No sound - but possible to have sound if desired. It is a RGB LED, pretty sure that Arm on Fire said it was an OPP (the one VV uses). At the same time, it is used with a quick connect, so I asked for a p4 Led and a purple/RGB led, which I can then change it whenever I want.
- Yes, it is SUPER good for spins, I can also use a set screw which would prevent any damage to my hand from the thumb screw. Spins/grip/handle is amazing.
