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!

I am feeding this headphone amp from the headphone output of a computer and it works very well. I use a cable with a stereo phono jack to feed the input of this headphone amp and a 3.5 mm stereo plug which connects to the headphone output of the computer. I have read various reviews of people who said they had hum or were missing one channel. All of these people don't know how to use it correctly. I had this headphone amp working in two minutes and the audio that it delivers is exactly the way the original recordings sounds at any volume that I care to use. The quality of the pots on this headphone amp are the same as on other pieces of Mackie equipment which is high quality. If you use the correct stereo cable, you will have no problems. When I bought this headphone amp, I also bought the correct cable. It's only a headphone amp and setting it up is very straight forward and not rocket science. I'm very happy with my purchase of this headphone amp.

Great value! Not perfect but solid build for the cost. I read reviews stating there was noise but I placed mine away from other devices and cables. It was silent. When placed near my other gear, there was interference, which is normal.

Incredibly useful piece of equipment! If you need more than one headphone feed from your device, the Mackie is a great solution! I use it with a Tascam Model 16 so my voice actor can monitor himself in the vocal booth while I am monitoring the overall recording in the control room. Get the appropriate cables for your situation as far as connections and length and enjoy recording! Each output has its own master level

I'm a record producer and mixing engineer with over 35 years of experience and I've worked and/or collaborated with multiplatinum talent, Grammy winners/nominees and people with Billboard #1 hits over the years. I can say safely this is the best headphone preamp on the market. Mackie is a very well-known brand for their top notch mixing boards, and this meets their standards. The volume knows are very smooth and have a sturdy, almost weighted feel to them. Other headphone amps I've had, the volume knobs or sliders usually felt cheap and would crackle when you changed the volume. NOT this one. The sound quality is absolutely pristine with no noise, no crackle, no hum. I use AKG Q701 Quincy Jones signature series headphones, which sound amazing but run quieter than other headphones I've owned. This preamp has saved the day. It gets so loud that I have to be careful not to turn it up too loud so I don't hurt my ears or damage my headphones, which is exactly what I was looking for. You can listen quietly and it sounds perfect but if you need loudness (due to having quiet headphones, like me, for example), this will absolutely DELIVER. Emphatic 5 stars from me!!
