Jabra's introduced their BT620 Bluetooth stereo headset, which'll let you automatically switch from listening to music to answering a phone call. If you're listening to music when a call comes in, the headset will just pause tunes and give you the option to answer the call or ignore it. Also, the BT620s can connect to two devices, so you don't necessairly need to have a cellphone with MP3 capabilities to use them. Jabra says they'll give you about 16 hours of talk time or 14 hours of music streaming on a single charge (recharge time is about 2 hours). Retail price is $129. Jabra also announced the BT325, BT160, and the JX10, all of which are Bluetooth devices and go for $99, $59, and $179 respectively.
