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

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.

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.

I had real issues with comfort when using the tips included with the 75t. These needed to do 3 things in order to even match the rubbish jabra tips:1. Fit securely so that they don't come off in my ear.2. Fit in the case so that they still charge properly.3. Sound good and provided good isolation.They did all of these perfectly.Now they just had to be more comfortable than the Jabra tips, and amazingly they are. I still suffer when using the earbuds longer than an hour or so, but much better.So very glad to have found these, great product.

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.

I got some Campfire Audio Polaris II IEMs recently and really struggled with comfort on the standard tips.I get a lot of ear infections and my right ear especially swells inside and can be uncomfortable. I read about these tips on Reddit and wanted to give them a try.I put them in and amazingly I got a seal and a comfortable fit in one hit. The sound is crisp and clear but now I also have the feeling of not knowing I'm wearing the IEMs at all.I'm sold straight away, I can't speak for durability but I have 2 sets, they look like they will stand the test of time.Try them out!

Bought for Sony w1000xm4, and lasted less than 3 weeks. Fit was good but the cone separated from where it attached to the earbud. First time I've used them and so won't be recommending.

Bought these to replace the generic tips on my IEMs after I lost one. I am not an audiophile or ultra particular about my music, but I do appreciate good sound. I never had a problem with the default tips included on my IEMs but these have distinctly more mids and less bass in comparison. Not necessarily a good or bad thing depending on your listening preference. They seal just as well and are just as comfortable in my ears as the default tips, but are harder to clean due to the ridge in the center hole if your ears are prone to wax buildup.I didn't have a problem with my default tips, and its nice that you get two sets, but I don't think it is worth the extra cost over generic tips.
