Behringer MICROAMP HA400 Ultra-Compact 4 Channel Stereo Headphone Amplifier

Great little item. I needed it to boost the headphone out on my CD/DAB radio. Really improved output. Easily to set up and no noise. It's not what it was designed for really and so my set up can't be classed as HiFi but it's good enough for me.No distortion, easy to connect.

Honestly, with change out of twelve quid, what can you say? A true four-channel stereo headphone amp splitter that works well.

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.

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

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.

Serious mains hum. Fine for recording but not for mixing. Cheap though.

excellent product and cheap too

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