• With the TELEFUNKEN Audio App (iOS & Android) (coming soon), you shape your sound: boost bass, highlight voices, or choose a neutral Hi-Fi tuning – the flexible EQ ensures music, podcasts, or presentations sound exactly how you need them.
• When it comes to connectivity, the DELTA PRO is consistently practical:
  • Bluetooth 5.3 for a stable, energy-efficient connection with smartphones, tablets, or laptops.
