DD ddHiFi TC44CM2 USB-C to 4.4mm Hi-Res DAC & AMP Adapter
High-Integration 4.4 Adapter Cable
The TC44CM2 features a traditional extension cable design, commonly referred to as a "little tail" cable. This cable connects to your mobile device's USB port and then adapts to a 4.4mm balanced interface for wired earphone or audio equipment. The USB plug boasts a high level of integration, housing independent DAC and two ES9603Q headphone amplifier chips.

True all-round shielding
Molded design + full metal shielding is a high-cost manufacturing process used for audiophile-grade products. The TC44CM2 has a sturdy, braided shielding structure, and the USB-C plug and 4.4mm socket are both molded, with a CNC-machined aviation aluminum housing to achieve true all-round shielding.

Independent DAC and Dual-Channel OP-AMP
The TC44CM2 features an independent DAC chip and dual-channel OP-AMP architecture, adhering to a true balanced design. It supports decoding up to 32-bit/384kHz, with an output power of up to 330mW, making it suitable for most earbuds and some over-ear headphones.
Note: If you experience noise while using certain phone models with specific music apps, it may be due to the USB exclusive mode being enabled. Disabling this feature should resolve the issue.
Excellent compatibility
It is compatible with most USB-C audio output devices, including Android smartphones, iPhone 15, tablets, and laptops.

Durable and Robust
The TC44CM2 is well-suited for challenging work environments where earphone cables may be frequently pulled or compressed. Thanks to its excellent craftsmanship and high-quality materials, the TC44CM2 ensures stable music output even under demanding conditions.
