Great sound, clear calls and cutting-edge design, without the wires
Go hands-free and wireless with your music and phone calls with Harman Kardon's BT headphones. Bluetooth connectivity means you can conduct clear conversations without touching your phone. Clever controls on the earcup let you answer calls, hang up, and adjust the volume as you talk, with no dangling cables to get in your way. You can also enjoy music wirelessly from Bluetooth smarthphones, tablets and audio players. The BT's AAC and aptX® encoding provides the finest streaming sound quality available when using compatible devices. Once your music reaches the headphones, you can be sure it will sound detailed and bold. Harman Kardon's design includes bass tubes that function like tuned bass ports, providing extra low-frequency "oomph" to complement the BT's high-frequency clarity.
The Harman Kardon BT headphones come with an optional miniplug cable for passive listening, even when your battery is drained.
Listen even without a charged battery
Bluetooth headphones rely on battery power for wireless streaming. And the BT is no exception, with a USB cable included to enable easy charging from any computer for up to 12 hours of listening. But while some Bluetooth headphones leave you high and dry if the battery is drained, the BT comes with an optional cable for passive listening. So even if you can't charge the battery, you can still plug in and keep the music going. This makes the BT ideal for travel, especially those long plane trips where you don't want to be stuck with headphones you can't use.
Going the extra mile for comfort
These headphones are built for comfort and looks. The unique rectangular earcups will turn heads, while the soft memory foam pads provide comfort that lasts. And we were particularly impressed to see the inclusion of an additional headband. The BT comes with a small headband installed. But if it doesn't provide the comfort and security you need, you can swap it out with the included larger headband. With this level of attention to fit and comfort, the BT should look and feel at home on anyone.
From our Harman Kardon CL and BT headphones review:
The earcup track and volume controls are extremely easy to use without fumbling around trying to figure out which button is which. I must admit, there is something magical about moving about wearing headphones with no cable. If Bluetooth is a priority, the BT is a great choice, particularly if you own an aptX-compatible device.
