Audio Technica ATH-CKX9iS


Needs a bit more refinement, but the ATH-CKX9iS are a solid pair of headphones from Audio Technica

Ingenious design ; Comfortable ; Meaty, detailed sound

Not as easy to put in as conventional buds ; Short on sonic refinement

We applaud the fact that Audio Technica has done something to address the problem of buds slipping in the ear, and those who find this a recurring problem would do well to give the ATH-CKX9iS an audition.

For the £75 RRP, the Audio-Technica ATH-CKX9is SonicFuel headphones are a compelling package with warm, rich sound and a sturdy fit – we’ve got a feeling you’ll be hearing much more of Audio-Technica this side of Japan from now on.
