DD ddHiFi M130B (Coffee Cable) USB-C Earphone Upgrade Cable with Microphone (Open Box)

M130B (Coffee Cable) Professional All-in-one USB-C Decoding Upgrade Cable 

Simply plug in to enjoy lossless music

The Coffee Cable is the second generation of ddHiFi's full-featured upgrade cable. It is designed to bring convenience to audiophiles who prefer to enjoy lossless music on the phone. Unlike traditional USB earphone cables, the M130B is equipped with powerful decoding and driving capabilities by using ddHiFi's new decoding and amplifier architecture inside its compact plug.

Stand-alone chips for decoding and operational amplifier

The M130B supports commonly used lossless music apps, such as Apple Music, QQ Music, Netease Cloud Music, Sony Lossless Music, etc. Most of the lossless music formats offered by music apps are 44.1kHz, 96kHz or 192kHz, while the M130B supports PCM decoding up to 384kHz. Being equipped with stand-alone decoding chip and OP-AMP chip, the M130B provides stable performance and output power, and can basically satisfy the daily needs of playing lossless music on mobile phones.

Special design for in-line controls and microphone 

Different from traditional cable, the M130B places the circuit board at the splitter position. And to ensure high fidelity transmission of sound quality, the M130B uses shielded OCC wires to connect from the in-line controller to the decoding plug, without separating the cable nor sharing the loop ground wires of the signal line, so as to provide good shielding and anti-interference effect.

Hidden inside the in-line controller is a high-performance MEMS microphone circuit that can be used for daily calls, playing games, live streaming and more. The round button in the middle can control phone calls and music playback.

Audiophile-grade OCC wire with shielding layer

The cable base of the M130B was derived from the shielded OCC earphone upgrade cable Nyx, with its main core made of high purity OCC. The cable and the decoding plug combined together for a better sound tuning.

Available in MMCX and 2-Pin 0.78 connectors
It provides MMCX and 2-Pin 0.78 connectors for option. For the MMCX connector, it not only supports earphones with regular MMCX connector, but also the new IE series earphones from Sennheiser, such as the IE900.
