Intuitive control
KEF’s engineers understand that control is vital when using earphones, which is why the Mu3
earphones feature a highly intuitive, incredible responsive user interface. And because we know you
may be doing other things while you listen to music, each of the earbuds includes a multi-function
button for full control of music playback, volume and calls for instant control when only one hand is
free.
Design by Ross Lovegrove
Renowned for his innovative approach and flowing, sculptural forms, Ross Lovegrove brings a new
dimension to sound. Through design that embraces both beauty and technological ingenuity, Lovegrove’s
ongoing collaboration with KEF is an exercise in aesthetic and engineering excellence.
The Mu3 earphones may be small, but they radiate a sculptural look and feel that belies their compact
dimensions. The collaboration with Ross Lovegrove has once again resulted in a product that is the very
definition of technology as art, and a design that smartly complements the KEF philosophy.
