Monitor Audio Jack

I recently upgraded my studio with a 16-in/16/out audio interface, but with no headphone jack and no monitor control. This little box solved my monitor control issue perfectly. Extremely transparent to my ears, very solid build, all the controls have a nice feel to them, and great looks. The wood sides are more of a walnut color than what's shown on the website, which was perfect. Highly recommended.

Does its job! Using for sending audio out of a headphone jack to a translator.

I'm a complete newbie with video and am using this on a Sony a6300 plugged directly into the audio jack. A definite improvement over the built in mic. It's lightweight, but sturdy...easy to carry around...

I needed this for the RODE Wireless GO 2 system (to output audio through USB and use the 1/8th jack to monitor the audio signal.) The price is high, but it's the only one I could find online.

This camera is perfect, no issues with stuck batteries, no issues with the audio jack, no issues with the battery indicator, I got a solid unit

Just needed something to merge the two audio cables into the PC line-in jack. This worked well, and the cable length is good.

I used this hooked up to my iPhone 6+ in the past, but since I upgraded to the 7+ with no headphone jack I've been using the mic hooked up to an audio recorder for my DSLR video (the recorder has phantom power). I use the extension cable and rode adapter for standard 3.5mm input and it works great. The sound is as good as I'll need it to be for interviews. I'd only upgrade to a nicer mic if this one breaks.

My Vizio TV doesn't have a headphone jack, but it does have line out jacks for audio. This little headphone amp is the perfect solution for this situation. Totally worth $$--get one.

Bought this for my digital piano. It came with two audio jack adopters (6.35 and 3.5), the larger of which fit my piano. Overall, It's built sturdy with metal frames. The ear pieces provide good sound proof and also fairly comfortable for prolonged usage. Sound quality, combined with the sound-proof ear pieces, feels pretty good. Delivers high details across the spectrum.

It does exactly what I need. I have a high end stereo receiver and speakers connected to my iMac computer analog audio output (headphone) jack. The receiver also is connected to several other analog audio sources. I have had persistent issues with hum in the audio from the computer. I tried all sorts of things, floating grounds, reversing plugs etc and nothing worked. putting the HE-18 in line with the computer completely eliminated the hum with no adverse side effects to the audio quality. I really appreciate the flexibility of all the various input and output connections. I now have a convenient extra port where I can plug in headphones for private listening when needed. (Unlike the idiots at Apple who put the headphone jack on the back of the iMac. What were they thinking?) The engineer who designed the HE18 deserves a lot of credit. He really did his homework.
