I use a CD player in my office with a pair of headphones. Wanted a small DAC/headphone amp to improve the sound and give me more volume out of the CD player. This unit perfectly serves my needs and for a good price.

The Q4 was a fantastic surprise. Not only does it offer all the basic needs and connections of a dac, but it also offers control knobs for bass, treble and volume. This feature made me buy it without hesitation, even though I had never purchased anything from Fosi Audio before. Something wonderful for me that I’m a fan of vintage audio systems that offered that kind of controls. 100% recommended!!

Very pleased with sound quality I am using the Q4 DAC as a pre amp with a Bt20 pro as the power amp, connected to a set of JBL control 1 Pros and a Cambridge audio Sirrroco Sub woofer, they all work great together even Deepseek agreed it was a great match, I mostly play music via the Optical link to my Samsung 50 inch TV. HIGHLY recommend it Fosi products they have brought my music listening to life again. I created this setup as an alternative to a streaming amp which are usually to expensive. I am looking forward to hearing about the Fosi S3, but will probably be out of my price range, as apart from the Q4 all the other components where purchased preowned.
Thanks again to the Fosi team.

I used this DAC for my laptops USB output then in a pre amp and then the ZA3. An analog path is such a better and more dynamic sound then the very limited BT transfer. I also enjoy how Fosi has made the input selectors on most products a physical switch. Much more reliable and no mistaking what input I'm on.

I can't evaluate it because I haven't received it at my home yet.

The clarity and the connection is perfection. This is such a dynamic little gadget. I use it every day with my headphones to go to another land of Bliss.
