The Adapt Bluetooth Headphone Adapter from Outdoor Tech is slightly misnamed. It doesn’t just work with headphones and earbuds; it can work with any speakers or device with a 3.5mm audio-in jack. When you use it with your headphones or earbuds, convert your standard headphones into Bluetooth gear. Simply clip the adapt to your clothing, and you can listen to music or take phone calls while your phone stays safely in your pocket or bag. You can shorten up your cord so that your arms don’t get tangled up or so you don’t snag the cord on things as you pass by. The built-in microphone has noise reduction and echo cancellation for clear calls. The rechargeable lithium-polymer battery gives you 5-6 hours of playback or 150 hours of standby between charges. The buttons on the Adapt allow you to control playback of your audio source or to answer calls. It has A2DP Bluetooth profile for high quality stereo sound streaming and AVCRP to control track and volume remotely; it pairs and reconnects easily with your phone. It has the same rugged, rubbery coating used in many of Outdoor Tech’s line, and it’s available in black, blue, pink, orange, or yellow for $39.95.
