The Ultimate Personal Monitoring System for AIRA Musicians Designed and built by V-MODA in collaboration with Roland, the Crossfade M-100 AIRA is an audiophile-quality headphone for users of Roland’s AIRA range of electronic instruments and effects. With its dual-diaphragm 50 mm driver, 5–30,000 Hz frequency response and incredible dynamic range, it lets you hear and feel every detail of your performances on stage or in the studio, from the deepest subs of the TR-8 drum machine to the most piercing screams of the TB-3 bass synth.
