Comply Memory Foam Replacement Earbud Tips for Sony True Wireless Earbuds | Ultimate Comfort, Secure Fit, Superior Noise Isolation | Anti Slip, Prevent From Falling Out | Black (S/M/L) (3 Pairs)

These earbud tips work really well as a replacement for the WF-1000XM4 stock tips, but you should expect to replace them somewhat frequently. Because of this, it is a much better choice to buy a 3-pack of a single size than to get the assorted pack.Pros:- They provide almost perfect noise isolation in combination with the ANC.- They are very comfortable and I can keep them in for hours on end.- They don't slip out.- The barrier keeps earwax out of the actual earbuds without affecting the sound quality.Cons:- They wear out over time and will need to be replaced. A pack of 3 pairs can last me about four to six months.- Noise cancellation will worsen the longer you go without replacing them.Edit: my most recent set lasted me quite a bit longer (just under 6 months), I feel like this is satisfactory so I've updated my review accordingly

The Comply Foam Eartips are a revelation in the realm of earphone accessories, especially when paired with the Sony WF-1000XM4. These tips are a game-changer, offering a myriad of benefits that transform the listening experience.Firstly, their superior isolation capability deserves applause. They create a snug, almost custom-like fit, effectively sealing off external noise, allowing you to immerse yourself fully in your music without any disruptions. This enhancement in isolation significantly contributes to an elevated level of clarity and detail in audio playback. It's like stepping into a cocoon of sound where every nuance becomes vivid and pronounced.The performance boost is tangible. The Comply Foam Eartips act as acoustic enhancers, subtly fine-tuning the sound profile, delivering an impeccably balanced audio output across frequencies. The lows are richer, the mids more defined, and the highs crisp and clear, allowing you to truly appreciate the depth and intricacies of your favorite tracks.One of the most remarkable aspects is their unobtrusive nature. Despite their incredible performance, these eartips remain comfortable for extended listening sessions. They mold seamlessly to the ear canal, providing a secure yet gentle fit that doesn't cause any discomfort, even after hours of continuous use. Their ability to stay cool and dry under regular use is a testament to their thoughtful design.Moreover, their ease of maintenance is a huge plus. Cleaning is a breeze, and they even tolerate light alcohol use for sanitization, unlike the OEM tips that suffer structural breakdown when exposed to alcohol. This durability and resilience ensure a prolonged lifespan, making them a reliable and long-term investment for your audio gear.In essence, the Comply Foam Eartips are not just an accessory; they're an indispensable upgrade for the Sony WF-1000XM4, enhancing every aspect of the listening experience while prioritizing comfort, durability, and hygiene. They are, without a doubt, a must-have for any audiophile seeking to optimize their earphones to their fullest potential.

All three sizes fit my ears well and do not cause pain unlike the stock tips. Comfortable to wear the earbuds throughout the whole day. Using these tips for more than a year now.Sound quality issue:As others mentioned, sound is muddier and worse in general, but easy to fix. All you have to do is remove the "TechDefender" filter. You can easily poke it with a needle and peel it off. Be careful not to rip the foam itself. Then the sound will be the same as on stock tips.Build quality issue:After some time the inner core separates from the foam and there is risk of the tip getting stuck in your ear when pulling out the earbuds. I believe this is because pinching and rolling the tip a lot of times makes the connection weaker. Probably have to replace the tips every 3-6 months, depending on usage. But for this quality and price it's not a big issue (I suggest ordering multiple packs when on discount).Overall these tips are the best option to replace the stock ones, and I never had the earbuds fall out. Highly recommend.

I've been using Comply tips for years, starting with a few sets of Shure monitors and more recently with several generations of Sony WF-1000XM. I usually wear earbuds for 2-3 of hours a day; some days a few more and others not at all.The smalls are a perfect fit for me. On the day they're installed, they're comfortable and sound great, with clear highs and tight bass. They also isolate outside noise exceptionally well after expanding over ~30 seconds following insertion. They continue to perform that way for 3-4 weeks, after which it becomes apparent they're wearing out. They expand more quickly after being compressed making them more difficult to insert, the sound lacks power in low frequencies, and the isolation begins to fail. I can usually deal with the continued decline in performance for another 2 weeks, after which they have to be replaced.One particular set I must have used too long, because at about the 8 week mark, I noticed the tip had ripped away from it's rubber gasket on its way out of my ear. It was still attached, but with any more resistance it'd have broken off in my ear and been difficult to get out.Update Nov. 2024: Came back to buy another set and they're now asking $8 more. At 6 weeks average use, that's $75 a year on earbud tips, so my quest for something better has begun.
