Brand New Professionally Built Objective 2 (O2) headphone amplifier with 16v 1000ma AC power supply and 2x nimh 9v batteries installed.
Often overlooked, many amps featured high output impedances resulting in poor audio reproduction, the O2 has an extremely low 0.54 ohm output impedance resulting in superior performance with any headphones.
Designed by the famous nwavguy.com this amp truly is the best value in headphone amplifiers. Works great with headphones from 16ohms all the way to 600 ohms. These amplifiers feature extremely low distortion and high current output capabilities. A built in battery charging circuit along with two pre-installed rechargeable 9v batteries make this amp a great portable option for audiophiles
