With separate earbuds, the A801 offers unlimited freedom when listening to music and conducting phone calls. Bluetooth 5.0 guarantees a stable connection between the earbuds and a source player; in addition, ambient noise is filtered out to optimise call quality. Phone calls, music or information provided by the integrated Siri voice as­sistant is controlled or retrieved by tapping the left earbud. A single battery charge powers the earbuds for around six hours of runtime, which can be extended thanks to the charging box.
