BOSS WAZA-AIR BASS Wireless Personal Bass Amplification System

The BOSS WAZA-AIR BASS is a wireless over-ear headphone amplifier system designed specifically for bass guitarists who want an immersive, cable-free practice experience. Using an integrated gyro sensor and advanced 3D spatial algorithms, it recreates the feel of playing through a real amplifier in a physical room — restoring the depth, resonance, and moving-air sensation that standard headphones eliminate. Simply plug the included WL-T transmitter into your bass and play.

For players seeking the best wireless headphone amp for bass guitar, the WAZA-AIR BASS stands apart from traditional silent practice solutions. Five onboard bass amp types span clean and punchy modern voicings to driven vintage tube-style tones, while over 30 bass-tuned effects — including compressor, overdrive, T-wah, octave, and bass synth — allow full creative expression without disturbing neighbors. Six onboard memory slots store favorite setups for instant recall, making this the ideal bass headphone amplifier for apartment players, home studio bassists, and touring musicians who need a consistent practice rig anywhere.

Built on the same wireless platform as BOSS's acclaimed WL series, the WAZA-AIR BASS delivers ultra-low latency performance that keeps playing feel natural and responsive. Bluetooth audio streaming lets you jam along to music from a smartphone, while 10 onboard acoustic drum patterns and an advanced metronome with 32 rhythm variations — including triplets and odd meters — turn every practice session into a productive groove workout. The BOSS Tone Studio app for iOS and Android enables wireless patch editing, drum pattern control, and access to the BOSS Tone Exchange community library.
