The Motorola S705 SoundPilot is a wireless Bluetooth stereo headset that can stream music via any A2DP compatible mobile phone or music player. The S705 doubles as a hands-free headset, has an FM radio and features a small display that shows caller ID and music track information.

A2DP stands for Advanced Audio Distribution Profile and is a technology that lets devices stream stereo sound via Bluetooth. Connecting the S705 SoundPilot is simply a matter of pairing it with your phone, like you would a Bluetooth device. The S705 connected successfully and remained problem-free.

A small display on the S705 lists current track, and also provides feedback on battery charge and Bluetooth status. The four-way navigational stick used to control the headset may be difficult to control for those with large fingers. A call handling button and menu button adorn the right and left sides of the S705 respectively.

When the phone rings, a quick glance at the display reveals the number and name (if in your phonebook). Calls are answered using the call handling button and rejected by the menu button., During a call "on a call" appears on the headset display. The S705 doesn't show missed calls.

When a call comes in while the phones music player or FM radio are playing, the audio is paused. On completion of the call the audio will play again, albeit after a delay of three seconds.

The headset hangs around the neck and the included pair of earbuds of good quality plug into the device. However, one of the best features of the S705 is the standard 3.5mm headphone jack, allowing it to be used with any set of headphones.

The S705's do give off a slight hissing noise during music playback. Apart from this though, the sound is decent without being outstanding. The S705 charges via either an AC adapter or a standard mini-USB cable.

The convenience of music listening and hands-free phone calls in an intelligent device is the primary advantage of the Motorola S705 SoundPilot. While the sound quality isn't all that noteworthy and the unit doesn't come cheaply, the convenience factor will be important for some.
