Most commonly it is used to pilot a radio-controlled aircraft or other type of unmanned aerial vehicle (UAV) such as a military drone. The operator gets a first-person ...
These systems often also implement Headset (HSP) or Hands-Free (HFP) profiles for telephone calls, which may be used separately. Each A2DP service, of possibly many, is designed to uni-directionally transfer an audio stream in up to 2 channel stereo, either to or from the Bluetooth host. [2] This profile relies on AVDTP and GAVDP.

In 1957 Willard Meeker developed a working model of active noise control applied to a circumaural earmuff. This headset had an active attenuation bandwidth of approximately 50–500 Hz, with a maximum attenuation of approximately 20 dB. [3] By the late 1980s the first commercially available active noise reduction headsets became available.
Simplified graphical depiction of active noise reduction. To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control.A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds.
