SpinFit CP350-S - Silicone Eartips Replacement for True Wireless Earphones - 2 Pairs - 5mm Nozzle Diameter (Small)

Been looking for suitable tips for my FIIO FH5’s. Using Inairs on my Shure SE215 which are perfect for those. Didn’t work at all for me on the Fiio’s. Felt like they were jammed in my ear and effected the sound, lots of low end but dulled the mids / highs. Similar experience with Comply tips on the Fiio’s too. Tried the Spinfit 155 (medium) which gave a lovely balanced sound, to my ear anyway. They were just a little loose on the nozzle and a tad too long which irritated my ear canals after a while. The Spinfit 145 (medium) are perfect. Snug fit on the nozzle, good seal in the ear canal and used for hours with total comfort. They give the earpieces a better, secure fit than the supplied tips fromFIIO. Lovely low end thump but with all the clarity the FH5’s possess. For me the 145’s are a perfect match with the FH5’s. Very subjective I know, but hopefully helpful for anyone looking for suitable tips.

You know, I'm starting to believe that when people say earbud fitment is a problem with certain buds, what they really should be saying is that the tips fitment is the problem.*The Story*I have had the Google Pixel Buds for about 18 months but the left ear would always fall off. I got the One Plus Buds Pro recently after travelling and forgetting the pixel buds. Upon discovering that all the included tips were not perfect for me, I decided to try a different approach this time out, I knew I'd need something smaller than the smallest tip, yet wider at the tip bottom, so I did some measurements and searched amazon for tips that matched them.Voila, I ordered these bad boys having ordered the CP 360 in the past to solve the same problem for my Pixel Buds and they fit perfectly. They have a good seal and thus noise cancellation on the One Plus Buds pro works as intended. The additional surprise was that they also fit my Google Pixel Buds and they make them feel like I just got 2 new earbuds and not one.*Quality*These are very well made as I've come to expect from Spinfit. I love the transparent-like dark grey look and you get the sense that they'd hold well for a very long time.*Sound + Noise Cancellation (+ Fitment)*While people would typically attribute earbud tips to sound, I attribute sound to getting a good seal and for these, they get a good seal in my ears thus the sound quality is great and Noise cancellation was noticeably better than when I'd used other tips for the buds.*Overall*Get this if you've got small ears like mine but try taking measurements to be certain before you get them. Chances are that these will be the best tips for you or they won't be if you got your measurements incorrect.

They are expensive especially when you factor in that you only get two sets of tips. Putting that aside though they are very good, they fit tightly on the earbuds so won't be left in your ear. They are quite soft so make a good seal in the ear but are still comfortable. I only wear my buds for about two hours at a time and not have suffered from ear fatigue in that time.

Spin fit ear tip upgrade for better fit and improved sound and bass

I purchased these for my KZ Z1 TWS earphones as I found the original tips didn't go very deeply in my ears and I was struggling with the fit.The Spinfit eartips are more comfortable and provide a better seal and fit than the originals; however, they change the sound a little by increasing mid bass. You may not mind this; however, I preferred the cleaner sound the originals give. The mid bass bump is only slight and you may not mind it.The SPINfit eartips are about 3 or 4 mm longer than the originals and while the IEM's still fit in the case and charge, they protrude more and this appeared to affect the auto on/off - If I took the IEM's out and popped them in my ears they would not connect with my phone, as they were off, and I had to switch them on each time which was a bit of a faff.Ultimately, I went back to the original ear tips.Oh, and £15.00 a pack - someone's making a killing on these!I can't recommend these for KZ Z1 owners.

They are always excellent products. I bought the wrong size so they slip off ( I also have 8 pairs that were the right size)but in terms of audio performance absolutely can't be faulted. Spinfit always improves the audio on my IEMs from the ones that come with the product. I would totally recommend them if you use IEMs.

Don't know whether I've got a defective pair, but the rubber seal doesn't grip around the nozzle/spout of the earphones tightly enough, meaning that unless I remove the earphones with the greatest of delicacy from my ears, more often than not the tips remain stuck in my ears. This is the same on the BLON BL03 and Campfire Audio Andromeda iems I own. I've never had this issue with any other pair of tips I've owned apart from ones where the silicone has began to loosen and stretch after months worth of continuous use.The seal in the ears is good, the sizing is accurate but these are unusable for me for this reason. The 'spin' element seems entirely like marketing hype. These are entirely bog-standard, neutral sounding tips. If it wasn't for the defect I'd be largely happy with the sound/seal.

Provides a better seal and noise cancellation for the Jabra Active 75t.These tips change the sound quality slightly, but nothing major.I was between the small tips and medium tips from my original Jabra Active 75t, and found the small fit perfectly and they are so much more comfortable.
