WCFreeze Momentum 4 - Cooling Gel Earpads for Sennheiser Momentum 4 Wireless Over Ear Headphones by Wicked Cushions - Boost Comfort, Thickness, & Sound Isolation for Epic Listening | Black

I purchased these because the company commented on Reddit about the size, that these were larger than the standard ear cups for the Momentum 4 and so would fit larger ears. I was struggling with my new headphones because they sat ON my ears instead of around them. So I took a chance. I'm glad I did! Installation was easy with these ear pads; Sennheiser finally modified their headphones to have click-on/click-off pads for easy replacement. These look great too - the pattern is very 90s without being overly gaudy. The cushions are super comfortable and very high quality. Since it uses a fabric instead of pleather/vinyl where it comes in contact with your ears, it feels cooler and is easier to clean, and won't start falling apart after a couple of months. I'm happy with the value and quality of the product.

Wicked Cushions Freeze earpads, across the board, add weight to your headsets. You need to know that going into it. Whether that tradeoff is worth it to you depends on your use case (the ol' YMMV). I feel they are a nice change from stock and worth it.With the Momentum 4, the stock earpads are soft and squishy and comfy, provide a great seal and isolation (even with glasses), but are not the most breathable and become pretty hot and sweaty after a bit, especially in warmer weather. Enter the WC Freeze gel pads! I've worn the M4's with the WC pads for a few extended periods and many short periods over the course of several weeks, and they are definitely cooler and more breathable. I find them just as comfortable as the original pads, but it's a different comfort - they're firmer, but still squishy enough to get a good seal, and give your ear a bit more room in the cup. The WC Pads do affect the ANC on the M4, but only slightly - I'd estimate it's about 10% less effective with the WC pads vs. stock, so not a big difference for me, but I can see some having an issue with it in a louder environment. If it's your average office or monotonous hum sound (engine, subway, plane, etc), I'm not sure it will be noticeable.With regards to the M4's sound signature, there is a subtle overall change in the sound. First, please understand that perception of sound is a very personal thing, and for me the WC Freeze smoothed the low end bass out a little, and brought the mid bass forward a little, and barely smoothed out the top end. I also feel it slightly widened the sound stage, but that's a difficult thing to measure with closed-back, noise canceling headphones. Ultimately, it's more of a subtle change from stock that is probably more noticeable to audiophiles, but the change is less noticeable for most people that aren't reading a squig line and fussing over the Hz.

These made the momentums much more comfy to wear for longer periods. It didn't accumulate sweat when wearing these. I would have given 5 stars, but they didn't fully contour the face, so there was sound leakage. Maybe a thicker pad w memory foam would help? The holes were large for my ears, but they likely wouldn't be a problem for most people.Also...I loved the retro pattern!

I rarely write reviews, but I absolutely love how this product has transformed my year old Sennheiser Momentum 4 wireless headphones. I had owned the headphones for about a year, and I preferred them to the Apple AirPods Max for their lighter weight and improved audio quality (when using a BTD 600 adapter). However, I had worn out the earpads on the stock model and the inner ear fabric had begun to popup and tear. I'm pleased to say these earpads have made my Momentum 4's feel like new, even better than new! The cooling on these earpads makes a HUGE difference for longer sessions. I'd even go as far as saying these earpads are better than the default earpads included with the Momentum 4. Please take note of this earpad design Sennheiser!

I've been using the Sennheiser Momentum 4 as my go-to wireless ANC headphone for about a year now, and I always kind of just barely tolerated the drivers pushing up a bit against my ears as the alternative ANC headphones on the market either don't have good enough sound quality for me (really dislike how the Sony XM and Bose ANC headphones sound), or are far too expensive (I would love to daily drive a Focal Bathys but it is...$800). These pads are pretty spacious, so they push the drivers back enough for this to no longer be an issue! They don't seem to get as warm as the stock pads too, which is nice.Keep in mind that I do have medium-sized ears, so these pads fit me pretty well. YMMV though if you have larger ears.Generally speaking the sound seems mostly the same to my ears, with a couple of differences I've noticed:1- Soundstage actually seems to be a bit wider, I think partially due to the drivers being further away from my ears, which is actually quite nice.2- I have noticed more treble presence. I am pretty treble sensitive so this did lead to some sibilance for me on some female tracks at higher volumes, but since I can EQ down the 8kHz region in the Sennheiser app this is not a dealbreaker for my use case. This also may also be desirable for lower volume listening as it does add a bit of extra sparkle and detail.All and all I am pretty happy with my purchase! Originally got these to sort of turn my M4s into something like ANC earmuffs to put over my IEMS (Kiwi Ears Cadenza) for airplane flights or any other situation needing heavy noise reduction (3M earmuffs just take up too much space for my use case). These pads GREATLY help with that use case as they give additional room as to not push against both the IEMs and my ears, and for general casual listening I'm quite happy to have the additional comfort over the stock M4 pads.
