Review: Best value headphone amp ever - Almost perfect a real giant killer of a head phone amplifier. But it's also really easy to mod and that's the real gem because it's so cheap to do so. First the russian old stock tubes. But driving my HD800S this little amp falls apart when the music gets busy. Test track hans Zimmer pirates of the Caribbean. Why because it needs more power lots more. As 5v 2A only gives 10W. But I now have 5V and upto 40W available. Now it has plenty of head room hughe soundstage. Next op amp upgrade. I love this it sounds better than something 10 times the cost highly recommend.
Review: A little gem - This little headphone amp is tremendous value for money. Not only does it sound really good it has no trouble driving the most difficult headphones with it's 1100 mW output. Quality can be improved by op amp rolling if you like to experiment. I replaced the ones in mine with the Burson Audio V5i which made a big difference in the sound quality while still keeping the total cost around £100.

## Features

- Warm tips: 1. Not inlcude power adapter, recommend to use original high-quality power adapter (DC5V/≥2A ). U10 won't work normally if the current below 2A. 2. Inputs (3.5mm / RCA) and outputs (6.35mm/3.5mm jack) are connected in parallel, in other words, all inputs and outputs work simultaneously. Don't connect 3.5mm and RCA inputs at the same time, or else audio signals will be mixed.

### ⭐⭐⭐⭐⭐ important!! adapters!
*by G***. on 25 April 2025*

Good info for buyers new to headphone amps. There are two headphone jacks on the Douk U10. 3.5mm and 6.35mm. Yes you can buy adapters but even if they look bling, most of those adapters are bad quality (badly wired internally or a poor fit in the socket) and will cause a lot of noise on this amp (and other amps). You are best connecting with whatever the headphone comes with. If the headphone comes with a 3.5mm or 6.35mm connector then use that. If you really must connect with a 3.5 to 6.35 adapter buy a good one and not an unknown one. UGREEN do a decent cheaper one.
