Review: Perfect fit for both my Google Pixel Buds and One Plus Buds Pro! - 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 desertcart 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.
Review: Expensive to but worth it - 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.

### ⭐⭐⭐⭐⭐ Perfect for FIIO FH5
*by L***B on 4 March 2021*

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 from FIIO. 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.
