Otto has been making communication gear for racing car teams, law enforcement and fire fighters for years, but here's one of its first consumer products - noise-cancelling headphones with a built-in MP3 player.

The Traveler n/c cans are pretty standard, offering 85 per cent noise reduction (20dB active, 7dB passive) and 20Hz to 20KHz response through an on-ear design.
