Package Content & Design
As usual, my SpinFit CP240 is a sample. Therefore, no retail packaging to show here. As for sizes, there are L, M and S. So far, CP240 is the only model for double flange. You can also check out other SpinFit single flange models at their website including CP100, CP100Z, CP145, CP155 and CP800. Refer their sizes and compatibility there.

For your information, SpinFit uses premium silicone which last longer than foam type tips. Rest assures that its durability will last for long.

Here are the inserts (adapters) which has 3 mm nozzle (core) dimension. Yes, it can support small bore earphones with these inserts. About the same as CP800 on single flange. Note – the standard one is 4mm like CP100.

Fit, Comfort & Isolation
Yes, you can get even deeper and better seal with double flange – SpinFit CP240 compare to their single flange models. And still getting pleasant and comfort to wear for long hours. Again thanks to SpinFit patented 3d axis unique design – 360° rotation. This special designed cushion at the centre of the shank allows it to rotate freely 360°. And this make it can go deeper into your ear canal and seal better according the shape. As a result, better isolation too.

Sound Quality
Ear tip is one of the important parts of in-ear monitors. You are not getting the most out of your IEM when not getting proper seal and fit. The best and easy way to enhance and improve your earphones is getting your best matched tips. SpinFit CP240 manages to get even deeper and better seal compare on original bundled eartips. This result in more bass and isolation. Less fatiguing on very bright treble too. Of course, you won’t get day and night improvement but definitely there is marginal one.

SpinFit CP240 surely improve overall listening experience. And do take note that different earphones and tips yield different results.
