I tried to return it to the store or exchange it for others, even with a surcharge, it didn’t work out, they said the hiss is a design feature of the amplifier and nothing can be done about it, I didn’t find a solution on the Internet either. Got pros: The sound, for their price, is of course excellent, smooth, clean, ideal for listening to music at the computer, taken as multimedia. Got cons: 1. They hiss, at any non-zero volume, and they hiss strongly, even if you listen to music, there is still hissing in the background, so you have to listen louder than you would like to not hear it 2. The sound of turning on, what genius invented it ?! it’s not clear, but even with the volume turned down to zero, they yell at full power, it’s impossible to turn it on early in the morning or at night, they wake everyone in the apartment
