Customer Reviews
This amp is amazing! The balanced output is superb, offering better separation and dynamics compared to other amps I’ve used. The CNC-milled aluminum shell not only looks great but feels incredibly solid. The high/low gain switch is perfect for switching between my sensitive earbuds and more demanding over-ear headphones. I highly recommend the DT03 for anyone looking to elevate their listening experience!
I’ve been blown away by the DT03 headphone amp! The 3.5mm single-ended and 4.4mm balanced outputs give me flexibility for all my headphones, and the sound quality is impeccable. The CNC-milled aluminum shell feels premium and sturdy, and the compact design makes it easy to carry. The high/low gain switch is a fantastic feature—it handles both my sensitive IEMs and high-impedance headphones with ease. Highly recommend this little gem for audiophiles on the go!
Interesting sound of the reserve in volume above the roof, detailing layering. Fast delivery.
It arrived in a few days from the order. Fast! The attached case is also good, even when the case is installed, the reaction to the button is also good. It looked calm, light weight that was easy to carry, and in addition, the sound quality was good and refreshing, and it was the correct answer to buy.
This is a great sounding dongle. Paired with the S08 they can turn a cheap phone into a mid range DAP. I've only use the balanced output so far. It has more than enough power even for planar IEMs. Smooth clear detailed sound with no discernable noise. I am very impressed. If I have to be picky an independent volume control and the ability to skip tracks like my Hiby dongle would be nice but the DT03 sounds better and that's my main priority. It even improves the sound from my Hiby R3ii.
