TANCHJIM ZERO Earphone In-Ear HiFi Dynamic Driver Earphone

Very good product for your money, came quickly, everything is fine

Great little DAC/AMP, no noise even on high gain mode with my most sensitive audio gear.
Build quality feels solid.

Fast delivery good

Beautiful exact sound. Solo piano, chamber formulations-sound refined, barking hearing with obertons.
Headphones-in my case, audio-Technika 900 and 990-sound no less excellent. The power is much more than enough. Low-ohm? Yes. Highly sensitive? Yes. And why yourself for your money to arrange problems with high-volume headphones.
Cool machine. Just cool.

Gorgeous DAC! Many thanks to the seller!
