Refurbished VMK20 Noise Cancelling Headphones
Originally we tried to stay alive by reselling warranty returns from a spectacularly nasty chip defect back to customers. Turns out people are actually pretty happy to buy used headphones at a discount, as long as the warranty is still valid.
You can now trade in your used VMK20 headphones with us and get a reasonable credit toward a new pair. We take these headphones in, repair them, clean them, service them, make sweet love to them, and put them up for sale right here, just for you.
Warranty-serviced units go up for sale at whatever pace Hannes manages to fix them, so if we're sold out right now, check back in a few days.
Colour options pop up pretty randomly depending on what comes in as trade-ins. If you really want a specific colour, you're better off ordering a new pair here.

Great products without the dead weight*
Did you know that almost all the electronics inside headphones come from a handful of giants?
Everything else is just smoke and sales talk.
A small maker like Valco can use the exact same top-tier components as the famous mega-corporations stick in their pricier models.
We just don't have a thousand employees to feed, a Manhattan skyscraper to pay for, or a CEO with a private jet (yet).
Which is why we can give you the best bang-for-buck on the market.
And what happens after you've bought? Our customer service and Valco's in-house repair team make sure our products last. And if you fancy a change, you can trade your old Valcos back in to us. Try doing that anywhere else.
At the end of the day, the point of all this is simple. We sell headphones to fund our own Death Star, so we can rule the galaxy.
