Key Features

    High-Resolution Audio Decoding:
    Equipped with the high-performance Conexant CX31993 DAC chip, the D2 decodes PCM audio signals up to 32-bit/384kHz, delivering clear highs, natural vocals, and controlled bass response.

    Full Microphone and In-Line Control Support:
    Unlike standard audio dongles, the D2 features built-in ADC microphone support, enabling seamless voice calls, gaming chat, and in-line remote control functionality without sacrificing sound quality.

    Durable Aluminum Alloy Construction:
    Crafted with CNC-machined aluminum end housings and a flexible high-purity oxygen-free copper cable, the D2 offers efficient heat dissipation, electromagnetic shielding, and daily wear resistance.

    Drivers-Free Plug and Play:
    Connect instantly to your devices without installing extra software or drivers. The bus-powered design draws minimal power directly from your host device, eliminating the need for internal batteries or external charging.

    Low Noise Floor and Wide Compatibility:
    Boasting a 100 dB signal-to-noise ratio, the D2 eliminates background hiss and static, making it ideal for sensitive in-ear monitors as well as standard headphones up to 300 Ohms.
