Altec Lansing conveniently packs all the controls for the BackBeat 903's call answering and music features onto the left and right earpieces. On the outside of the left earpiece, you'll find a single, relatively large call answer button placed parallel with the ear. A single press of the call answer button picks up incoming calls, while a longer press sends the call to voice mail.
Controls for playing and pausing music are placed similarly on the right earpiece, with an additional switch on the bottom edge of the earpiece for controlling volume and track skip. Holding down the BackBeat's play button for a few seconds engages a bass boost feature that emphasizes lower frequencies, but has a tendency to sound overdriven.
The BackBeat's music controls conform to the AVRCP Bluetooth standard, allowing the headset to communicate remotely with other AVRCP-compatible devices. Popular Bluetooth music devices such as the iPhone and iPod Touch, unfortunately, recognize only the play-and-pause features of AVRCP and are unresponsive to track skip controls using Bluetooth.
The Altec Lansing BackBeat 903 isn't the best-sounding, best-fitting, or best-looking stereo Bluetooth headset we've tested, but it strikes an impressive all-around balance. Calls sound natural and the microphone was sensitive and nuanced enough to prevent us from shouting like a lunatic. Music quality is about what you'd expect from a decent pair of $50 on-ear headphones: an open sound with good clarity, but lacking the dramatic lows offered by over-ear cans and sound-isolating in-ear headphones. But while the sealed-ear design of a headset such as the Sony Ericsson HBH-IS800 offers a more dramatic and private sound, the BackBeat 903 is a better choice for active users who prefer not to be shut off from the outside world.
As the closest competitor to the BackBeat 903 in terms of design, price, sound, and features, the Jaybird JB-200i distinguishes itself with a tapered earpiece design and a thinner cable connection that some may find more comfortable than the Altec Lansing design. When push comes to shove, however, we'll give the advantage to Altec Lansing for its more intuitive on-ear controls.
Altec Lansing rates the battery life of the BackBeat 903 at 7 hours of continuous music playback or talk time. A charging adapter with a lengthy cable and interchangeable prongs for foreign sockets is included.
