SpinFitCP240-S - Double-Flange Silicone Eartips Replacement for Universal IEM Earphones with 5 Inserts - 1 Pair - 4mm/2mm Nozzle Diameter (Small)

Purchased for comparison tests against other silicon, foam and TPE (AZLA) eartips.These are now available £5 cheaper elsewhere on Amazon!Using on Moondrop Aria iems, replacing compli foam tips (which had just started to breakup), they fit output nozzle sizes of 4.5 to around 5mm, the Arias being at the upper limit for fitting being 5mm or slightly over.The silicon is comfortably soft, easy insertion and retention, design much the same as others in this price tier.External noise reduction, tested with unconnected iems, TV set at volume level "10" at ~2m away, could still hear TV, sound muted but distinguishable.Sound slight bass emphasis, mids clear enough, treble slightly elevated.These are not a lot different to other silicon tips, at the price paid they are relatively expensive for 2 pairs of ear tips that don't really stand out from the crowd.

Fits on Google Pixel Buds and is smaller than their smallest option. Perfect option for tiny ears.

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.

I have tried these on westone w60 v2, compared to the star tips the treble is extended, more open and spacious sound at the cost of less weight and depth in the bass and i also think the mids are slightly more recessed. I mostly listen to pop and rock and tend to favour bass quality and quality so these are not for me but are an excellent choice if you want to improve the treble.

These are OK but not really better than the regular SpinFit tips. A little less comfortable in fact, as the rear edge of them can be a little irritating to your ear. The most useful thing about them has turned out to be the tiny tube fitting adapters which let me use a variety of tips I already owned on IEMs with different size tubes.

I found that my in-ear buds weren't fitting as securely as I wanted when I used the eartips they came with. I read that SpinFit were better, and they are - somewhat. The Extra Small is smaller than you can buy from most brands, and the silicone isn't as "slippery" as the material of most buds.However, they aren't perfect and do tend to eventually slip out - but more slowly than most buds do.£15 is pricey though! For that, you do get two pairs, but in different sizes, which means one of them is no use. OK, you might want to try two different sizes, but if you know your size then forcing you to buy two makes you feel like you're being taken for a ride.Please either sell these one pair at a time, or in packs of two same-sized pairs!

The noise cancelling is perfect, which is great for busy offices. A good price and if I need anymore, I’ll come back for these. I’ve had more expensive foam ones that end up tearing and these are just as good, without any chance of them tearing. Buy them

i have sennheiser ie800 iem's very expensive but legendary iem's. i struggled with sennheiser's supplied tips, i found non of the supplied tips every fitted properly. these were the only iem's that i have had this issue with. B & W c5, shure se425 no issues at all. but sennheiser i just could not get to seal properly and the complys made the bass all mushy and overblown and sucked out the upper mids and high end. this had the undesirable effect of severely reducing the soundstage for which these earphones are renowned for. after a lot of research due to the proprietary fitting a clip and very short nozzle, spin fit cp100 seemed to be vocalised on many forums.they fit nice and tight on the stub, they are very comfy after 5 mins its as if they arent there. not sure about long periods as ive only just put them on.the audio experiance is awesome, even better than stock, the tips go in slightly deeper, all the attributes that the ie800 is famed for are there in spades, deep deep bass but not boomy or overblown, sparkly highs some might say too much, but never does the treble go sibilant, voices are right there and the sound stage is wide and 3d.be aware if your source is poor i.e. mp3, aac, wma, etc from your mobile these eraphones will show them up. a decent source, huawei mobile in HWA mode with the fiio btr3 using flac files or hi res streaming, sony walkmans, fiio dap's or a&k ones or a home hifi vinyl in particular then be prepared for an amazing experience.
