In spite of its compact body, the 9mm Driver Unit delivers
crisp, clear sound and robust bass. The high sound
insulation of this canal-type model lets you immerse
yourself in the music.
The ergonomic design makes these headphones easy
to wear, fitting firmly into the ears to resist falling out.
Even with their wireless design, the lightweight,
compact body provides a comfortable fit.
