I use it to transmit the signal from the laptop headphone jack to 4 amplifier stations. It's OK with the volume on it at 1/2.

Handy device for output to multiple devices - amplifier, or multiple amplifiers, handset. Saves the audio contact of the computer from wear by frequent insertion and withdrawal of the cable contact. The disadvantage is the loud noise of the device, especially with the amplifier or audio speakers. I used a headset, audio PC speakers 2+1 and an amplifier up to 100 W at the same time. There was less noise with the PC speakers, with an amplifier with 80 W speakers there is more noise, if it is not played, the music does not play. The basic use would be MIDI keys with a computer in a DAW, or with sound modules separately without a PC.

After four months, the USB power socket literally fell off and sometimes makes a noticeable whistle. It's fine for the price, but I'd rather spend a few hundred more and go for something else
