You press the power button and wait for that familiar startup sound. Nothing. The red light is flashing like an ambulance siren, and the speaker just sits there on the table like a burnt-out charcoal briquette. Don't panic – this is usually an easy fix.
Why is the MK3 flashing red and refusing to cooperate?
A rapid red flash usually means one of two things:
- The battery is completely drained. If the speaker has been sitting dead for a long time, the battery can drop so low that the device can't muster the energy to start up. It tries, flashes frantically, and gives up.
- The firmware has tied itself in a knot. Electronics do this sometimes. The software gets stuck in a state it can't escape without help. Like a Windows blue screen, but red and in a smaller package.
How to fix it
1. Give the speaker a proper charge
- Plug in a USB-C charging cable and let the device charge for at least 2 hours before you try turning it on.
- Preferably use the charger's own cable, or at least a decent USB-C cable. The cheapest cables don't always deliver enough power.
- During charging, the red light stays on steadily – that's normal. When the battery is full, the light turns off.
2. Do a factory reset
- Press and hold the M button for 10 seconds. Yes, ten seconds feels like a long time. Count out loud if it helps.
- Let go and try turning it on normally with the power button.
- This resets the speaker's settings and Bluetooth pairings. You'll need to pair your phone again, but that's a small price to pay for a working speaker.
3. Try a different charger and cable
If the device doesn't respond to charging at all, the issue might be the cable or charger. Give another USB-C cable and another charger a go. The MK3 supports 5V/3A charging, but it'll start up with less – as long as it's getting some power at all.
4. Charge and reset combo
- Plug in the charging cable.
- Hold the M button for 10 seconds while the charging cable is connected.
- Wait a minute and try turning it on.
This combo helps in situations where the battery is so dead that the device can't even reset itself without external power.
If nothing works
If the speaker won't come back to life after all of the above, it's most likely a hardware fault. These things happen – electronics will be electronics.

Our repair team in Kajaani will take a look at the device and fix it up. We repair headphones and speakers here – we don't chuck them in the bin. During the warranty period (24 months), it's all sorted free of charge.
And if your MK3 has survived the bottom of a swimming pool, a stint between a dog's teeth, and three festivals before finally calling it quits – fair enough, it's earned its retirement. But let's fix it anyway.
