Wireless in-ear headphones, called true wireless, have to be able to do several things in the smallest of spaces: produce good sound, eliminate outside noise and sit comfortably. With the Quietcomfort Earbuds II, Bose tries to convince in all disciplines – and also succeeds, as a short listening and wearing test showed. The Americans use their new Customtune technology for this purpose. As soon as the plugs are in the ear, the QC Earbuds II measure the frequency response in order to adjust the sound and noise canceling through calibration. Because every auditory canal is different and influences the behavior of the sound waves. Few other manufacturers use similar methods. The Quietcomfort Earbuds II cost 300 euros. (made.)
