Great produkt, great service
Stand Its stále and good working.Fas shopping.
I purchased the Merak CD player with the IM4 in ear monitors and it's been a blast using both. The Merak CD player sounds much better than I anticipated and I've rekindled my love for my CD collection. The IM4's punch above their weight and are among the best sounding in ears I've ever tried. Both shipped quickly and were well packaged. I can't say enough good things about my experience dipping into the world of Fosi Audio products.

Mycket bra varor
I got a Power Supply from Fosi Audio. The product is of high quality and delivery was very fast. Highly Recommended !
Incredible performance out of such a small device! Love it!
👌
Units arrived in working condition. Just plugged them in to see if all looked good. It dis. Have not had the time to hook them up and listen as yet. probably in a couple of months.
Was unaware I needed a 2.1 amp & not a 2.0 amp like the one I got. Want to do an exchange or return for credit on next purchase so that I can get the gear I actually need for my setup

Unfortunately one of my V3 amp blew after only a few uses. I decided to return the entire purchase and go a different route for now. The return process was easy and relatively fast.

I really wanted to try this but I'm still waiting on my order all I have got is it was delivered. Which is incorrect as it is not in my possession. So much for a worry free delivery

The quality of this sound was so profound that, upon listening to it, I found myself to be attracted to men.
