Great product when used correctly
I used it originally to introduce a Bluetooth adapter to my speakers while keeping my Chromecast connected to the speakers as well. I did have a buzz with the ground noise isolator connected but when I removed it, the buzz went away.Now I use it to connect both of my computers and Chromecast to the same speaker system. No hum, buzz or static sound.

Reduces volume by 70-80%, totally useless.
Waste of time. Connected two outputs to it and volume goes down by a lot even with controls all the way up. Useless.

Did do what I needed,
Great construction, well built, and worked. connected Audio output of Carpuride Apple play unit ( Also bought on Amazon W103 Pro) to one input, and output of i phone through a Dragonfly cobalt DAC from an i phone 15 to the other , to the Aux in on a 2015 Honda Oddness. Also ran the output through a line filter also purchased through Amazon. Now I can combine signals from Both inputs, adjust Volume levels, and hear Lossless music from i phone, and directions at the same time from car play, avoiding the Loss in Music you get from, Wireless, and gain the HI Res, lossless you get from an external DAC. Can’ take picture with Phone in Wireless charger also bought on Amazon, hooked to DAC, Also bought on Amazon, as I am taking pictures with phone

Needs an amplifier.
Does what it says but the sound is too quite. I ended up just getting a mixer with the amplifier built in.

6 months in, working great with computer audio + Chromecast Audio
I’m using this device to drive one set of powered speakers from two stereo line level sources: my computer audio output, and a Chromecast Audio device. I did not get the buzzing that apparently shows up in some applications, so I did not have to follow the instructions for getting rid of the possible buzz. Six+ months in, there is no evident damage to either audio source. It is super convenient to be able to use the speakers for two purposes simultaneously. As other reviewers have noted, there is some coupling between the two volume knobs (e.g. if you max one of them out you will silence the other) but practically speaking I have no trouble getting the volume and the relative volume that I want. While listening to Chromecast Audio, I can hear the computer’s audio output too, clearly and as loud as I want to set it to.

Works well with one exception
I needed a solution for mixing (2) PC audio outs into one signal that I could connect my headphones to. I decided to give this device a try despite some bad reviews.It turns out that this device works really well, has a nice metal case, inputs are metal and feel solid and the plastic volume knobs feel robust. There’s no line noise, it does indeed mix the channels as advertised and it supports stereo for all inputs/outputs (I did not test reversing the path as the docs say is possible). One thing you need to keep in mind is that all channels need to already be amplified- if you choose an unamplified source the volume will be very low. On Windows 11, I had to choose my “Speaker out” option to get an amplified out from the Display port audio.The only issue is that, once the channels are mixed, only “Level 1” volume knob works and it reduces both inputs together. You can’t use both knobs to reduce each input independently. This isn’t a major issue for me, but seems like a miss on their part. I also had a stereo cable and a stereo adapter that came through in only one channel for some reason. I did find 2 cables that worked perfectly, so those other cables may have been faulty.Bottom line is that this device is great for my problem where a proper mixer could cost hundreds of dollars, but would be complete overkill. This device, being passive, doesn’t introduce any audio buzz or sound quality reduction so going high end for solving such a simple problem is a waste of money.

Soft in volume.
Volume just was not there. It was too soft to hear even with all the other volume knows turned all the way up.

Great for sharing one set of speakers
I had been looking for a combiner Y cable for two computers connected via a KVM switch to use one set of speakers. My KVM has audio support, but I wanted to have my sound between the two computers combined into one and sent to the speakers. This device works perfectly for this. Every other Y cable I tried failed to deliver. Some didn’t work at all, some only worked for one computer, and some gave me mono audio.

This product works as it says. It is meant for line level devices and so higher impedance low level devices like guitars may give odd responses such as the other channel control having some effect or a muted sound. (the guitar was handy for a quick test) The device is stereo and will also work with balanced lines or a mix of balanced and unbalanced but not a mix of balanced and stereo.

Works exactly as described. I used this to combine a drum trigger module with my iPhone and it works perfectly well. However, the attenuation of the signal is very, very high and therefore too quiet to use with earphones or headphones. Rather than spend additional money an a headphone amp, I decided to return this and buy a battery powered mixer which does exactly the same thing, albeit for twice the price; but still significantly cheaper than buying a headphone amp in addition to this.

Sto imparando il pianoforte su una tastiera digitale, e ho necessità di usare le cuffie perché mi cimento di notte. Siccome seguo un corso video scaricato da YouTube, ho necessità di suonare contemporaneamente al maestro, per verificare la corretta scelta delle note e soprattutto la correttezza e regolarità del tempo. Avevo quindi necessità di portare in cuffia non solo il suono della tastiera ma anche quello del maestro.Questo mixer mi va benissimo: sia l’uscita audio del tablet col video sia quello della tastiera sono sufficientemente potenti da pilotare, una volta mixati. le mie cuffie monitor professionali Sony MDR-7560.Il mixer è passivo, cioè non ha amplificazione, anzi ha alcune resistenze (e forse condensatori, non l’ho aperto) per cui per mixare segnali di basso livello, come quelli provenienti da due microfoni, potrebbe non andare bene anche se devo apertamente dire che non ho provato.Confermo che il mixer è stereo, una cosa che mi pare non risulti dalla descrizione.Nel mio esemplare la regolazione del volume è perfettamente separata per i due canali, a differenza da quanto riportato da altri utenti: probabilmente il circuito è stato modificato dopo quelle recensioni.Perché metto 4 stelle e non 5? Per il prezzo! Un mixer passivo è di una straordinaria banalità circuitale, di costo veramente infimo. Però la “carrozzeria” è davvero deliziosa, in alluminio satinato, e quindi 15 euro li avrei pagati volentieri. La differenza tra 15 e quanto pagato secondo me vale una stella.

My first impression upon holding it was I was very impressed with how solid it felt. The volume knobs feel solid and satisfying and the metal shell feels thick and durable.Playing audio through it worked great, with no loss in quality or noise introduced. However you must keep in mind that a passive mixer like this will reduce the volume by about half, so I recommend pairing it with headphones that are easy to drive or in ear monitors.It lets me do exactly what I wanted to do, which was route audio from my laptop and Steam Deck to a single pair of headphones so I can binge watch my favourite TV shows while playing games.
