On November 19, Audio-Technica announced the first product in their new PREMIUM COMPACT line, the ATH-CKN50. What's notable about the CKN50 is that it is the first Audio-Technica product to utilize a 5.7mm driver, the smallest the company has ever produced. It also utilizes the a new circular version of the loop support system, dubbed "Next Loop-support Structure" or N.L.S. for short. This, combined with the small size of the housing, is said to improve fit. Curiously, the 1.2 meter cable is an asymmetric design, a rarity for Audio-Technica.
