The VMK15 does have a factory reset. Hold the volume buttons Vol+ and Vol- down at the same time for about five seconds, and that is it. If you once read from us that there is no reset, that information was wrong. It has been fixed, and this is the correct instruction.
A reset is worth doing when the headphones behave erratically and the battery is not the culprit. It will not fix a mechanical fault and it will not charge anything, but it does clean up Bluetooth mayhem.
When a reset is worth doing
- The headphones stubbornly connect to the wrong device
- The headphones do not show up in any Bluetooth list
- Multipoint is confused: the sound comes from the wrong device, or from none
- The buttons do not seem to obey
- The sound stutters even though your phone is in the same room
How to reset the VMK15
- Make sure the headphones have power. If the battery is completely flat, charge them for a while first with an ordinary 5 V / 2 A charger.
- Find the volume buttons on the left ear cup. All the VMK15 buttons live there, and you can tell the left side even in the dark by the raised dots on the headband.
- Press Vol+ and Vol- at the same time and hold them for about five seconds. Then let go.
- Remove "Valco VMK15" from the Bluetooth settings of all your devices. All of them, including that work laptop you forgot about.
- Turn the headphones on by holding the MFB button for about three seconds, then keep holding for another three seconds. The headphones go into pairing mode.
- Select "Valco VMK15" from your phone's Bluetooth list. If it asks for a PIN, it is 0000.
Clearing the old pairings from your devices is not pedantry. The headphones have forgotten them, but your phone has not, and a half valid pairing is the most common reason a connection still refuses to work after a reset.
What the reset actually does
It wipes the Bluetooth pairings. The headphones forget every device they have ever connected to and start from a clean slate. That is all it does: the firmware stays put and the PIN is still 0000. If some guide promises that a reset clears anything else, that guide is made up.
If the reset does not help
Check the ANC first. On the VMK15 it is a plain on/off switch, not a software mode, and there is no transparency mode at all. Press the button and you hear a beep, and a green light inside the ear cup tells you the noise cancelling is on. If the light is on but you hear no cancelling, it is usually about fit: on-ear pads need to sit snugly against your ears.
Next, charge the headphones for at least half an hour with an ordinary 5 V / 2 A charger, not a fast charger, and try again. In the meantime you can listen with a cable, because the VMK15 has an AUX socket too.
If the headphones still refuse to cooperate, it may be a hardware fault. Send a message to info@valco.fi and tell us your order number, what is happening and what you have already tried. The warranty is 24 months. Even after that, a repair costs a fixed 69 euros including spare parts and shipping both ways, and a repaired pair gets another year of warranty on top.
