Yes, we know our MUZIK family likes adventure and travel!
You may use your MUZIK headphone outside of the US when traveling. Just remember to bring the correct power converter based on that country's voltage to properly and safely convert your US USB charger.
In many countries- most in fact, except for the U.S. and Canada, the electrical voltage is 220/240V. Our American devices are designed for 110/120V which is not compatible, even when correctly plugged in through an adapter. You know this first-hand if you’ve ever fried a hair dryer or portable speaker while traveling. This is where the converter comes in.
