SpinFit Omni for True Wireless Earbuds & IEMs - XL - Patented Silicone Eartips for Replacement (1 Pair) (3.7 mm Nozzle Dia.)

Got the SS size; I had the S size of these previously and was equally impressedby these. The ear tips are a tight fit on my Artti T10 IEMs, but at least once they're on they're nice and secure. A more comfortable fit for my small ears than the S without compromising on sound isolation or quality, and, as I previously remarked, there is a notable improvement in sound quality over the tips that come with my IEMs. The silicone is comfortable, grippy, and feels durable, I'm not afraid to be rough with the tips with my nails to get them on. Whilst pricey, I can easily recommend them nonetheless.

Can confirm that these fit on Beats Fit Pro.Haven’t been able to find any other confirmation of this so here it is.

To the average listener you might not recognise the value in these but it’s money well spent.I’d previously used an old set of Spin Fit tips on some KZ IEMs and recognised the difference in sound quality they made.I wasn’t sure on the fit this time around, as my ears seem to have gotten bigger, and the ear tips that came with the Ear Fun’s I need to use the largest set for comfort and seal (especially in my right ear; my left seems to accept any size).Due to reviews suggesting they’re snug I went with the Large, and seeing as their silicone is slightly thicker but still flexible the fit and seal is perfect; and there’s enough grip that they don’t shift.Sound quality is improved also due to the ear tips not covering any of the driver hole; where as the provided tips did ever so slightly. This appears to improve the quality of the low end and provide a more rounded and improved bass and sub bass presence.Highly recommended

I bought a pair of earphones (Oneplus Buds 3), and they are really nice sound quality wise, but my ears just don't cope well with earbuds of any kind. I was willing to try these because of the reviews of them being comfortable and fitting well in the ears, but turns out my ear canals are just still too small for the smallest tips that come with them. I decided to give the smallest spinfit size a try, hoping they'd solve my issues and keep the earphones from falling of my ears (especially my right) every second.I have to say, I was worried because the nozzle on the 1+ B3 are pretty big and I wasn't sure the tips would fit. They did...just barely lol, but they did. I have to say, that the second I put them in....massive difference. I finally have eartips that fit my ears and I get the full audio quality that I paid for. They're super comfortable...used them for about 2 hours straight right after and didn't have any discomfort at all. Had the issue before where my earphones automatically pause playback when the earphones are taken out your ears and because the tips that came with it were too big, my music and videos would just stop randomly. That issue is fixed now. All in all, one of my proudest purchases. 8/5 stars.

Good fit and comfy but the moment you sweat even the smallest amount during exercise the tips lose any grip and just slip out your ear.

I recently bought a set of Nothing Ear (a) earbuds and, as great as they are, I couldn't get a good seal in my right ear. The stock tips are slightly oval, which is probably the reason why, because I've never had an issue with other earbuds (Sony, Sennheiser, etc).Anyway, I decided to try these as a replacement and at almost ten quid for a pair I knew it was a bit of a gamble. It took some effort to get them on the Ear (a)'s because these tips are round and the Ear (a)'s have an oval stems, but they went on and instantly made a big difference - i.e. notably more bass, meaning a decent seal.They are expensive for what they are but, at the end of the day, if it improves com fort and audio quality then they're a worthwhile investment.

The quality of the eartips is great, the flexible nature of them does increase comfort, however I don't find they fit my ears as well as I was hoping. They are a good quality, durable silicone that's on the stickier side so they stay in your ears well! They are definitely on the pricey side though at £10 for a pair

SpinFit are good well fitting and comfortable ear-tips. Improvements and changes to sound quality are very much down to personal preference as everyone’s ear shapes and hearing is different. Play around until you find the ones that are right for you and the IEMs that you use. Would recommend - a good one to keep in your collection.
