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, Medium (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

These ear tips are very comfortable, but they aren’t meant to last. Keep in mind you will need to replace them.The stock ear tips are extremely painful to me, and cause my canals to chafe and hurt very badly. These tips are extremely comfortable in comparison. When you order these tips you get 3 pairs, and those 3 pairs seems to last me about 2 months. They get softer the more you wear them and begin to lose their firmness. Eventually they just start falling off the stem.These tips are 100% worth it, and are among the best ear tips I’ve ever had for any IEMs, just keep in mind that they need to be replaced frequently.

UPDATE: On multiple, multiple occasions, I’ve had these eartips pop right off my WF-1000XM4 when I go to remove them from my ears, requiring tweezers to remove from my ear. That’s an issue, and someone could end up damaging their eardrum trying to remove one of these. I’ve also just had one rip from normal use. I hope they fix these issues, because these are otherwise great.ORIGINAL REVIEW:TITLE: They really are as good as the reviews say. Boosted ANC and comfort, minimal difference in sound.For context, I’m a big fan of Sony’s 1000X line, but I had to return my WF-1000XM3 because they caused my ears so much pain. I recently made the jump to the WF-1000XM4 in the hope that they’d be more comfortable. They are, but they still left my ears sore quite often, and wearing them for several hours on end could cause rather sharp pain. I thought about several different options for third party ear tips, but what really sealed the deal on these for my ears was the filter these add to prevent earwax from entering the nozzle and degrading the earbuds.Now that I’ve used them for a few days, I can tell you that these actually improve the noise cancelling — in fact, there are some sounds, like my mini fridge, that I could still hear on the stock ear tips, but are completely silent with these.I also noticed on the stock ear tips that in my left ear I sometimes heard a rustling noise, like an ear hair was rubbing against the headphones. It was getting on my nerves, and I thought there was no way to fix it. With these, the sound is gone.Oh, and the earbuds don’t shift around in my ears on their own nearly as often anymore. That wasn’t a huge problem before, but now they’re secure enough that I think these ear tips are a good purchase for runners.But most of all, what’s great about these is the comfort. I could only wear the WF-1000XM3 for an hour before the pain was too much to handle. On the WF-1000XM4’s, it was maybe 2-3 hours. But with these ear tips on the XM4’s, I can wear them for basically the whole day with no pain, and only mild discomfort if I don’t take a break for a few minutes after 4+ hours of continuous wear.I was afraid I’d need to pinch these before inserting them, but I don’t, and it’s fine. I just kind of tilt the earbuds around as I reset them against my ear, and then push in as I go, and I get a really consistent fit that stays put in my smallish ears.So yeah, I love these, but they’re not flawless. They’ve got one minor flaw in my eyes so far. They make the headphones sound very slightly different. It’s quite subtle. I can’t quite place my finger on it, but there’s something a little different. I think the volume might be ever so slightly less, and some details sound just a bit less crisp than before. However, some details sound a bit more crisp. I’m not sure what it is, but I’ve already gotten used to it, and I’m not looking back.

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.
