Due to initiatives to allow blind users to use computers, there are operating systems which allow fairly-complete use with audio only. Since headphones are relatively inexpensive, the cost of audio-based wearables is quite low, and this makes audio-based wearable computers a lucrative "first step" into wearable systems.

Unfortunately, since many enthusiasts of wearable computers spend a lot of time building nice video rigs (such as head-mounted displays), there is little documentation of audio rigs. This is a wiki: If you have any documentation, please add it!

Bone conduction earphonesEdit

Some hearing aids employ bone conduction, achieving an effect equivalent to hearing directly by means of the ears. A headset is ergonomically positioned on the temple and cheek and the electromechanical transducer, which converts electric signals into mechanical vibrations, sends sound to the internal ear through the cranial bones.

Bone conduction products have following advantages over traditional headphones:

  • Ears-free, thus providing extended use comfort and safety
  • High sound clarity in very noisy environments, can be used with hearing protection
  • Can have the perception of stereo sound

There are some disadvantages:

  • Some implementations require more power than headphones
