Behringer MicroAMP HA400

The Behringer MicroAMP HA400 is one of the most popular headphone amplifiers currently on the market. It is a 4-channel amplifier, which means that it can support up to four pairs of headphones. The MicroAMP HA400 is of the desktop amplifier variety, so it sits comfortably on your desk and gives you easy access to the volume control knobs.

Design and Accessories

The MicroAMP HA400 usually comes in two different colors – silver and black. The casing is made of aluminum, and the compact size allows for high portability. The packaging includes a 12-volt adapter to power up the unit.

There are six connectors on the side – one for the power supply, one for the audio input, and the other four for headphones. The MicroAMP HA400 uses 6.5 mm (1/4 inch) connectors for the headphones, so if your headphone jack is smaller than that, you will need to buy a cheap adapter before you get started.

When you’re in a recording studio, working with multiple artists at the same time, each of them will want you to adjust the volume in their headphones according to their preferences. Some will want to hear the backing track louder, while others will want it quieter. Each headphone input on the MicroAMP HA400 has its own volume control knob, which is a great feature not many amplifiers will offer you.

Pros and Cons

Pros
  • Affordable
  • Good build
  • Multiple headphone channels
  • Level control for each channel
Cons
  • Not USB powered

MicroAMP HA400 retails at a low price of $25, yet it gets the job done better than any other amplifier in this price range. Unlike other competitively-priced headphone amplifiers, this one uses its own dedicated power supply. This saves you the trouble of buying an adapter in order to power up your unit. The individual volume control for each pair of headphones will help the recording process immensely.

If you listen to music on your laptop and want to get better sound quality out of your headphones, this amplifier is the perfect choice for you. Its specs allow it to drive headphones with higher impedance (100 Ohms and above) without distorting the sound.

Because this model is built for studio headphones, if you use it in combination with headphones with lower impedance, you are unlikely to notice any difference in the sound quality.

Another important thing to highlight is how physically unstable this amplifier can be when used at full capacity. With up to six cables of varying length going out of it, they will often pull its weight and move it around the desk. In order to assure that the amplifier stays in one place throughout the recording session, you will need a reliable set of bumpers to ground it with.

The Verdict

If you’re in the market for a headphone amplifier and if the Behringer MicroAMP HA400 has what you need, then go for it. With support for up to four pairs of headphones and individual volume control for each pair, you will not find a better device in this price range. This model is a great piece of studio equipment, but you can also use it at home to further enhance your music listening experience.
