Jabra's M5390 is an enterprise-class Bluetooth headset. Priced at Rs 20k, it comes with a USB adapter for PC connectivity, but can also work with any Bluetooth-equipped devices like cellphones. But there are reasons why it's so expensive.rnFirstly, it can be paired with 8 devices at a time. Of those 8, it can be connected to two devices simultaneously. Secondly, when used with the supplied USB dongle, you can get an extended range of upto 70m (in free line of sight). A standard Bluetooth connection usually has a range of only 10m.
