Wireless Gaming Headsets

Two things separate a headset from headphones

Gaming headsets are separated from music headphones by two things: a boom microphone positioned near the mouth rather than in the earcup, and a low-latency mode that narrows the gap between picture and sound.

Where a listing names a dongle or a 2.4 GHz connection, that is the low-latency path. Standard Bluetooth is the compatibility path, and they are not the same link.
