A Serious Listen: Astell & Kearn: AK T1p headphones These Astel & Kern AK T1p ($1199) cans are among the most beautiful, striking designs around; an artsy, pristine piece. Beautiful brushed metal, luxurious comfortable pads, lightweight, produced by a partnership between A&K and beyerdynamic. This is a worthy sight on anyone's head. Smaller in diameter than my reference Audeze LCD-X, but still circumaural. Each A&K phone is hand-made, individually serialized: I'm reviewing #335.
