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)

These tips are excellent replacements for the Sennheiser Momentum M2 In Ear phones (although not specifically marked as such here, they are specifically made for these earphones). I personally prefer them to the original tips, as they make a better seal when inserted and fully expanded. The bass response is quite a bit better as a result. Also, they are more comfortable for long periods.It's a personal preference thing, of course, but definitely worth giving a try, especially if you've lost your original tips!

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.

The size is not fully fit my Sennheiser Momentum True Wireless 2. But, it still can fit by a little force.

Honest opinion. I have had several pairs of inairs which are good. These were the only ones available for my sennheiser momentum in ears. I saw these became available for my sennheiser so bought them even though they are more expensive. Way better although inairs good. These are a softer foam and a smaller tube. The go into ear canal further so I would prefer these

In terms of compatability with the sennheiser momentum 2.0 headphone they fit great and the comfort and sound improvement over standard tips is immense. if it wasn't for the durability issue mentioned below these would easily be 5*.Unfortunately they are not very durable at all. They tear very easily and quickly just from putting them in and out of your ears. Due to the tears I'm soon going to have to start on the 3rd set and i purchased these 3 months ago. I only use my headphones whilst sitting at my computer so they don't get rough handled at all. I estimate i'll get another 2-3 months out of them before they become unusable. £16 for eartips that last 6 months i don't think that's very acceptable.I would still recommend just on the caveat that you purchase knowing they will not last and you will have to rebuy.

For the price i was expecting a lot more from these. Looking at the 3 areas that we are meant to rate...Sound quality - these are not headphones and therefore have little do do with sound quality. They have a hole, and let sound through. End of.Durability - poor. Noticeable wear after just a week of wearing. Also impossible to remove without significantly damaging the product.Noise cancellation - this is what most disappoints. After wearing for a decent amount of time (enough needed for the memory foam to expand and fill the ear canal) the amount of noise cut out was minimal. Given the extortionate price, staggeringly minimal.Added to that, personally i find them quite uncomfortable. I use the medium size (as i do for sennheiser tips) and after 20 minutes or so there's a dull ache in my ear. The smaller tips are just to small so it's not a case of using one that are too large.So these aren't useless, or shoddy. They're just not worth the money. At all.

Good quality and isolation

I tried these because I was enthusiastic about the Sennheiser Momentum earphones I'd purchased. The headphones are great and already come with a selection of tips of various sizes.By comparison, the Comply Isolation Noise Cancelling Memory Foam Earphone Tips are ONLY ONE SIZE and awkward to use (they need to rolled between one's fingers) and I found that as they expanded they exerted too much pressure on my ear canal.In short, they turn excellent and comfortable earphones into very uncomfortable earphones.And there is no 'noise cancelling' function in them at all. Complete waste of money.
