Apple iPhone 11 Pro Max

Telephoning with excellent Acoustics

The Apple iPhone 11 Pro Max provides excellent sound quality and supports HD Voice (Plus) – even with Voice over LTE (VoLTE).
If your call partner also calls via 3G or VoLTE with HD Voice (Plus), you will experience a better sound quality than ISDN in the fixed network!
You can recognize callers and their state of mind in the voice and conversations remain more relaxed, because no disturbing noises annoy.
