a short wait they are ready to be used for an extended period. When fully charged, they provide up to 6 hours of playback.

Never Fall Off

3D-Flex sport clips, Quick-fit adjuster and Canal design

The hook portion that wraps around the ear can be freely bent, providing a comfortable and optimal fit.
Once you have set them to the shape of your ears, the 3D-Flex clips remember that shape and fit snugly on your ears, even during exercise.
The BTS55 headphones have a perfect ear-fitting structure, so you can enjoy sports with your favorite music, no matter how intensely you move.

Smart Control With Your Voice

Voice Assistant Activation

You can launch smartphone voice functions such as Siri* via the remote control button. This enables you to select music,
adjust the volume, and make phone calls, without having to get your smartphone out, meaning you can stay motivated and focus on your exercise.

Robust Bass

Focus on your training with dynamic sound

BTS55 headphones feature 9mm drivers with robust bass that let you enjoy the power of the sharp beat.
They are compatible with AAC codec which allows you to listen to music wirelessly in higher quality than offered from the standard Bluetooth codec.
The flat cable routed behind the ear, significantly reduces touch noise, enabling sharp, clear sounds to be produced.
With a sound that sharpens your mood, BTS55 headphones will carry you through your workout.
