Description:
The Losei BT-K2 has pretty respectable battery specs for a cord-free Bluetooth headset, as evidenced by its 2-to-4-hour talk time and 120-hour stand-by (both on a single charge) -- having the capacity to extend further by using the 450mAh charging box.
Also known as Losei True Mini K2.
