Behringer MICROAMP HA400 Ultra-Compact 4 Channel Stereo Headphone Amplifier

First off, I'm not using this device the way most people would use it, e.g. multiple headphones. In other words I use this device to distribute my digital music, via my DAC (digital to analogue converter), to four of my five mini-amplifiers. And to this end it works beautifully, it has a volume control for each of the four stereo output channels, as well as an overall volume and balance control and, unexpectedly, more headphone input sockets on it's back than I could ever use (these sockets are not displayed on Amazon).That said, the sound conveyed is clean and detailed with, on rare occasions and to my ears, a slight brittleness in the upper frequencies but nothing I cannot live with. Overall, I find this device easy to use, more controls than I could ever want (I'm a set and forget kinda guy) and it delivers what I bought it for, i.e. distributing streamed music from my DAC to my mini-amplifiers.However, there are a few things I am not partial to, such as the flashing diodes, the plastic look and feel of the device and the fact that it's bigger than I thought it would be. But again, these little nit pickings are nothing that I cannot live with because the overall functionality, usefulness and sound this device conveys far outweighs it's aesthetics.Finally, I would say that this device is well worth the cost, at under £40 (I paid £39.99), and recommend it to anyone that has to pass a stereo signal onto four other devices.

excellent product and cheap too

Quickly delivered by Amazon Prime as ever. Great price compared to other online sources.The headphone amp is very small (see photos with hand in shot for scale) but came neatly packaged with the required 12v dc adapter for a UK socket.I am using it to drive my higher impedance (80 Ohm) Beyerdynamic DT770 Pro headphones and although the maximum volume is not ear splitting it is a significant improvement than just being driven straight from my MacBook Air M3 headphone socket.All 4 amps work independently and don’t seem to be affected if all used at the same time. Good clean sound with no distortion even at max volume.For the price and the size it’s a great piece of kit.

Well made and noise free. Its ideal for a small studio.

I sing in a covers rock/pop band as well as sing jazz, swing and show tunes as a soloist event singer, using pro backing tracks.The problem I was experiencing was that in the band, the drummer was so loud, I couldn't hear myself even with a 300watt wedge monitor under my nose, and with the solo stuff, I need to sing as background and couldn't always be near my PA system to hear well and the monitor was too heavy to lug around. I opted for in ear monitors, but my mixing desk has pre-amps for mic only, so my in ears needed a boost.This bit of kit is excellent, gives you complete control because of the separate volume knobs for mix and mic only, so if you want 'more me', you can have it. The only down side is that there are a lot of cables in and out, which if you are a presentation neat freak like me, can be messy and difficult to contain and hide, but the box itself is lightweight, small and compact.I would recommend this product if you are looking for a little more control and flexibility over your personal reception of sound, especially if this settles your confidence when performing.The item arrived promptly, was well packaged and the manual is easy peasey to understand (I'm a non technical girlie - even I coped !)

Ok Drummers! Read this, this unit has changed my life.I have had all sorts of monitors but came across this £18 wow! I have a mic from my bass drum going into this then out to the PA I then have a line I. From the the PA what I get is a complete mix through my headphones I use the ones I got with my I phone but bought an extension cable just to give more room to move. They work perfectly I get the mix from the PA which I have a volume control for and I get my kick drum which I can also control from that's volume. Live it is amazing I have a perfect mix of everything in my ears the headphones dull the rest of the drums and cymbals but it makes you play better IMO and when the gig has finished no ringing ears it's amazing and hearing the kick drum cut through the mix so well makes you play tighter. Don't mess around buy it it's £18 you get the power control all you need is a jack for the mixer and 2 mic leads our keyboard player has one and does the same with his vocals so he can control the volume of his singing also having a perfect mix of what's going out front.EPIC!

This is a great little Headphone Amp for the price. I know that James Hype, a platinum selling artist, owns and uses one of these.Personally I use mine for 2 purposes. Firstly to split the audio so I can have multiple listening devices but the main purpose is to power my DT990 Pros which I prefer to use a dedicated amp for (even though the new M1 Macs have great amps in them already).As of noise, it’s definitely there. It’s not horrible and I was actually very impressed for the price. For reference my Pioneer DJ Mixer produces more noise from the built in headphone amp then this. I know that’s a different purpose to producing music, but even when producing music, the noise isn’t too destructive.I feel like judging the noise is difficult with this, I put 3 stars For Noise level because it is there but then again the price… at the end of the day if you hate noise so much then invest in a $100 Headphone Amp, not a budget one.If your just looking to power high impedance headphones, or you want to split audio, this is a great purchase. If your a producer or DJ this is a great purchase. If your an audiophile then the noise will be a problem.

Great little headphones amp 4 way brilliant for my home based studio
