Our Verdict
I spent two weeks integrating the Cayin RU7 into my daily commute to see if its discrete 1-bit architecture actually makes a difference over standard dongles. This compact device promises a more natural, analog-like sound signature by utilizing a specialized resistor network rather than traditional DAC chips.

Setting up the RU7 is as simple as plugging the USB-C connector into any smartphone or laptop, with instant recognition across most major operating systems. Its lightweight, compact frame makes it an unobtrusive companion that never feels like a burden in a pocket or bag.
This is the perfect upgrade for audio enthusiasts looking to transform their smartphone into a high-fidelity listening station without carrying bulky external hardware.
