Review: Great but weak way to combine output from two different headphone sources - This was the only small, portable device like this that I could find so I bought it to combine the output from my iPad and my laptop so I can be viewing instructional videos on the iPad while doing the work they're talking about on my computer and can work right next to someone and they don't hear a thing. BUT (and it's a huge BUT) the sound is greatly diminished because it's a passive mixer (i.e. it doesn't have any power). The way the wiring has to be done to prevent the signal from one device from feeding into the other device requires resisters and capacitors which all contribute to reducing the volume. I solved that problem by purchasing a very small portable headphone amplifier with rechargeable batteries, the NeoTeck Headphone Amplifier. I take the combined output from this mixer and run it into the headphone amplifier and plug my earbuds into the headphone amplifier's output and I get great volume. The documentation for this headphone mixer does very clearly state that the signal is "attenuated" -- many people won't know that means "weakened" -- why they couldn't just say the output is very quiet is beyond me. But as they say, forewarned is forearmed. I am giving this 5 starts because it is very small, very convenient to move around and it does the job with a clean output signal that combines both inputs. And it has a level control for each input so that I can balance them to get the sound I want before it makes it to the headphone amp.
Review: Did do what I needed, - Great construction, well built, and worked. connected Audio output of Carpuride Apple play unit ( Also bought on desertcart 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 desertcart. 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 desertcart, hooked to DAC, Also bought on desertcart, as I am taking pictures with phone

### ⭐ did not work - no volume
*by J***S on February 9, 2023*

Saw a few 1 stars about no volume or sound and a few that said it worked great... Well, mine was in the "did not work" category. Well made block of metal, but could not hear anything . Headphones connected thru to PC and electric guitar (using pre-amp) connected to mixer...no sound
