VMK25.2troubleshooting and user guides
Valco's best noise-cancelling headphones
About this product
VMK25.2 — because inflation is a choice and a mistake needed fixing.
Can you improve on excellent? At Valco, we say yes. The VMK25 was a success, but we made a small technical blunder: our cheaper model (the VMK15) was accidentally too advanced. The order needed restoring.
We took everything good about the original VMK25 and upgraded the internals: new Qualcomm Snapdragon S3 chip, 55 hours of battery life, improved ANC. The price stayed the same, because we figured inflation is more of a mindset than a law of nature.
No blinking lights, no unnecessary gimmicks — just pure Valco at its best.
