The CL in Harman Kardon's CL headphones stands for "classic." That's because great sound never goes out of style, and the CL headphones bring it right to your ears in a comfortable, modern package. The black matte housings and steel headband give these on-ear headphones a striking designer look — but not at the expense of sound quality. The CL's bass response is augmented by tubes in the earpieces that function similarly to the port in a speaker cabinet, as well as a unique driver baffle designed to extend low frequency response. So you'll hear all the dynamics and details of your music, from the bass guitar's bottom end to the sizzle of the cymbals.
Extra attention to comfort and fit
Harman Kardon went the extra mile to ensure the CL headphones fit just about everyone. The soft memory foam earpads rest snugly against your ears for comfort that lasts. Durable steel hinges allow the earcups to swivel in two directions and automatically adjust to the shape of your head. The CL even comes with a second larger metal headband bow, which allows you to swap out the preinstalled bow if it's too small to provide the comfort and security you need.
In-line remote and mic for iPhone® and iPod®
The CL headphones feature a three-button remote for track and volume control with Apple devices. Skipping songs and cranking them are easier than ever, even when your iPhone® is in your pocket. And the remote's built-in microphone gives you the freedom of hands-free phone conversations. Plug the CL headphones into your iPhone and you're ready for great-sounding music and clear calls wherever you go.
From our Harman Kardon CL and BT headphones review:
While up-front, the bass was tight and nicely defined, not loose or boomy. It felt more natural, just emphasized. The CL's midrange that impressed me the most. It's smooth, natural-sounding, and not at all recessed. Vocals sound beautiful and stand out nicely.
