XBS DEEP Delivers Premium Bass Performance

Equipped with Panasonic’s bass playback technology “XBS DEEP (Extra Bass System Deep) *1”, these headphones are built for enjoying low frequency music such as dubstep, trap, rap and hip hop. The XBS DEEP playback technology was developed by optimal tuning of the housing structure with the driver equalizing function providing powerful bass performance with unprecedented, well-defined deep bass response.

Experience Concert-Quality Bass Sound

Further improving the bass performance is the built-in Bass Reactorwhich amplifies low frequencies in response to the track’s bass sounds. The Bass Reactor simulates deep, booming bass, like that in a night club or concert, by transmitting amplified low-end sound directly to the ears as real low-frequency vibrations.

*1 XBS DEEP (Extra Bass System Deep) is a fusion of three technologies: Harmonic Tuning EQ, Free-Edge Driver System, and Bass-Blow Port.

Harmonic Tuning EQ

Equipped with harmonic tuning EQ, the headphones provide a clear, crisp bass-heavy sound bass by adjusting harmonic overtones, magnifying bass sounds below 100Hz and suppressing above 100Hz.

Bass-Blow Port

The headphones’ structure further contributes to the bass performance with optimal positioning of the air outflow port in the cabinet, allowing the diaphragm’s precise piston movement to crisply reproduce low-end frequency outlines.

Free-Edge Driver System

A 40mm driver unit produces sound evenly through the distortion-resistant diaphragm and allows the headphones to achieve a deep, delicate bass.

Designed for Comfort and Long-Term Wear

The RB-M700B and RB-M500B headphones are designed for comfortable, long-term wear enabled by Side Pressure Dispersion Technology which ergonomically adjusts the lateral pressure balance between the headband and ear pads.

The RB-M700B ($179.99) and the RB-M500B ($149.99) are available in black or cream from authorized Panasonic dealers.
