Thanks to the Bass Boost function, you can enjoy an extra-powerful bass. Enjoy your favorite songs on the go with the JVC HA-S65BN. Use Bluetooth to wirelessly stream music from your smartphone or tablet to the headphones. When you're in a crowded environment, ambient noises will be blocked out by the active noise canceling. You'll be able to listen to your favorite artists in peace. Do you listen to both calm and loud music? In that case, you can control whether to turn the Bass Boost function on or off. That way, you'll have more control over your music.
