Thanks to adaptive noise cancellation, the WI-1000X wireless in-ear headphones enable a customised music experience. In connection with a smartphone app, the user’s state of activity is registered, whether in motion or waiting quietly. Also, the extent of noise cancellation and the sound settings are adjusted automatically. The dynamic 9 mm driver and an airtight balanced armature unit provide balanced sound with rich bass, as well as a clear mid-range and sparkling treble.
