The acoustics are custom tuned by KEF engineers to bring consistent voicing on the move, allowing you to hear every note, every word, every detail. Qualcomm® aptX HD technology delivers up to 24bit/48kHz for a truly high-resolution audio experience, where every nuance and subtlety of the recording is revealed in all its glory.

The audio performance of Mu7 benefits from the introduction of the Smart Active Noise Cancellation technology. This sophisticated system uses multiple filters to capture the environmental noise around the headphones and applies a specialised noise cancelling algorithm that targets certain frequencies depending on the type of environment.

The Mu7 frees you from wires thanks to reassuringly stable, latency free Bluetooth 5.1 connectivity. It supports multiple codecs for maximum compatibility and sound quality. A high-capacity, quick-charge battery ensures the Mu7 headphones stay the distance for up to 40-hour use even with Bluetooth and Smart Active Noise Cancellation engaged, with a fast-charging feature that delivers 8 hours of use from only 15 minutes of charging.
