Product Description
Sound by KEF. Design by Ross Lovegrove.
The KEF Mu7 Noise Cancelling Over-ear Wireless Headphones deliver premium sound quality
coupled with the ease of wireless listening. For these extraordinary headphones, KEF has once again
collaborated with visionary designer Ross Lovegrove; a relationship that started with the incredible
Muon loudspeakers, through Muo Bluetooth speakers and now the Mu headphones. Tuned by the KEF
engineering team, Mu7 delivers pristine, high-resolution sound on the go, and thanks to Smart Active
Noise Cancellation and intuitive controls you’ll never miss a beat.
KEF’s signature pure and accurate sound
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. In each of the curvaceous closed-back earcups sits a 40mm full
range dynamic driver, the diligent design and tuning of which has been undertaken by our engineering
team. The result is an incredibly engaging listen, where each and every aspect of your favourite music is
delivered in a pristine performance.
All day, any way
Smart Active Noise Cancellation
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. It focuses the processing on the relevant frequencies and
automatically adjusts the noise cancellation to be much more effective and makes the listening
experience unique depending on the surroundings. Smart Active Noise Cancellation provides a major
improvement over standard one-size-fits-all versions, ensuring that your noise cancellation experience
is consistently effective and never gets in the way of the music.
All-day listening experience
The Mu7 frees you from the tyranny of 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. There is also a 3.5mm audio connection if a wired
connection is preferred and for those who want to unlock the uncompressed high-resolution playback
from their compatible phones and dedicated headphone DAC/amplifiers.
Comfort and ease
Ergonomic design
Mu7’s precision-engineered aluminium construction is the result of in-depth analysis to develop a
design that provides the highest level of comfort to most people. Strong, lightweight and durable, KEF’s
engineers have ensured that the headband’s clamping force delivers an ideal acoustic seal, but without
placing too much pressure on your ears.
The leatherette memory foam ear pads mould to the shape of your head, creating a comfortable seal
that helps shut out external noise, improving both passive and active noise cancellation and bass
response. A clever swivel point just above the earcups allows the Mu7 headphones to be rotated to lie
flat, perfect for storing in carry-on luggage, a briefcase or the pouch that comes in the box.
