DD Hifi, with its DDTC44CM2, unveils a USB-C to 4.4mm female jack DAC adapter featuring an independent DAC and two ES9603Q headphone amplification chips. Thanks to this, the TC44CM2 supports high-resolution sampling rates up to PCM 32-bit 384kHz while delivering up to 330mW under 32 ohms to drive headphones or in-ear monitors. The cable between the two connectors features pure OFC copper conductors and shielding for effective protection against interference.
If noise is audible when using this adapter with a specific phone or application, it means that the "USB only" mode is enabled on your device/application. Simply disable this feature for optimal listening.
