With the Bluetooth headphones M300B, powerful bass is now even more enjoyable. A very long battery life, the option for alternative cable use, practical voice control, and a comfortable fit complete these Bluetooth over-ear headphones. The equalizer can be activated at the push of a button, providing an even more powerful bass. This results in optimized sound and a more defined bass reproduction. The XBS DEEP playback technology (Extra Bass System Deep) allows for well-defined, deep bass that you can feel—almost like at a live concert. The pressure on the ears is so evenly distributed with the M300 that it allows for better adaptation to the shape of the head. This ensures that Panasonic headphones provide optimal wearing comfort even during long listening sessions.
