In a market flooded with audio dongles, ddHiFi has carved out a distinct niche with its innovative lineup. Today, we delve into their latest creation, the TC44Pro E2, priced at around $99, to see if it lives up to expectations. While I'm reviewing the lightning connector version, it's worth mentioning that ddHiFi also offers a USB-C variant for users with compatible devices. Read on to find out what I think about this device.

What you get
Opening up the TC44Pro E2 package is like finding a little treasure inside. In the plain white box, you'll see the dongle snugly held by a leather strap, with an extra one and a quick start guide alongside. The leather straps are supposed to help with cable management, but honestly, I found them more decorative than useful. There's also a QR code sticker for a tutorial on tying a snake knot. Overall, the leather adds a nice touch, but I didn't find it very practical.

Built and Design
When I first held the TC44Pro E2, I was struck by its sturdy construction. The aluminum chassis gives it a reassuring weight, conveying a sense of durability and quality. What caught my eye was the attention to detail, like the reinforced metal ring atop the socket, which adds a touch of elegance and provides extra protection. Despite its robust build, it maintains a compact form factor that fits comfortably in the palm of my hand. And the addition of the cowhide rope not only adds a hint of sophistication but also serves as a practical touch. Overall, the TC44Pro E2 is not just a functional device; it's a beautifully crafted piece of technology that enhances both my auditory and visual experiences.

Functionality
The TC44Pro E2 offers seamless usability - simply plug it into your phone and connect your headphones for instant audio enhancement. With two CS43131 decoding chips and two ES9603Q independent operational amplifiers, it delivers superior sound quality and power. Its Pentaconn 4.4 mm plug and advanced circuit board ensure reliability and durability, while the reinforced metal ring provides both aesthetic appeal and protection.

Soundstage
Listening to music through the TC44Pro E2 is a revelation. Despite its balanced output, it's not designed for driving notoriously hard-to-drive headphones, but it excels with sensitive IEMs and low-impedance headphones, delivering a powerful yet controlled sound experience.
In my test with the Campfire Audio Andromeda IEMs, the TC44Pro E2 showcased impressive dynamics. From the punchy bass drums in Metallica's "Enter Sandman" to the crisp snare taps and lively cymbal crashes, every detail was rendered with precision and energy.
What sets the TC44Pro E2 apart is its transparency. The low end is rich and detailed, providing a solid foundation for impactful bass. The midrange is articulate and clear, enhancing the vocals without overshadowing the bright midrange of the Moondrop. Meanwhile, the high end remains crisp and clear, allowing every detail to shine through without harshness. Overall, the TC44Pro E2 is a remarkably transparent DAC/AMP that elevates your listening experience to new heights.



Summary
The TC44Pro E2 from ddHiFi is a standout performer in the audio dongle market, boasting an array of impressive features. Its balanced output ensures exceptional sound quality with sensitive IEMs and low-impedance headphones, delivering dynamic and transparent audio reproduction. The thoughtful design, including the reinforced metal ring and meticulous craftsmanship, enhances its appeal, making it a top choice for audiophiles seeking premium audio experiences on the move.
