SpinFit CP145-M - Silicone Eartips Replacement for Universal IEM Earphones - 2 Pairs - 4.5mm Nozzle Diameter (Medium): desertcart.co.uk: Toys & Games

Review: Perfect for FIIO FH5 - 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.
Review: Alright, if expensive - 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.

### ⭐⭐⭐⭐⭐ Amazing
*by J***N on 23 May 2020*

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!
