Fiio Q7 Portable DAC & Headphone Amplifier

Finally having both battery and DC power options means I can use it on my desk or take it out without sacrificing performance. The dual power design gives me that desktop-class sound even when I'm truly on the go.

It's basically a desktop amp that you can throw in a backpack, and the internal battery keeps the party going for hours away from a wall socket. I've been using it with my over-ear cans and the headroom is absurd—clean, effortless power even at high gain.

The dual power design is a game-changer—I can use the built-in battery on the go, then plug it in at my desk and it feels like a completely different, more powerful unit. Sound stays clean and detailed even at high volumes, which surprised me for something this size.
