KEF is finally stepping into Sonos territory with a portable speaker that doesn’t mind getting wet. The new KEF Muo packs IP67 waterproofing, a compact build, and promises 24 hours of playtime. That puts it in direct competition with the Sonos Roam, but it’s missing a couple of essentials that might make or break the deal for some.
KEF Muo speaker brings long battery life and portability
Shiftdelete.netAt 8.5 x 3.2 x 2.3 inches, the KEF Muo is slightly bulkier than the Sonos Roam 2, but in exchange, it offers a standout 24-hour battery life. That’s a serious upgrade over many speakers in its size class. The IP67 certification also makes it fully waterproof and ready for poolside use or sudden downpours.
KEF has packed in solid audio hardware too: a 20 mm tweeter, a 58 x 117 mm woofer, and two amps (10-watt and 30-watt) drive the sound. The Muo can hit up to 90dB and covers frequencies from 43Hz to 20kHz. It even supports aptX Adaptive, which should help deliver decent Bluetooth sound quality.
TSMC N3P price increase hits Qualcomm and MediaTek harder than Apple, raising flagship chip costs and possibly smartphone prices next year.
It skips WiFi and wireless charging
Here’s where things get dicey. Unlike the Sonos Roam, the KEF Muo doesn’t support WiFi. That means no AirPlay, no multi-room audio, and no streaming over your home network. You’re stuck with Bluetooth or USB-C. For some users, that trade-off might be fine, but it’s a definite step back in terms of home integration.
Charging is another cut. KEF skips wireless charging entirely. That’s surprising in 2025, especially when it’s aiming for premium territory.
What the KEF Muo speaker does right
Still, the KEF Muo isn’t without smart touches. You get stereo pairing with a second unit, hands-free calling support, and access to the KEF Connect app for EQ tuning. These features give it a decent edge over barebones Bluetooth speakers in its class.
Highlights of the KEF Muo:
- IP67 waterproof rating
- 24-hour battery life
- aptX Adaptive Bluetooth audio
- Stereo pairing supported
- Hands-free calling via Bluetooth
- Custom EQ through KEF Connect app
This speaker feels built for the outdoors, not the living room
KEF’s new Muo is clearly tuned for on-the-go listening. It’s rugged, long-lasting, and sounds promising on paper. But the lack of WiFi and wireless charging is hard to ignore, especially when Sonos delivers both out of the box. The Muo might win in battery life and portability, but it bows out when things move indoors.
