Hi Y'all

Hi Y'all. I bought a Fosi ZD3 today. Its connected to a vintage Quad 33/303 amplifier set up. What to say? It's been running all afternoon. Amazing sound. Now I use the Marantz CD6000 purely as a transport. The TV via Toslink sounds so much better. All in all, it is a bargain.

Awful customer service
.beware

Update: it appears that posting a review here got noticed. Fosil have now returned the money and said I can keep the Amp. The amp is in the bin however as it was unusabl. This should have been dealt with with my original customer complaint as either unfit for purpose or faulty.

So, I’d still recommend not buying this due to customer service and returns issues. If you do use Amazon uk not direct to Fosil.

“
.. I recently ordered a BT30 amp and it suffered from terrible hum on the active sub output. I tried to return the amp and I’ve been given a total run around by the returns team who have asked me to change literally everything except the amp itself. I’ve never had any issues in the past with my setup with any other amp

Just received PH05 5 way headphone


Just received PH05 5 way headphone amplifier. Can’t comment on reliability, but quality, both of construction and sound, are great at any price, but really remarkable at £50. Music actually sounds more immersive through this than direct from source - I don’t know how that’s possible. I haven’t read other reviews, and can’t comment on other products, but this one is great so far.

Excellent products and service

I've bought a bluetooth amp and a bluetooth volume control. Both excellent products and a pleasure to use.

Recently ordered some other stuff from them. I messed up my order and accidently ended up ordering double of some items. I raised the issue from their website and they very quickly fixed the order

Used to be good just don't care about customers' anymore!

I started to contact them at 6.39am due to time difference and I didn’t finish or I disconnected after 8.30am. They promised me a new part that had production problems and this was about 1 years ago.
They wanted proof that they promised to send me the improved part to replace a defective one!
Well they just ignored me because I had no proof just a conversation about the time production was going to take place a year ago. By this time I changed my phone and the women who worked there left. The worst thing its they left me hanging for an hour with no response no recognition that they weren’t going to help. Thats fine, but to ignore your customer base is just wrong, especially giving evidence to the problem.
I was a fan of their products, but be warned I will never buy another Fosi Audio product after this customer service experience.
Sad to see it decline but I really don’t want anyone to experience what I just went through!!

Customer service lies, changes minds, misleads

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!

FOSI ARE CROOKS!!!!!!!!
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.

Hifi Fosi Audio

Hi, I purchased the P3 preamp and ZA3 power amp, but when I plugged everything in there was no sound coming out of the speakers. I contacted Fosi via their chat and they immediately took an interest in my problem. Following their verification advice, before returning the product, I identified the cause. Now the system sounds great. The music is rich in nuances and without any distortion. Excellent Hifi at a reasonable price. Highly recommended manufacturer/seller.

Do not trust.

Their product didn't work as intended, to recieve a refund I had to open a case with Paypal as Fosiaudio kept on stringing me along, day after day for nearly two weeks witholding their return address. At the end their conduct wasn't inspiring any trust in them at all and I would never shop there again.

Do not buy with confidence.

Fosiaudio sold me a headphone amplifier


Fosiaudio sold me a headphone amplifier that did not do what they said it would do and will not refund my money. After I received the amplifier and told them it would not do the job they said it would do they told me I needed an ADDITIONAL product that they sold in order for the amplifier to work.
So far, they just tell me one story after another.

Fosi Audio BT20A With 24V Power Supply

So glad I bought this amp!
Hooked it up via Bluetooth to a pair B & W 601 speakers (circa 1998!) which had been languishing unused for the last seven years! The sound quality via the Fosi amp is great! I also have Sonos One paired up, and they do not compare to the sound I am getting out of the amp and old speakers. I purchased directly from their website and not via Amazon. This was much cheaper and customer service was excellent, with any queries answered promptly. The order was delivered to me within 9 days!
If you have a good pair of passive speakers and want to use them again, go for Fosi!
