Reviews last updated: November 2026 · How we calculate this

What customers like about Panasonic RB M300b

  • Powerful and punchy bass, further enhanced by a dedicated XBS DEEP bass-boost switch
  • Exceptional battery life, providing up to 50 hours of playback on a single charge
  • High level of comfort for long-term use due to well-padded, soft ear cups
  • Excellent value for money, frequently praised as a high-quality budget option
  • Versatile connectivity options, supporting both Bluetooth 5.0 and a 3.5mm wired connection
  • Useful quick-charge feature, offering 3 hours of playback from a 15-minute charge
  • Effective passive noise isolation despite lacking active noise cancellation

What customers don't like about Panasonic RB M300b

  • Lack of Active Noise Cancellation (ANC), which limits performance in very loud environments
  • Controls can be difficult to use, with small, non-intuitive buttons clustered closely together
  • Bulky design that does not fold, making them less portable for travel
  • Potential durability issues, specifically regarding the plastic hinges over long-term use
  • No storage case or protective pouch included in the package
  • Large size can make them feel heavy or too warm for some users during extended wear
  • Sound can become 'muddy' or lose clarity in higher frequencies when bass is at maximum

Verdict

The Panasonic RB-M300B is a wireless over-ear headphone featuring 40mm Neodymium Free Edge drivers and XBS DEEP (Extra Bass System Deep) technology designed for powerful, low-frequency performance. Main characteristics include a dedicated Bass Enhancer button for amplified low-end clarity, Bluetooth 5.0 connectivity with a 10-meter range, and an impressive battery life of up to 50 hours of continuous playback on a 4-hour charge. Its primary pros are the exceptional comfort provided by Side Pressure Dispersion Technology and soft-cushioned ear pads, as well as a quick-charge feature that offers 3 hours of listening from a 15-minute charge. 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 may not be suitable for high-intensity physical activities.
