Review: Just works! - The **SpinFit W1** ear tips are easily one of the best upgrades you can make for your IEMs. They’re super comfortable and the flexible design helps them fit naturally in your ears, which makes a big difference for long listening sessions. The seal is excellent, giving you better bass and overall clarity without messing with the sound too much. They also stay in place really well. Simple upgrade, big improvement.
Review: I'll never go back to using stock silicone tips that come with IEM's and wireless ear buds. - bought these to put on my 7hz salnotes zero and zero 2 IEM's (so far I've only tested the regular Zero). I was having issues with chaffing on a regular pair of JLab M silicone tips that made me switch to their small cloud foam tips, this changed the sound profile a bit by reducing treble just slightly, but those being foam it also made a better deal which helped the bass a bit on those which sit a little back in the sub-bass area (regular zero lack that thump due to a more analytical tuning). So, I wanted to give silicone tips a try again and came across these, the medical grade silicone is soft but sticky and makes for a great seal in the ear, I haven't felt any itching or chaffing so far after a few hours, so I can so far say that the regular silicone tips I used before are no longer going to be put on anything ..in fact I'm gonna replace the tips on my wireless earbuds with these too. The size runs a size bigger, normally with skullcandy or JLab I was using the Medium tip, but with these the MS (medium small) were just about the same fit as those. I might actually get the small because my IEMs don't sit flush against my ears and those would most likely fit a little deeper like the cloud foam tips did for me. As for sound ..my 7hz salnotes zero IEM is a neutral balanced tuning, with the foam tips I can tell the highs were slightly lower and some details in certain sibilant areas didn't sound as sparkly as they should given the tuning, the foam seal helped the bass a bit though. Now for the W1. These not only brought out more clarity in the balanced tone, but it upped the low end a bit where it was brought a little bit forward and wasn't lost or masked while retaining it's set tuning, In fact the bass seems present and tight but not boomy (don't expect a punch from the low end here) which is what you want in a neutral balanced set the mids were nice, clear and kept the balance of the intended tuning, the highs also retained sparkle that was originally rolled off with the foam tips. So in the highs I could hear the faint details from before a little more, but it's not overly sharp. Putting them on is a little tricky at first, they're a tight fit but secure well onto the stem, though I probably would make these permanent on the IEM's I put them on, each one would respectively stay on the ones i put them on, as I heard about these loosening if put on stems with wider diameters and then being too loose on smaller diameter driver stems. The soundstage is a bit more open, I can tell more separation between instruments too. Overall, these tips are great, I may purchase more in MS and S for my Zero 2 and my wireless earbuds.

### ⭐⭐⭐⭐ Very nice!
*by L***S on December 18, 2025*

They stay seated in the ear very well with a nice sound-seal and are aesthetic, but the “stickiness” makes them slightly more difficult to get in when constantly standing up and sitting down at a desk when compared to others like divinus velvet. Overall high quality.
