SpinFit - CP240

Great fit and sound quality. I only wish they came in Black Color, but that's not a deal-breaker in any way. Thanks HPZ for the super fast and efficient delivery :)

if you understand how to use it, you will get the best out of it. First I ended up almost squeezing it and locking inside my ears (LOL). The trick is you need to just establish the correct positioning with the ear tips, i.e. insert it a bit deeper later lightly pull back don't fully pull out. Keep playing music while you are doing so when you hear the best output from the ear tips while positioning the ear tips - that the spot(wink).

For sound isolation and quality. Build quality is also great.

I regularly use a comply small size ear tip on a fiio f9 pro, so my observations are relative to that ear tip. I got a small size spinfit and now I feel I should have gotten the medium one. Sound isolation is poor, probably because of a looser fit (cannot confirm unless I try a medium size). The treble gets highlighted and the bass gets muffled probably because of the same reason.
It is extremely comfortable, for which I would definitely recommend it. I'm going to keep it as the life of comply is so short and rather unaffordable in the long term.

Purchased these for my F9 pro. Fits great in the iem. Listening experience is more detailed while using this. Can experience more punchy bass, now, the pinchy treble peaks are more gone so the details are more enjoyable.
Superfast delivery by HPZ as usual. You guys are the best in the business.

Very good fit with my Fiio f9 pro. The sound quality has improved a lot over a single flange tip. The thinness is gone. The bass has improved and became tight. The mids are very good. The sparkle in treble region is controlled. Overall very good tips. I would suggest this tip over a regular single flange tips any day.
