    • Just Audio uHA-120 REV B - 

      Just Audio uHA-120 uses an internal more discrete configuration usually only found in larger desktop headphone amplifiers, to enable better alignment with the Just Audio's philosophy of delivering a natural, precise and uncoloured listening experience.

      This version is the new Revision B model which allows you to configure the unit to a higher gain setting for full size or hard to drive headphones or a lower gain setting for in-ear or easily driven headphones.

      Everything right down to the chosen components and the final PCB layout has been optimised for attaining the best possible audio quality. The standard fitted volume control potentiometer of the uHA-120 is of pro-audio quality which can be upgraded to a Vishay studio grade volume control pot.

      With a light-weight and durable design the uHA-120 with internal rechargeable battery is a high-quality portable amplifier that features everything you need to enjoy your music on the go.
