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: Didn’t really work for my earbuds - I could see straight away, they were too shallow to replace the earbud cover I had lost. I found it tricky getting the measurements right.

### ⭐⭐⭐⭐⭐ Ideali per chi ha il canale auricolare stretto.
*by D***O on 6 April 2023*

Ho il canale auricolare stretto e gli auricolari in-ear mi causano mal di testa e irritazioni all’orecchio. Gli spinfit mi hanno salvato: posso tenere gli auricolari quanti voglio senza avere più mal di testa! Consigliato a tutti quelli che come me soffrono gli in-ear.
