ddHiFi / TC44GRIP

The "TC44Grip" is a new type of DAC/amp proposed by ddHiFi that attaches to the back of a smartphone. It’s a smart realization of that "I wish something like this existed" concept, keeping cables neatly organized.

■ Attach, Mount, Plug In – A 3-Step Process to Secure to Your Smartphone
・Optimal Usage
For the best performance, we recommend attaching the "Attraction Pad" to your smartphone case. Position it approximately 10mm from the bottom edge (precise alignment is not required). Align the groove on the bottom of the TC44Grip with the Attraction Pad and press it firmly onto the back of your smartphone. Finally, pull out the integrated USB-C plug and connect it to your smartphone’s charging port.

■ Designed for High Performance
・Internal Architecture
Based on the 3rd generation of the ddHiFi TC44 series, the TC44Grip features dual CS43198 DAC chips, delivering an elevated audio experience through comprehensive technical advancements. The amplification stage utilizes dual independent SGM8262-2 operational amplifiers. The output balance between the DAC and the amplifier has been meticulously tuned to provide a comfortable, fatigue-free listening experience, even during extended sessions. Furthermore, the inclusion of a high-efficiency power and charging management chip enables the best sound quality in the history of the TC44 series.
・External Connectivity Design
Moving away from the traditional "dangling dongle" design, the TC44Grip integrates a thick, shielded, pure-silver cable directly into the main unit. A dedicated groove on the back of the chassis allows the cable to slide smoothly back and forth when plugging or unplugging the connector. Additionally, the base of the cable features a large-radius curve, allowing it to nestle naturally against the unit for a seamless, fluid, and unified design.

■ Enjoy Music While Charging
・Connecting Earphones
Your smartphone will automatically detect the device and switch to headphone output mode. Simply connect your earphones—via either the 3.5mm or 4.4mm jack—and you are ready to listen. When using earphones with a 3.5mm jack that feature an integrated microphone and remote control, you can use the remote to manage music playback and handle phone calls.
・Smartphone Charging
The TC44Grip supports smartphone charging, even while music is playing. By connecting a Power Delivery (PD) compatible power source to the USB-C charging port, you can achieve fast charging at up to 60W.
*Note: Some smartphone models may not be compatible.

■ Choice of Attachment Pads
・Aluminum Alloy Attachment Pad
Features a built-in, high-strength magnet. Ideal for intensive, long-term daily use.
・Leather Attachment Pad
Contains no built-in magnet; instead, it features an embedded ferromagnetic plate. Provides a moderate level of magnetic attraction, making it suitable for occasional use.
