Instead of buying a wireless headset, ATECH’s receiver plugs into your existing headset to turn it wireless. You can switch between your favorite wired earphones or even use the receiver to wirelessly beam music to your car stereo. No more Aux woes! It comes in a small thumb-drive-esque size with simply one headphone jack and three buttons (one for playback and two for volume). What’s great is that the Micro Bluetooth Receiver even charges via the 3.5mm jack, eliminating the need for an extra port!
