Panasonic releases its latest M-series wireless headphones

Panasonic has clearly pitched its new RB-M500B and RB-M700B wireless headphones at those who tend to consume bass-heavy tracks. They are packed with XBS (Extra Bass System) DEEP features such as an air outflow port that is specifically positioned so as to allow the 40mm drivers' diaphragms' "precise piston movement" to reproduce low ends as clearly as possible.

The same diaphragms have been engineered so that the drivers can pass sound through them evenly, which may produce more nuance in their bass. Panasonic calls this arrangement the "Free-Edge Driver System". The new M-series headphones also incorporate a Harmonic Tuning EQ, which emphasizes bass sounds below 100 hertz (Hz) while seeking to squash those above 100Hz.

The new Bluetooth audio devices also come equipped with "high-comfort" ear-pads that feature Side Pressure Dispersion Technology for reduced wearer fatigue over time. The RB-M500B headphones are now available for US$149.99, whereas the RB-M700Bs are $179.99 from official Panasonic dealers.

For the extra cost of the top-end variant, the buyer gets ANC and up to 20 hours of playback per charge; on the other hand, the M500Bs offer up to 10 more hours of battery life instead.
