DD ddHiFi TC44Grip Grip-Style Hi-Res DAC & AMP with PD

Stick, Attach, Plug – Secure to Your Phone in 3 Steps.

For optimal performance, we recommend attaching the attraction pad  to your phone case. Position it approximately 10mm from the bottom edge (placement doesn't need to be exact).

Align the bottom groove of the TC44Grip with the attraction pad and attach it securely to the back of your phone. Then, pull out the USB-C plug of the cable and insert it into your phone's charging port.

Engineered for Performance, Inside and Out

The Internal Architecture of Grip

Based on the third-generation of the ddHiFi TC44 series, the Grip utilizes dual Cirrus Logic CS43198 DAC chips to redefine audio experiences with multidimensional technical advantages. For the amplifier section, it employs dual SGM8262-2 independent op-amps. To ensure a comfortable and fatigue-free listening experience, special tuning control has been applied to the amplitude stacking of the DAC and AMP. Additionally, it is equipped with high-efficiency power and charging management chips, giving the Grip an unprecedented sound quality within the TC44 series.

The External Connection of Grip

The Grip breaks away from the traditional 'dangling dongle' design by integrating a thick shielded pure silver cable into its main body. At the back of the housing, a dedicated cable groove allows the cable to slide forward and backward during plugging or unplugging, while a wide radius curve at the base seamlessly guides the cable into the body—resulting in a unified, streamlined aesthetic.

Listening while Charging

Connecting to Earphones: 

Your phone will automatically detect and switch to headphone output mode, allowing you to connect either 3.5mm or 4.4mm earphones for immediate use. When using 3.5mm earphones with built-in microphone and remote control functions, you'll be able to control music playback and make phone calls directly through the inline controls.

Charging Your Phone:

The TC44Grip supports music playback while charging your phone. Connect a PD-compatible power supply to the USB-C charging  port for up to 60W fast charging*.

*Note: Actual charging power depends on the playback device's PD protocol compatibility and the connected power supply. Real-world testing shows:

• iPhone 16 Pro: ~25W max
• Android smartphones: 10-30W range
• Tablets/laptops: Up to 60W max

Applying the Attraction Pad and Decorative Pad

Attraction Pad

• Aluminum Alloy Attraction Pad: Contains a strong magnet with powerful attraction—ideal for prolonged and intensive daily use.
• Leather Attraction Pad: Contains only an embedded ferromagnetic plate (no additional magnets) with moderate magnetic strength—suitable for occasional use.

Decorative Pad

For enhanced comfort and grip, attach the included decorative pad to the carbon fiber surface of the TC44Grip.

The package contains two color options (black and khaki) - simply choose your preferred style and secure it in place.
