Double-sided Symmetrical Triangle

As our previous products, DDHIFI is keen to provide the most advanced product with its unique aesthetics. The TC44B looks like a triangle cheese that wrapped with matcha skin. One side is the headphone output ports, and the other side is the input cable. The look is so usual that you will never take your eyes off on it.

Dual DAC Chips

Apart from its exquisite craftsmanship, TC44B also excels in function. Featuring dual DACs, it is able to boost high impedance headphones. We have also made optimization to its output power range, so as to get better sound quality when use with smartphone.

Wide Compatibility, Both Windows or OS Works

For OS system, there’s no need to install a separate driver but for Windows system you may need to download the driver via the web. It’s compatible for both systems so no more worries about compatibility.

Durable and Reliable Cable

For the cable part, we have selected silver-plated OCC wire with TPU coating to ensure a wear-resistant, shock-resistant, and impact-resistant cable transmission. It feels soft and thin, but the strength is there. You will feel the energy of TC44B when you get to know it.

My favorite DAP/DAC for Mobile Use

This is probably my favorite DAP/DAC to use with my phone.
Streaming off of Apple lossless, everything sounds super crisp. Comparable quality with my desktop DAC/AMP setups.
The 4.4mm/2.2mm outputs give enough power to drive my most demanding tribrid IEM's as well as headphones.
On top of that, it's super compact and i dont have to go about charging the thing. Just plug and play

Steve Fultz
Works pretty good!

I bought this dac so I wouldn’t have to change cables on my balanced IEMs. Only thing is I have to twist the end that goes in the connector on the IEM to make contact on one channel. Other than that it sounds really good. Plenty of power to drive most IEMs. Recommended! I use the 4.4 connection, haven’t used the 2.5 ye.
