into the charging case as they do with the originals and that was a lovely little tactile joy, but seeing as that's not my primary use then it doesn't bother me too much. And I read from other reviews that have fitted these to the Melomania 1 plus that they don't charge in the case and the buds stay connected via bluetooth to your device... I can confirm, for me, they do charge and they do disconnect from the device.I think the Melomania 1 plus are fantastic little things with a massive sound and these tips make that sound so much better. When you scrunch them down to fit into your ears they expand and create a really good seal. THEN you get the true power of these buds to ramp up. I can definitely recommend these little things if you have a pair of the Melomania 1 plus. As for durability I can't comment as I only received them today, but they certainly look like they might last longer than a week!
