As Seen On

“This is what happens when a company is laser focused on customer needs and excellence in engineering.”

"If you want a small, simple, affordable integrated amp with lots of power, the Fosi Audio BT20A Pro is your best choice."

“Are they the last word in anything? Of course not. But where value for money is concerned – and that is made up of a combination of performance, specification, build quality, pride of ownership, user interface (such as it is where a product like the V3 monoblock is concerned) – the company seems to hit the nail on the head.”

“Team Fosi does clear, controlled, clean-as-a-whistle ‘hi-fi’ like a dream”

"Long story short, the Fosi V3 Mono Amp is one of the best power amplifiers I have ever reviewed to this day."

"It may not look like it, but the Fosi Audio BT20A Pro is a powerful amplifier in a small package. It may be barebones, but it sounds bigger than the price tag would have you expecting."

"You don’t need to spend thousands or even hundreds to gain entry into Audiophile Land. Fosi Audio’s DS2 2024 is proof of that!"

"What I have learned for sure, though, is that Fosi Audio goes about things the right way and is far more sincere than it is cynical in its efforts to part you from your hard-earned."

"The affordable Fosi Audio DS1 is our favorite headphone amp/DAC because it has the needed connections and power output to suit most headphones."
