Mackie HM-4 4-Output Headphone Amplifier

I used this to split the headphone output from my audio interface into four. I was able to compare the sound differences of four types of headphones. Each output has independent gain control, allowing for balanced volume levels.

There are minor scratches on the corners and sides, but the robust body ensures no operational issues.

Comes with the original box and accessories.
