How does Muo compare to other Bluetooth speakers?

Does a speaker this small still produce powerful bass?

Delivering powerful, controlled bass from a compact speaker was a key focus for our engineers. They achieved this by combining a unique large racetrack driver with our P-Flex Surround, a technology adapted from our flagship subwoofers, to ensure the hardware can produce deep, articulate notes.

This performance is then intelligently managed by our Music Integrity Engine® (MIE). It uses bespoke algorithms borrowed from our flagship LS60 Wireless speakers to ensure the bass is always powerful, yet perfectly balanced and controlled, even at high volumes. The result is a surprisingly deep and musical bass performance that you can truly feel, all from a speaker you can carry in one hand.

What does the IP67 waterproof rating actually mean?

The IP67 rating means Muo is fully dust-tight and protected against immersion in water up to 1 metre deep for 30 minutes. If you've been using it in heavy rain or it takes a splash, you might notice a temporary change in sound if water gets in front of the speaker drivers.

This is completely normal, so there's no need to worry. Simply let the speaker air-dry completely, and it will return to delivering the full, fantastic sound you expect from KEF.
