Click To Read Reviews

Build Aspect

The RB-M500B are a pair of wireless headphones designed for bass-heads Panasonic. Clearly the RB-M500B look identical to the RB-M700B. Subsequently the overall build is similar i.e., they re made from plastic with metal internals, with same durable feel. Moreover the finish is smooth with a minimal yet elegant design. One big difference here is the mechanism of ear-cups, unfortunately these smaller siblings lack swivel in the ear cups. Therefore the fitting is not as comfortable, despite the same levels of padding and cushioning. However the battery life is good as its rated for 30 hour rated runtime.

Performance Aspect

These wireless headphones are fitted with 40mm drivers. As a result they have powerful bass with lots of rumble and punch. In addition to quantity the quality of lows are also good, with bass being fast and deep. The midrange is shallow and makes vocals sound thin and unrevealing. Thankfully the treble is cohesive and dynamic. Moreover the texture is smooth therefore cymbals and hi hats sound perfect. Furthermore the microphone is decent and as a result call quality is acceptable. Are these headphones good? Yes, as far as wireless headphones under 5000 go these Panasonics are a good buy.

PROS

Well built, durable construction.
Good audio performance.
Lasting battery life.

CONS

Mid range is laid back.
Fitting is not ideal.
Flimsy buttons.
