| Bottom line | Despite a few shortcomings, TDK's WR700 wireless headphones--which use Kleer wireless technology instead of Bluetooth--deliver good sound for a reasonable price. | The AKG K 830 BT headphones offer a simple wireless solution for music lovers sick of tangled headphone cords, but the underwhelming Bluetooth audio fidelity isn't worth the overambitious price. | If you're sick of tangled wires, the Creative WP-350 model is one of the better-sounding Bluetooth wireless headphone sets for the money. | The Creative WP-450s are good Bluetooth wireless headphones, but the step-down WP-350 model is a better deal. | Sennheiser's affordable, comfortable wireless headphones sound almost as good as corded 'phones. |
