Comply TrueGrip | Premium Memory Foam Replacement Earbud Tips for Sennheiser Momentum 3, 4, ACCENTUM | Enhanced Comfort, Secure Fit, Superior Noise Isolation, Cleaning Tool | Black (S/M/L) (3 Pairs)

First impression: I used the medium silicone tips and read that these foam tips run a little small, so I ordered the large size. It was definitely the right move! These foam tips are much more comfortable, and I appreciate that they stay in my ears better. My sound experience has slightly improved because of the added seal these provide. I don't ever feel like I need to take them out to give my ears a rest.

These really do work for the Sennheiser Momentum 4 earbuds. Better than the factory issue.

These are not bad eartips but not great either. I have always been a fan of Comply tips and have used them for years on my Shure ear buds. These fit the earbuds fine but just don’t give a great seal so the sound quality isn’t as good as it should be. I couldn't get a good enough seal to pass the eartip test in the app. Looking at them beside the OEM silicone tips they aren't quite as big as the OEM. I can't go bigger because I use the largest tips available. I really wanted these to work.

Out of the box, I wasn't sold. They need to break in a bit. The stock ones are mid at best. These are a huge improvement, especially if you have bigger ears. Zero regrets.

They have been very finicky for me and teg volumes is a lot lower. When I first put them on they were great but it's been getting quieter everything I put it in. Not much better than the OEM ones sadly. In my opinion a waste of $30

Sizing def not accurate . I got a small. And compared to the stock size S def is different.
