Customer Reviews
Loving my new DAC!
The DS1 Portable DAC is absolutely fantastic! It totally changed my listening experience. The sound is so clear and punchy. I just love it! Shipping was fast too, got it in like 4 days. I'm already planning my next purchase, maybe a new preamp. You guys are awesome, I'm telling all my friends about Fosi Audio!
Great little phono preamp
I recently ordered the Box X2 Phono Preamp to upgrade my vinyl setup. The ordering process on their website was smooth enough, and I got a confirmation email right away. It shipped out in two days and arrived at my doorstep in Texas about five days later. Packaging was good, everything was secure. Installation was a breeze; literally just plugged it in and connected my turntable. The sound quality is a noticeable improvement over my receiver's built-in phono stage, much clearer and more detailed. For the price, it's a solid performer. I didn't need to contact customer support, so I can't speak to that experience, but the product itself and the delivery went well.
Good deal on a V3
This was my first time ordering from Fosi Audio. I was looking for a decent class D amp that wouldn't break the bank. I got the Fosi Audio V3 during a small sale, which helped a lot with the overall cost. Felt like I got a really good value for the sound quality it delivers. Definitely worth what I paid.
Decent amplifier, slow support
I bought the BT20A Pro a few weeks ago. The amplifier itself is quite solid for the price, performs well with my bookshelf speakers. Setup was straightforward, and the Bluetooth connection is stable. My order took about 8 days to reach me in California, which felt a little slow compared to other online stores. I had a quick question about power supply compatibility, and it took their support team a couple of days to get back to me. Not a huge issue, but an area they could improve. Overall, I'm happy with the product, just wish delivery and initial support were a bit quicker.
Fosi Audio Community Discussion
Share tips, ask questions & help fellow shoppers save more
I'm a student and looking at the BT20A Pro. Do they have a student discount or anything for new customers?
Does anyone know if Fosi Audio products are actually genuine or are there a lot of fakes out there? Saw some stuff on other sites.
Can you actually return stuff to Fosi if it's not what you expected? What's their policy like?
How does the ZA3 compare to something like a Schiit Vidar? Is Fosi Audio even in the same league?
Is the mini amplifier discount still active? Tried a code I saw but it didn't work.
