We tested this feature extensively and found that it was incredibly easy to pair IOGear's Wireless Bluetooth Stereo Headphone Kit with our test cell phone, a black Motorola Razr. Once we did this, the headphones performed admirably. We were able to switch effortlessly between cell phone conversations and the music coming from our MP3 player. The only problem is that the included mic has to be connected to the headphones in order for you to talk on the phone. That means you'll need to leave it attached all the time (bent away from your face) or grab it from your pocket and connect it every time you want to answer a call. A better implementation would be a telescoping mic, as found on the .
Sound quality on the IOGear Wireless Bluetooth Headphone Kit is good, with surprisingly deep bass and no hiss whatsoever, but the rated battery life of 6.5 hours is pretty lame. Recharging headphones is not an instinctive activity. Another issue we had was that the Bluetooth transmitter sometimes disconnected slightly from our MP3 player's headphone jack when we jostled our bag around, cutting out one channel of audio. Since this device is designed for use on the go, this is worrisome.
All in all, we were impressed by the way these headphones do away with the hated headphone wire and work so seamlessly with a Bluetooth-enabled cell phone. If you talk on the phone a great deal, love listening to music on the go, have enough disposable income to justify spending $180 on a headset, and don't mind securing the transmitter to your MP3 player to avoid music dropouts, the IOGear Wireless Bluetooth Headphone Kit is a good purchase. For the vast majority of users, though, it's more of a taste of exciting developments to come, as portable Bluetooth headphones improve, MP3 players evolve to support them more seamlessly, and the price drops.
