Questions and answers

When does Fosi Audio run sales?: Fosi Audio discounts most often around Black Friday, Prime Day, and its own site promotions, and the V3 amp has been cut to half price during those windows. Prices also drift on Amazon and AliExpress between events, so check the price history before buying.
Where is Fosi Audio cheapest?: Fosi Audio's own store and Amazon usually trade the lowest price, with AliExpress sometimes undercutting both during sales. Deal.ai compares every store's price for the same model, so check the listing rather than assuming one store is always cheapest.
What are Fosi Audio's best products?: The V3 stereo amp is the standout: a small Class D amp rated at 100W per channel into 4 ohms for desktop or bookshelf setups. The BT20A Pro adds Bluetooth and tone controls, and the BT30D suits a 2.1 setup with a subwoofer output.
What is Fosi Audio's return policy?: Orders bought directly from Fosi Audio can be returned within 30 days of delivery if the item is in its original condition, and buyers cover return shipping unless the unit is defective. Amazon and other retailers apply their own return windows instead.
Do Fosi Audio amps include a power supply?: Most Fosi Audio amps ship with a matching power brick, but the wattage varies by listing and a larger supply raises the output. Check the included adapter before comparing prices, since some listings sell the amp alone.
