RockBoard HA 2 In-Ear Monitoring Headphone Volume Controller

The RockBoard® HA 2 In-Ear Monitor Volume Controller allows the volume of the monitor signal sent from the mixing console to be quickly adjusted to the musician's actual needs without having to signal the sound engineer. The lightweight belt-pack unit is designed for performers who remain in a relatively fixed position on stage. It operates as a passive volume control and requires no batteries.
