Modern devices like smartphones or laptops fail miserably at producing high-quality sound. They lack the power to unleash the true potential of today's headphones. The Head Box S2 features an RCA input for a source of your choice. On the front, there are two headphone jacks: a 6.35 mm jack for HiFi headphones and a 3.5 mm jack for modern headsets and earbuds. For shared listening experiences, these outputs can be used simultaneously. The 725 mW output power delivers high-quality sound and enough strength to satisfy even those listeners who enjoy high volumes. The Head Box S2 offers a rich and full sound with ample dynamics and transparency.

Only the highest quality components have been selected to create this unique headphone amplifier. The housing is made entirely of aluminum to ensure the highest aesthetics while effectively protecting against vibrations and electromagnetic interference that can cause undesirable sound experiences. Compatible upgrade power supplies: Accu Box S2, Accu Box S2 USB.
