SpinFit W1 for IEM - M - Patented Medical-Grade Silicone Ear Tips, Double W-Shaped Tube Core, More Stability

After trying several different kinds of tips, these are by far the best. 5-stars for an awesome comfortable fit and the sound quality enhancement they produce is exactly what I needed.What sold me... I have Soundcore X20 sport earbuds that I use as my daily drivers. I'm outside and sweating a lot, they have proven to be perfect for my uses. But they have a baked in bass-heavy sound signature, and although adjusting EQ settings does help reduce the muddy/boomy sound they produce with their stock silicone tips, it still does not completely get rid of it. With these tips installed, however, bass frequencies are cleaned up immensely and the boominess is absolutely gone. They actually do such a great job at bass retention that I can now bring the bass/mid-bass EQ settings up from zero. Which is fantastic, because they are now within the tunable EQ range provided by the Soundcore app.Bass is now very clean and tight (think sealed acoustic suspension woofer), soundstage has increased noticeably, instrument separation has improved, and the rest of the audio spectrum is clear and crisp. They are so comfortable, making them very pleasant to listen to for long sessions. The only downside is that the X20's will not fit into their charging case without removing the W1 tips first. But for me, this is well worth it the small inconvenience.I highly recommend these, especially if you have bass-heavy IEM's like the Soundcore X20 Sport, or any other IEM for that matter.TIP: I recommend also trying the next size smaller tips than you would normally purchase. I tried all four sizes, and they ALL fit my ears good enough to provide a nice, comfortable seal and great sound. This, to me, was VERY impressive. I normally use the M size, and they fit fantastic, however I found the MS size to also fit my ears with maybe just a little more comfort. S was just a slightly loose fit, L was just a slightly tight fit. I kept both M and MS tips in my collection; I use the slightly more secure-fitting M tips outdoors while active/working/sweating and use the MS size for indoor/casual listening, as they are slightly more comfortable with less pressure in my ear canals.These are fantastic tips, such a great product. Easy 5-stars.

Bought these tips after losing the stock ones. Truthear Hexa has a stupidly large nozzle, I've shaved it down to 6mm a while ago and the tips barely fit. I had problems with the stock tips sealing and these tips fixed the issue. The sound is quite impressive with the tips. It feels like it has better sound separation, it tightens the bass up. More punchy than before. First use and I thought I had open back headphones on because of the increased sound stage. Obviously it doesn't compete to an actual open back soundstage, it doesn't have that fullness to the sound.

I really enjoy these but honest to god there is too much packaging for a single set of these and I also wish they sold them in sets of 3 rather than just 1

Replaced the tips on a Hidizs MP143, and they finally have a good ear seal. No problems with the sound either.

I use this with my Sigmond Supermix 4s, amazing. Worth every penny.I use them to game, and use them for hours on end, and they are comfortable for those long sessions.

These saved my ability to use IEMs. All other tips make my ears burn like fire after an hour or so. Must be material sensitivities. Anyway, these I have used for 8 hours a day with no issues. They seal well and are comfortable.

The w1’s are definitely my favorite. They are a little longer so they sit slightly deeper in the ear which i like. I can tell an up in bass and clarity with my soundcore p40i’s. They are grippy and have yet to fall out my ears when i work out. I will buy more for other ear buds i have. Great for the price.

theyre okay
