8 balanced armatures per ear, amazing sound. Cable is made by TRN and is Bluetooth 5.0 with AptX support. This cable has MORE than enough power for these IEM's, seriously, I was expecting sort of paltry sound considering how much power these IEM's need but this cable has no issues. Easily the loudest wireless headphone I've owned and I've a LOT.

I've also added magnets to the back of the IEM's then covered them in leather and added magnets to the cable so you can stick the IEM's out of the way and not have them just hang down. Looks good, works well, nice addition.

I can include tips if need be as well if you don't have some already, they might be a bit random. Let me know your size.
