What reviewers say

Reviewers agree it sounds clear, full and detailed, stays clean at high volume and is rugged, with long battery life. TechRadar and Trusted Reviews find it pricey; they differ on the default tuning, which TechRadar found light on bass and Trusted Reviews a touch too bassy, and What Hi-Fi? regrets the lack of a microphone for calls.
