Compact, Powerful & Crystal Clear!
The Fosi Audio HT4S is a fantastic little amplifier with rich, detailed sound and strong Bluetooth connectivity. It delivers clean highs, solid bass, and more power than you’d expect for its size. The build quality is premium, setup is easy, and it runs cool even after hours of use — provided you pair it with good speakers.

2 months usage review
Believe that an amplifier can turn old Sony home theatre speakers alive. The original Sony system stopped working due to motherboard issue and it being some 15-16 yrs old could not be repaired. After several research and review finally bought this amplifier. Gambling 10k on this and went ahead. Have been using daily for 12-15hrs (TV usage) and there has been no issue. Listening to music has been pretty good. One issue I faced was buzzing sound after around 15 days when connected via bluetooth and Airtel set top box however with mobile that sound was not coming. So it might be the issue with the set top box itself. Currently TV and amplifier are connected with 3mm cable and has no lag in picture and speaker.

Fosi audio HT4S amplifier
This is a very good amplifier machine, it is very strong, the sound is really crystal clear, for those who think that the sound is low I would like to tell them that they should play it with an equalizer app, it will shake your house, this amplifier plays my 12" inch woofer very well

NOT AN AMPLIFIER
VERY LOW OUTPUT. SPEAKERS ARE NOT FULLY UTILIZED SINCE OUTPUT IS LOW.. I AM USING THIS JUST AS A DAC NOT AS AN AMP. SINCE OTHER AMP HAS HIGHER OUTPUT FOR SAME WATT AND RMS SPEAKERS. NOT WORTHY
