The Surface Headphones 2 is the new generation of headphones designed to revolutionize your listening experience. With a focus on comfort, audio quality and autonomy, these headphones allow you to live your favorite music and programs as never before. Thanks to Omnisonic audio technology, the sound is rich and enveloping, while the 13 levels of active noise cancelling allow you to isolate yourself completely and concentrate to the maximum, adjusting the noise level with a simple gesture on the wheel on the left earpiece. Touch, touch and wheel controls offer intuitive and immediate interaction to skip tracks, respond to calls and adjust the volume. In addition, the music pauses automatically when you remove your headphones and resumes when you wear them. With advanced microphones, the clarity of calls is exceptional, and the long autonomy ensures you up to 18.5 hours of music listening or up to 15 hours of voice calls on Microsoft Teams with a single charge.
