Bluetooth is one of those magical technologies whose
implementation seems to have been totally mucked up by the bureaucratic red
tape of interoperability. In theory Bluetooth is a close
range wireless data transmission standard that enables any number of
devices to share data.. Bluetooth has modest bandwidth so it's not like
WiFi, rather it can be thought of like the wireless equivalent of USB; it's
good for peripherals, to a range of about 10 meters. The closest
you've likely come to Bluetooth is turning off the blue light on a notebook because
it's never used, or seeing a male aged 18-34 walking around with a silly looking
silver Star Trek like device on one ear that blinks bright blue every few
moments. That's a Bluetooth headset for a cellphone.
Bluetooth devices make connections in a process called 'pairing',
ensuring that only approved connections are set up between your cellphone
and headset, or laptop and cellphone, for example. There are two main reasons, 1)
viruses and 2) retaining control of your Bluetooth enabled devices. Pairing
isn't complicated, but getting there can be quite convoluted. If you're willing
to get your hands dirty by thumbing through the user manual,
Bluetooth will offer up its cable free features.
For mobile phones the prime Bluetooth application is the
hands free headset - a safety measure when driving and hedge against the
undetermined affects of cellphone radiation to your noggin. Being the trendy
company that it is, Samsung
has clued into one other useful application for
Bluetooth - stereo streamed music from an iPhone or any MP3-enabled phone to
a stereo headset.

Most cellphones offer MP3 playback of some degree,
and some MP3 players offer integrated Bluetooth connections, so it only makes sense
for Bluetooth headsets to evolve from the monophonic devices that hang of a single ear
into a pair of which offer stereo sound.

recharging the integrated 150mA Li-polymer
The Samsung Bluetooth Stereo Headset (YA-BH270) looks like a regular pair of over-the-ear
headphones, except there's no audio cord to plug into anything.
Samsung's YA-BH270 works off a rechargeable integrated 150mA lithium polymer
battery that gives you between 6.5-8 hours use. In standby mode the headset
remains active for about a week on one charge (or 240 hours), the battery is
charged in about 2 hours via USB cable.

Left hand earphone
has controls for menu, play/pause, and call
off-hook. The headset microphone is for making calls. A

The YA-BH270 is a
pretty simple device, so no software required. The manual quickly outlines how to
pair the unit with another Bluetooth enabled device, and covers
the compact array of buttons which festoon the left-hand ear piece.

Along with standard audio-centric buttons for advancing through MP3 tracks or
adjusting volume there is one special key for making voice-activated calls.
