Customers are mixed about the stereo of the audio mixing console.

I usually only review products if they are really good or really bad. This Mackie HM-4 is really good. I have a home music project studio, and I bought this Mackie HM-4 for use with my Audio-Technica ATH-M50x headphones and my Tascam US2x2HR audio interface. I did listening comparisons with my headphones plugged straight into the Tascam, and then straight into the Mackie, which was plugged into the Tascam. I was pretty amazed at how much of an improvement the Mackie made in sound quality through my headphones. The improvement was immediately clear.Everything sounds more clear and vibrant. All the frequencies are more prominent, especially the bass - the bass kicks are punchy and deep with some weight behind them. Without the Mackie, those same bass kicks sound flat and deadened. Low bass tone frequencies, like with bass synth sounds in Electronica music, are clear and very present. Midranges are clear, especially with vocals. And high frequencies are crisp but not harsh. And finally, I have not heard any distortion, even at loud volume. I really think these are good to lessen potential for listening fatigue if you are into recording. You don't have to work as hard to objectively listen.For $40 bucks you really can't go wrong with this Mackie HM-4. If you are doing recording or mixing and mastering, this is a must (or any other good headphone amplifier). Even if you just want to chill and listening to your music, these are still great for that, too. Right now I am going through my music collection and just chillin, listening to song I have heard a hundred times before, and enjoying them in a new way.Happy listening!
