A Japanese consumer electronics company called Logitec (note: unrelated to "Logitech") will be releasing some Bluetooth headphones specifically for use with the PSP.
They're certainly not the first Bluetooth headphones for the PSP, but they are the latest. More details inside!
Features:
Includes PSP adapter (powered by 1x AAA battery)
Designed to fit PSP
One-touch connection with PSP
Acts as PSP headphones and mobile phone/PC headset (simultaneously, even)
Specifications:
Bluetooth 1.2 (A2DP, AVRCP)
Integrated microphone for simultaneously pairing with your PC/mobile phone (HSP, HFP)
White or black body colors
Dual pairing -- easily switch between PSP and mobile phone
Phone call rings heard through headphones; one button push to pause music and answer call, one more to end call and return to PSP audio
Lightweight, open-air design
10 meter range
Impress Watch estimates a 12,800 yen (~$110 USD) price tag. After purchasing some Bluetooth headphones a couple months ago (from "Logitech" even), I must say eliminating wires is always awesome. The only other features I could really ask for in PSP Bluetooth headphones would be integrated/rechargable batteries and some sort of support for controlling the PSP itself (to skip tracks and such).
