Since it had cancelled 3.5mm stereo socket from smartphones, tiny USB DAC device being popular, long times ago there some huge DAC + AMP solution provides good sound quality to audiophiles, but, not all people would like bringing such a "brick" to go outside. So "Little tail" USB key (tiny sized DAC) became a premium solution for more people.

But I just never buy one of them, I would be mind timbre of human or each instuments more than warmer/ sweeter sound, so I'll hard find a such small device as I want.
Until I receive Link2 from XDUOO.

In its small package, contains
Link2,
Type-C to Lighting cable,
Type-C to Type-C cable
and a Type-C to Type-A adaptor.
Which would fully adaptive for both iPhone and Android phones, evev fully considered the necessaries of PC adaptive.

It did use a SoC from ESS which was 9118EC, but it was told they skip the build-in AMP, but had a independent AMP, and it had 2 filters: BASS and SOUNDSTAGE enhancement.

When I try it with my phones, it was convient that I don't need any operation that only open my music apps, then I'll enjoy my music, it was greater power to drive a earphone even low impedence, wider soundstage and more detail than original adaptions I had.
And 2 sets of filters are easy using, effective but no obvious distortion to be heard, so it was a overall good selection for users.

But unlike some high output USB device, it was no any background noise, which makes me feel lile listening to a real DAP.

But there still some lackage of the product: on-body remote will be to bypass the remote and mic of a headset, more power consumption will be add to your phone that means reducing you battery life. But in other case, when you're walking or doing something, to click a key on DAC besides you pocket will be more convient than to touch your remote on you headset.

In conclusion, it was a 699 RMB product which shall be meant 120~130 USD, but it's sound quality was compectitive to 200+ USD DAP, but it needs you phone and need its battery life. It was totally good to buy for enjoy better sound quality, which is not perfect but good enough.
