Relaxed listening to music and phone calls: The ANC in-ear headphones are wireless - so you always have enough freedom of movement. For example, you can relax on the phone while going for a walk, or while taking notes and working on your PC at the same time. With the in-ear headphones, you can also always have the right music playing to motivate you when doing sport. For uninterrupted music enjoyment: thanks to active noise cancellation (ANC), distracting external noise is reliably blocked out. You can listen to music undisturbed or concentrate on a conversation partner, as your in-ear headphones also have a built-in microphone for incoming phone calls. Always ready: A multifunctional touchscreen on the charging box gives you direct access to all the important functions of the in-ear headphones without having to take out your mobile phone. A playing time of up to 4 hours is possible at medium volume. This means you are even equipped for longer trips or can listen to music while exercising in the gym. The charging process itself only takes around 90 minutes. If the headphones are not in use, standby times of up to 300 hours are possible in the charging box.
