Hooked it up easily. quality was good overall. No real noise to speak of. It seems to be a little bright sounding, but slight eq change

I ordered this to use for a recording session and it delivered overnight. Fantastic value for the money. Plenty of volume and good, clean sound. Appears to be very well built. Highly recommend.

I find headphones are generally not loud enough. This is perfect for any you want to boost.

The sound quality isn't the best but it's not possible for the price. Solved my issue well and I'm happy!

The box is small enough to stash in the snake pit of wires behind the computer. All connectors are on the back panel, so the wires can be in a compact bundle (more compact than in-the-back out-the-front). This amp is so tiny, the weight and stiffness of 5 audio cables can drag it away. My intended usage is to get the cables and audio settings done and then just leave it behind the computer. The box needs to be anchored if I need convenient access to the knobs.I chose this amp for the claimed low noise, and for the input volume knob. I don't have lab gear to measure it, but the amp itself seems quiet. Of course, it can't do a miracle for bad audio cables. This amp makes a big improvement over the mess of Y-connectors I used to get computer audio to speaker amp, wired headphones, and bluetooth headphones.It would be nice to know the amplifier gain, but there's no published spec. I opened the amp to look inside. It seems well made, but it doesn't look like their pretty blue picture "5 PCS ROHM OPERATIONAL AMPLIFIER". It sure looks like 5 identical amplifiers with 5 identical knobs (amp circuit board photo).If amps are actually identical then I can get the amp gain from voltmeter measurements with the box closed. The gain for each of the 5 amps is +8dB, crudely measured. (Hey LZSIG, comment?)Measurement -- Computer runs Audacity to make 200Hz 0dB for amp input. Measure input Vrms. Adjust amp input and output knobs to get same Vrms at amp output, keeping knob rotations matched. This knob setting is 0dB gain (0dB knob setting photo). Next, set output knob to max and adjust Audacity to get back to same Vrms output: -8.2dB. Next, set input knob to max and adjust Audacity to get back to same Vrms output: -16.3dB.

The LZSIG amplifier is a good unit, with good construction. I had bad 60hz audio hum with this unit initially. I thought the unit was bad and ordered a replacement, but still bad 60hz audio hum. I tried another matching power adapter as another reviewer mentioned = no improvement. I finally found the source of the hum = my audio cables and/or the routing of my audio cables. The 60hz audio hum was coming from other cords (for example, power cords...) which were alongside my audio cables. I made sure my audio cables were all shielded, and I also routed all of the audio cables so that they were not running alongside or touching other cables, particularly power cables. HUM ALL GONE! BEAUTIFUL! GREAT UNIT, VERY RECOMMENDED! If you have audio hum, suspect and check/reroute your audio cables.

I was able to connect different plugs, 3.5mm and 1/4 in, and even connected both to types to 1 channel. Super versatile. Had to abandon this device when the power went out. Overall decent.

Compre este amplificador ya que el anteriore que tenia, un Behringer HA400 empezo a fallar de la nada, derrepente no sonaba, derrepente si, o metia mucho ruido.Empecemos con lo bueno:Un feature que me llamo la atencion es que tenia puerto USB-C, y que funcionaria con baterias portatiles.Decidi hacer una prueba de reproduccion continua, para ver cuanto duraba, y estos fueron los resultados:Un iPad tocando musica, conectada al amplificador, y esta tenia 4 audifonos conectados, con las perillas a las 12 del reloj y con un Powerbank de 5000mA.Esta empezo a reproducir a las 9 am exactamente y se apago pasaditas de las 7 am, es decir que tuvo un total de 22 horas de reproduccion continuas. Inicialmente pense que duraria aproximadamente unas 4 horas, asi que supero totalmente mis expectativas.Viene con cable y un cuadro para corriente. El cable pudiera ser mas largo, pero no es un dealbreaker.El boton que es Stereo/Mono esta un poco "flojo" pero una vez presionado. Para musica, la funcion de MONO no sirve porque practicamente te invierte la fase y se escucha como "lejos"Lo MALO:Suena MUUUUY MAL! Pense que eran mis cables y probe con varios, tanto de corriente como de sonido, etcpero no, es la caja que no sirve.Si presiones el boton a Stereo, suena mal pero suena, en Mono, suena mas mal y extremadamente bajo.Compare el sonido directo del iPad y parecia que me habian quitado unos tapones y cerilla hahaUn cambio totalmente drasticoLastima, prometia el aparato este pero pues no siempre funcionan.Espero que esta informacion les sea de ayuda.
