The bass can not only be heard but also felt directly thanks to vibrations. A long battery life and practical voice control complete the impressive overall package of the Bluetooth over-ear headphones. Want to not just hear the bass but also feel it? No problem with the M500B. With the built-in bass reactor, the headphones are set to vibrate for an even more powerful bass experience, with adjustable intensity. The pressure on the ear is so evenly distributed in the M500B that it allows for better adaptation to the shape of the head. This ensures that Panasonic headphones provide optimal comfort even during long listening sessions.
