The Jabra BT620 was one of the most affordable choices in a roundup of Bluetooth headsets. The BT620 may not be as feature-rich as its competitors, but it has quite an remarkable battery life. It has 14 hours total operation time with a fully charged battery. The reviewer found this model to have great stereo sound quality, although he wasn’t impressed with the unit’s design. This model has added functionality since it can work with 2 Bluetooth devices at the same time. You can sue it for both your phone and a Bluetooth-enabled music player.
