Reviews last updated: November 2026 · How we calculate this

What customers like about Panasonic RB M500B

  • Powerful, 'skull-rattling' bass performance through the Bass Reactor vibration system
  • Exceptional battery life, typically offering up to 30 hours of wireless playback
  • High comfort levels with soft, plush ear cushions suitable for long listening sessions
  • Quick-charge feature provides 2 hours of playback from just a 15-minute charge
  • Solid connectivity with stable Bluetooth 5.0 and an included 3.5mm cable for wired use

What customers don't like about Panasonic RB M500B

  • Lack of Active Noise Cancelling (ANC), relying only on passive isolation
  • Bulky, non-collapsible design makes them less ideal for frequent travel
  • Onboard controls and buttons can be small, flat, and difficult to distinguish by touch
  • Poor companion app performance, with some users reporting it fails to detect the device
  • Built-in microphone quality is sometimes described as quiet or muffled during calls

Verdict

The Panasonic RB-M500B is an over-ear wireless headphone featuring 40mm Neodymium dynamic drivers and specialized XBS DEEP technology for enhanced low-frequency performance. Its standout feature is a 3-level adjustable 'Bass Reactor' that creates physical vibrations to simulate a live concert experience. Connectivity includes Bluetooth 5.0 with AAC and SBC codec support, as well as a 1.2m detachable 3.5mm cable for wired use. Key specifications include a frequency response of 20Hz–20kHz, 27Ω impedance, and a 30-hour battery life that supports quick charging via USB-C (15 minutes for 2 hours of playback). Major pros include a highly comfortable fit due to Side Pressure Dispersion Technology and exceptionally powerful, tactile bass that appeals to bass enthusiasts. However, notable cons include the lack of active noise cancellation (ANC), the absence of a carrying case in the box, and a bulky design that is not ideal for travel.
