Terrible customer service, misleading and lying.
I bought equipment that turned out to be faulty. I made a video to show Fosi support what the problem was. Based on the video, support accepted the complaint, writing that it was the relay's fault. When faced with a refund for return shipping, they offered me a partial refund for the order - I refused. I sent them the equipment. They quickly gave me a refund for the equipment but not for shipping. I am fighting with them to get my money back.
The worst thing is that I have exchanged a ton of emails with them and it is costing me stress.
Never again shopping at fosiaudio.com.
I am warning you!

Sorry but it’s true they are selling equipment which they admit IS FAULTY!!!!!!!!!!
I returned faulty items by 24/7 SPECIAL DELIVERY which means someone had to sign for delivery and they still refuse to accept they have the item!!!!!!!!
Thankfully eBay have stepped in and got me a FULL REFUND

Frustrating Audio
I've had the same issue as others, it's a good product if it arrived complete and undamaged, when there is a problem they will waste your time rather than simply resolve the issue.
If you want to chance it with them, make sure you use PayPal or a credit card so you can charge back if it gets to that, because it unfortunately might.
I hope Fosi takes note of these issues, they could be a good company if their service was improved even to just an acceptable level.

Fosi could be good.. but they aren't
I would like to start positively - that is to say, having listened to the ZD3 DAC and V3 Mono amps, I think they sound great. There are some strange anomalies through HDMI, the sound has strange echo effect for a few seconds and then goes back to normal now and then, otherwise no problem. The remote is as cheap as they get, but works.
Now to the reality of the Fosi Audio experience.. The DAC had parts missing and one of the amps has very noticeable cosmetic damage at the top front. As this was bought new, I would expect new condition, though understand mistakes happen, which is also when you learn whether a company is good or bad. Unfortunately Fosi Audio are exceptionally bad when it comes to communication and after sales, one email a day if you're lucky, and even then it makes little sense, and they will mess you around for as long as they can. I am at the point that despite enjoying the sound, I may just send it all back for a refund and try something else, they are astonishingly poor in their after sales, so if you do risk it, don't wait too long to get your money back if there is a problem.
You may get lucky, some seem to, on here it seems 50/50 what experience you shall have, these aren't good odds when it comes to a purchase like this and your consumer rights.
I hope Fosi sort it out, as they could be a decent brand if not for this, but until they fix the basics in their customer service, I would not have confidence in them and could not recommend them unfortunately.

No admiten devoluciones
En la web de Fosi Audio se indica claramente que el cliente tiene un período de 30 días para devolver el pedido, y ello sin que suponga coste alguno más allá de los gastos de envío.
Al intentar hacer uso de esta política la compañía pone todos los obstáculos imaginables. Entre ellos el más llamativo es que exigen hacer algo ilegal - a saber: demanda que, al enviarles el producto, indique un valor de 10$, cuando el valor real es de 450$. La razón es que de este modo pueden evitar los impuestos de la aduana china.
En caso de ignorar tal admonición los gastos derivados del paso por aduana correrán íntegramente por mi cuenta.
¿Qué tipo de compañía exige a sus clientes incurrir en prácticas ilegales?

DS2 2024 DAC/amp dongle
DS2 2024 DAC/amp dongle. Does not initialize properly, losing the beginning of the song/program.
Naught but empty niceties and a complete run-around from Fosi, on the pretext of soliciting my help to figure out the problem - a defect in the product of which they must surely be aware.

Small but perfect formed.
Had this little beauty for several months. It does what it says on the box. It’s a, tiny, reliable Bluetooth amp. For the price, there is nothing to touch it.
Yes, you have to switch it off, at the amp, before plugging in or disconnecting. But that should be no shock, as its said clearly, in the instructions.
Ivenot had to deal with the Chinese company. As in the U.K., it’s the vendor that’s responsible for guarantee repairs or problems.
But, as I’ve seen here. “It didn’t do what I thought/wanted. Isn’t the makers or vendors fault. It’s entirely down to the purchaser.
Pick one up, you won’t be dissatisfied.
