Ztella II comes with a completely new balanced output headphone amplifier design. It provides tremendous output power to your headphone. With a default output at 2.2Vrms and a boosted output (by pressing the side toggle button) at 3.3Vrms, it drives your headphone to its true potential and delivers an unprecedented audio experience.
 

Ztella II follows the similar single cable design in a clean and elegant configuration. The chassis is made from aluminum in matte black color, unifying in one single color tone. The LED indicators clearly shows you the sampling frequency and boost status information. This balanced output version brings your music enjoyment to the next level.
