VMK20 won't turn on – what do I do?

Updated

Symptom

VMK20 headphones won't turn on even after charging. The power button doesn't respond and the LED light won't come on.

Quick Fix

Charge the headphones for at least 2 hours. If they still won't wake up, do a cable reset: plug a 3.5 mm AUX cable in and pull it back out.

Your VMK20 is lying on the table like a knocked-out lumberjack and nothing will wake it up. You've tried the charging cable, mashed the power button, and maybe thrown in a few choice words. Take a breath – this is usually an easy fix.

Why won't the VMK20 turn on?

The most common reasons are surprisingly mundane:

  • The battery has completely drained – If the headphones have been sitting unused for a while, the battery may have drained to absolute zero. In that case, they need a longer initial charge before they'll agree to power on.
  • The charging cable isn't properly connected – The USB-C connector looks like it's in place, but the contact isn't quite there. Especially if there's dust or lint in the port.
  • The software has frozen – Rare, but possible. The headphones' internal software may have crashed.

How to fix it

  1. Charge for a good while – Plug the headphones in and leave them alone for at least 2 hours. Don't try to turn them on in between. If the battery is completely dead, the headphones won't show any signs of life for the first 15 minutes.
  2. Check the charging cable – Try a different USB-C cable and a different charger. Carefully clean the charging port on the headphones with a toothpick or compressed air.
  3. Do a cable reset – Plug a 3.5 mm AUX cable into the headphones and pull it back out. That is the VMK20's own reset method and it clears the Bluetooth circuit. Then press and hold the power button until you hear the tone.
  4. Try charging from a computer – Sometimes a cheap charger doesn't deliver enough power. A computer's USB port provides a steady current that's enough to wake up a dead battery.

If nothing works

If the VMK20 still won't wake up after 2 hours of charging and a cable reset, it could be a battery fault or another hardware issue. Get in touch with Valco customer support – let us know when the headphones last worked and what you've already tried. We'll sort it out.

Headphones are a bit like cats: sometimes they just decide not to respond. But unlike with cats, there's actually a solution for this.
