    The business seems good amplifier. Computer and amplifier and carry the music, game such as sound for Saw seems sound quality is good. Bluetooth connection saw should be used for low-end amplifier bluetooth sound quality is not good, and used this product is check whether it seems. Of course, wired cable when connected with the sound quality is more good, it seems that the production each children but bluetooth sound quality-haven’t heard enough to me worse it, but does the rest.
    Product packaging box attitude was high, shipping believe grew quicker. goods buyers in September 14th expected is called had the expected than goods received. September days in order to September days to received.

    The postal package was opened. The store service 5 took on the camera. The box is not sealed and crumpled. I can see the autopsy marks. But the amplifier without visible violations. I have to check. For a very long time the 5post service carried the parcel from Moscow to Tambov through Voronezh, Ryazan, and again to Voronezh.

    AIYIMA A03 model is garbage.
    The chip is not 3116. Because of that, the sound is tangled up, which is annoying to hear.
    So I bought the FOSI BT20A model. This product sounds ‘honest’. It is clean. I am very satisfied.
    Thanks FOSI Audio~

    Good afternoon. Connected to passive speakers that are 65Watt. I do not think that this amplifier on one channel only gives out 100 watt, rather 50 watt per channel, but I can make a mistake. The sound quality when connected via Bluetooth did not please, the more the sound, the worse the sound. I use the connection through the cable. There is a tangible difference than when connected via Bluetooth. The sound became cleaner. For me, there are not enough average frequencies. In general, the amplifier, although small in size, but bright. A good amplifier for your money. Happy with the purchase. The store is reliable. The seller is sociable. The seller sent me a cable with an American plug by mistake, although I asked to send a network cable with a European plug, but after sorry and sent another network cable with a European Plug Plug plug Buy, you will not regret. The amplifier is worth its money. Good luck to all!!!

    He arrived in 2 days from Madrid. Super fast. Very good sound quality for what you pay. I already have 4 Fosi amplifiers and this is the cleanest sound. It’s the second one he bought. I ‘d miss it if I had a little more serious, but I’m happy. If you want more power with more bass and less sharp the Fosi Bl 20 C goes great but buy the one with Bluetooth antenna.

    Prompt delivery, connected to the central channel JBL studio pulls about half, the middle is not enough. There are no wheezes, Chinese voices, the detection immediately finds me, but it does not connect automatically immediately.
