There are many reasons why Bluetooth is a good choice as a medium
for wireless stereo headphones. The Advanced Audio Distribution Profile
(A2DP) of which Bluetooth wireless headphones use, delivers surprisingly
good audio quality. The roaming range of Bluetooth headphones from a
transmitter is good (up to ~20 ft). Perhaps most importantly, because
Bluetooth technology has already achieved global acceptance, compatibility
between varying adapters and headphones is fairly high. The latter reason
is particularly important because it allows the possibility of portable
media player manufacturers to incorporate Bluetooth into their devices;
therefore, they can connect to any Bluetooth headphones sans an additional
external adapter. Such devices are already in the market. Almost all of the
latest cell phones that support Bluetooth as well as media playback
(smartphone or not), can be paired with Bluetooth headphones for high
fidelity wire-free music enjoyment.
