Digital Age Walk-Free Wireless USB Headphones
 

Hi, we just completed a review of probably one of the first Wireless USB headphones review. Such headphones replace the audio sub-system on your PC. They are kinda like typical USB headsets except this pair uses a simple USB dongle that boosts 2.4Ghz wireless frequency for audio transfer. A tapered headphone design includes an adjustable and comfortably padded set of earphones that work off of two "AA" batteries (included). The headphones also include a built-in volume control dial. The USB transmitter includes a Blue LED signal indicator that lights up to show power and signal strength.
