Strong, well-defined bass with good texture. Delivers satisfying punch and rumble without overwhelming other frequencies.

Excellent midrange with natural timbre and great detail retrieval. Vocals are forward and emotive with lifelike instrument reproduction.

It's a solid set, with great build quality, but sonically isn't the specialist that I want it to be.
