KMA Machines - Stereo Headphone Amp
Freedom to create… wherever and whenever!Creativity is an actual superpower… Seriously! If you don’t think that pulling music from thin air simply by moving your hands across frets and strings, keys or even hitting things in time isn’t overpowered magic, then we don’t know what to say anymore. You’re a sonic superhero (deal with it!) and therefore gear should never become your kryptonite and hinder your creativity. It should allow you to express yourself freely exactly when needed.
This is why KMA made the STEREO HEADPHONE AMP – a simple, compact and great-sounding dual headphone amplifier with AUX in, Bluetooth, pass-thru as well as Stereo Ins and Outs. Meaning you can practice, explore and create in full ear-gasmic stereo. This new little box in KMA’s utility line will add high-quality headphone monitoring to any rig, wherever and whenever you want it.
