After spending almost a week listening to this unit, without a doubt it is exactly identical sounding to ZOOAUX 2nd GEN and KINSOUND Dongles. And they should sound the same because internally they are identical to each other. Not a surprise at all since it is a lot easier for different brands now to obtain OEM CX DACs and package them differently. What must be acknowledged, just like ZOOAUX Gen 2 and KINSOUND, AuxLink HIFI Pro offers great sound in a very affordable package. That alone makes it a worthy purchase for casual usage and listening.

⭐⭐⭐⭐ ($8.00)

Best Pairing: Flexible for anything less demanding under 100Ω
