Sony has added to its line-up of Bluetooth earphones with the launch of the DR-BT101 noise-cancelling cans.

The earphones allow users to listen to music without an annoying cable getting in the way, but are also being pushed as an option for enjoying clearer, more convenient VoIP calls or taking calls on your Sony-branded phone.

In fact, Sony is offering two versions of its new Bluetooth v2.1 headsets, the DR-BT100CX earphones and the DR-BT101 headphones.

Both let you enjoy the music on your mobile phone or MP3 player (or another suitable Bluetooth-enabled device within the technology's 10 metre range) and can control audio playback via a mini remote control as well as accepting or rejecting incoming phone calls.

The BT101s have a 30mm neodymium driver and can operate for up to 12 hours before needing to be recharged via a USB connection on a PC or laptop. A2DP, AVRCP, HFP and HSP Bluetooth profiles are supported. The BT100CX earphones have 9mm in-ear drivers suitable for more discreet listening.
