This past summer, Fiio introduced the QX3, a new flagship portable DAC and headphone amplifier designed for audiophiles who want to get the most out of their wired headphones while commuting or traveling. It costs over $200 and can fit in your pocket.
Fast forward to the present, and the affordable hi-fi brand is introducing something similar, only significantly smaller and less expensive. Meet the Snowsky Tiny.
Fiio Snowsky Tiny

A pocketable DAC/amp
Fiio’s Snowsky Tiny is a portable DAC and headphone amplifier that works with most USB-C devices — including smartphones, tablets, and computers — and provides an audio boost for your connected wired headphones.
The Snowsky Tiny is a fairly straightforward hi-fi gadget — it replaces your device’s built-in DAC and headphone amplifier, which are typically not very good — but it does come with a few neat tricks.
