Pure Digital Drive™
Wireless digital audio signals are transmitted via Bluetooth® technology direct to the headphone driver. Unlike conventional wireless headphones, the signal remains fully in the digital domain from source without the need for Digital-to-Analog conversion and typical sound degradation.
True Motion D/A Drivers
Developed exclusively for the DSR9BT, 45mm True Motion D/A drivers combine a high-purity, 7N-OFC four-core voice coil that transmits the original digital signal for audio accuracy with a Diamond-Like Carbon (DLC) coated diaphragm for increased rigidity and enhanced frequency response.
Reproduces High-Resolution digital sources up to 24-bit/96kHz via wired USB connection and up to 24-bit/48kHz wirelessly.
