What reviewers say

Secrets of Home Theater and Soomal praise clear, refined sound and a spacious presentation. Secrets particularly liked their automatic fit, comfort and binaural imaging. Soomal found leaner mids, limited impact beside modern flagships and pronounced sensitivity to the source; it cautioned that its ageing sample may not represent every surviving pair.
