Our rentals headphones will arrive fully charged and have a battery life of 8+ hours. For long events, we recommend not powering on the headphones until you're ready to use them.

If you have a weekly or monthly rental contract, chargers will be included in your package so you can keep the batteries full between days of use. Chargers can be provided on 2-day rentals if requested. 

Each charger can charge to 16 headphones at a time on a single standard 120V power outlet.  It can take 2-4 hours to fully charge a completely empty battery.
