Image © KEFThe KEF Mu7 are over-ear wireless headphones with adaptive noise cancellation and a robust 40-hour battery life, even with ANC active. They offer broad codec support including aptX HD, multipoint Bluetooth 5.1, and a comfortable build, though sound character and feature set may divide opinion. Their performance leans toward a neutral, hi-fi presentation, but they lack some modern conveniences like transparency mode or EQ adjustments. Overall, they're a solid, if not class-leading, option for long-listening sessions with adaptive ANC.
