I'm a praise team worship leader and we use these devices as in ear monitor systems. We love the price point as church budgets usually need creativity to accomplish greatness. All 6 of our musicians used them this week (drummer, bass, electric guitar, piano, vocalist and acoustic guitar) and not only did they help each member hear more clearly, the MA400 drastically cut down on stage noise by eliminating our wedge monitors.
My only complaint is that we had to turn the volume up all the way on the mixer board as well as the MA400. I'm not so sure these devices "amplify" the source very well. That being said, we have no problem cranking on the volume as it is probably a blessing in disguise. We didn't install limiters on each channel so I hope the lack of amplification will in the end protect our hearing.
Overall I gave this product 5 stars but would have liked to rate it 4.5. Hope this helps!

I planned to use this product to amplify the volume of my in-ear monitors that I use on-stage. I also wanted the option of adding some additional guitar volume by using the mic input. I expected this to be an amplifier, but it actually DECREASED the volume of my headphone signal, by a large margin. Even at maximum volume, the headphone signal was a lot quieter with the MA400 than without. As far as I can tell, it may be a mixer, but it definitely is NOT an amplifier -- at least mine wasn't. Sent it back.

Comments about Behringer MA400 - MICROMON Miniature Monitor Headphone Amplifier:
So happy with the first unit, I had to buy a second one for my home studio...Have use in live situations as well and the sound is pretty descent went connected to an AUX coming from the mixing board. It is not that great by itself if you're rehearsing or monitoring a Bass or guitar by itself. Overall is a great little box and one of the cheapest on the market.

Comments about Behringer MA400 - MICROMON Miniature Monitor Headphone Amplifier:
The Micro Monitor has a very clean sound with lots of headroom. I especially love the stereo/mono switch. This allows me to send a mono signal from an auxillary send, but have it in both ears while in mono.

Comments about Behringer MA400 - MICROMON Miniature Monitor Headphone Amplifier:
The vocalist was confused about how load her voice was coming through the main mix at the hall. It affected her ability to perform. We plan to do a duo with vocal and guitar. The monitors in the place are a bit out of phase with the echo in the hall. The plan is to bypass all this up front and perform in a bubble as it were.

Comments about Behringer MA400 - MICROMON Miniature Monitor Headphone Amplifier:
This is another great product from Behringer. I use this to control my headphone volume while editing video on the PC. My process involves playing unedited clips and then reviewing clips placed in context, and these have two very different volume levels. Until I got the Behringer MA400, I was constantly setting volume levels by using the mouse--a tedious process. Now it's very easy to adjust volume with the simple, old-fashioned volume knob on the MA400.
The MA400 is solidly built, mostly of metal, with firm controls. It seems to add no noise to the signal, which is as clear as that coming directly from the PC Sound Card.
The only downside is you have to plug and unplug the MA400 to "turn it off." I leave mine on most of the time, but a switch would have been nice.
Otherwise, and for my use, this was a perfect purchase.

If you are looking for something that boost the volume strength, you better look elsewhere. I found this is suitable as volume control rather than signal booster. But still a good, well-built product. Thanks!!

Comments about Behringer MA400 - MICROMON Miniature Monitor Headphone Amplifier:
We were looking for an inexpensive monitoring system for a 3 piece band that plays weekly in a small venue. We bought one Behringer MA400 for the guitarist/singer, and are now outfitting the whole band with them.
It is simple and effective. Letting you level the monitor mix and your own line independently is very useful. There are no bells or whistles, but what the Behringer MA400 does, it does well. And you can't beat the price!

It looks good and has the necessary connections for what it was made for. The amp is sub par though. It can't drive any headphones loud enough at all. My iPod is louder than this thing with the same headphones. If its LOUD you are looking for look on elsewhere.

Comments about Behringer MA400 - MICROMON Miniature Monitor Headphone Amplifier:
Much cheaper than wireless monitor system, and it works great.
I can send one monitor mix to all vocalists, they can add in their mic through the line throughput, and dial in their own mix from those two levels.
I want to mount this on the mic/music stands, but I can't find a mounting kit for it. It does have two screw-holes on the back, which I assume are for mounting, so I may have to rig something up.

I use this amp when I have a gig where I want in-ear monitors and the system only has floor monitors. I just plug the floor monitors into the MA400 and plug in my in-ear headphines. It is an inexpensive and effective solution when in a pinch. I keep this with all my gear. I used it the other night playing drums on a gig and it gave me the volume control I needed.

Haven't had it that long to comment on quality but seems durable. Everything works like it should. Compared to Rolls PM50S, does the same thing $10 or so cheaper with no tax[...]
