Le rendu sonore est bluffant pour cette taille. La sortie 4.4mm est puissante et propre, parfait pour mes écouteurs à haute impédance.

Bought this for long flights and it doesn't disappoint. Battery life is decent, and the EQ really helps tailor the sound to my IEMs.

Toller Klang, sehr neutral und detailreich. Die Verarbeitung ist erstklassig, und die 4.4mm Buchse liefert eine beeindruckende Dynamik.

I was skeptical about the price, but it's worth every penny. The detail retrieval and soundstage are excellent for a portable DAC.

What Is MQA? The Fold-and-Unfold Trick, the Controversy, and Whether It's Worth Enabling (Tested on KEYSION 02 Pro)
For dongle-DAC users who keep running into the MQA badge on streaming platforms and aren't sure whether to switch it on. MQA isn't a new format.

What Is Soundstage and Imaging? How Headphones Create a Sense of Space
Soundstage is the width, depth and height of the sound field. Imaging is how precisely instruments and vocals are positioned. They're not the same thing — some headphones have a wide stage but blurry imaging, others have sharp imaging but a small space. Driver type, enclosure design, tuning, and even your DAC/amp all play a role. A low-distortion source like the KEYSION 02 helps imaging feel more solid.
