BuckbrickHello! The default is for 120V power outlets: -AC Adaptor takes 120VAC 60Hz, outputs 9VDC 1A (14 Watts) -Plug has negative outside barrel and positive signal inside barrel.

Options for 220V power outlets:
1. You can use a step down converter if your global voltage is 220V. 2. Or, you may source a 220V power supply. I am looking into the dimensions of the barrel plug and will report back!
BuckbrickGood news- we have worked with Koss to have 120V & 220V options at check-out!The dev team at Massdrop did a lot of coding to add the options and retroactively assign your orders based on location.
If you already ordered: Please go to your Transactions page from your Profile drop-down menu and find your Order. Please check it to see if you have the correct voltage for your country and usage.
If you have not ordered yet: You can now order and clearly select a voltage option at check-out!
Please Note: the wall power supply will now work with the voltage that you choose, but you may need to provide your own small plug adapter to fit your country’s outlet.
