AudioTechnica has your answer inside.

AudioTechnica Corporation will release the "ATH-EC7" earphones, which are inner-ear type clip-ons that allow the adjustment of the angle and position of the housing and ear hanger, o­n July 21st. The price is Open Price, but the estimated retail price is around 12,000 yen. Two colors are to be available: Gun Metallic (GM) and Silver (SV).

In addition to your standard angle adjustment of the arm and housing that block the ear hanger, these headphones now also feature a "Swing Adjust Ear Hanger" that allow adjustment of the angle of the ear hanger and arm itself. This is said to allow position adjustment making for the optimal comfort and sound quality. The weight, not including the cord and plug, is 11g.

Using a 15.5mm diameter unit, the headphones also have a 6 nanometer oscillation board. A Neosium Magnet is used for the driver, said to make clear and intense playback quality. The frequency response is from 10Hz ~ 24kHz. The impedence is 16 ohms.

The cord is made of "Elastomer," with a high elasticity, marking it harder to get tangled. The length is 60cm, and a 1m extension cord is included. Earpads and a transportation pouch are also included. Furthermore, the "ER-40" replacement earpads are also going to be sold seperately.
