Harman Kardon (http://www.harmankardon.com) has released several new headphone models.

The in-ear model NI (US$99.95) features 9mm drivers to provide a wide-dynamic range and high sound-pressure levels. This ultra-light model has a rectangular black housing -- shaped like the back of an iPhone -- and a 3-button remote with a built-in microphone for calls. It comes with three sizes of silicon sleeves.

The in-ear model AE ($149.95) acoustically enhanced headphones isolate noise and is enclosed by a silver-toned aluminum casing for superior acoustic dampening. The headphones include premium 9mm drivers optimized to work with the metal housing to deliver extended bass response. A 3-button remote with a built-in microphone is included, while foam sleeves are offered along with three sizes of silicon sleeves. 

The on-ear model CL ($199) are defined by precision with metal hinges, a sand-blasted metal finish and rectangular ear cups that reflect the iPhone’s iconic design. The 40mm drivers are baffled to create an air flow that extends the low frequencies -- bass -- better than other models in its class. The detachable cables feature finished metal connectors, while the cables are made of a tightly woven fabric to enhance feel as well as durability and flexibility.
 
The over-ear model BT ($249) Bluetooth headphones include an integrated microphone so users don’t have to remove them for a call. Built-in playback buttons sit along the side of one earcup for easy music controls. These high-performance wireless headphones are charged via included USB cable, but also work in passive mode. That means if the battery -- which lasts 12 hours -- is dead users can attach the fabric-covered headphone cable for wired playback from an iPhone, iPod or iPad.
