Product Description

When it comes to delivering high-class sound through the output of modern devices such as laptops or smartphones, they often fail to reveal the true potential of today's headphones. The Head Box E has enough power to unleash the highest sound quality from any headphone. It features one RCA input for a source of your choice. The front panel offers two headphone jacks: one 1/4 inch for hifi headphones and one 1/8 inch for modern head- and earphones. For shared listening experiences, both outputs can be used simultaneously.

Its unusually high output power will deliver top-quality sound and enough volume, even for those who wish to listen at loud volumes and use difficult-to-drive headphones. The Head Box E features a rich and full sound with plenty of dynamics and transparency.

The fully discrete headphone amplifier does not use cheaper integrated chip designs. It uses fully discrete electronics in an expertly laid-out circuit board design, resulting not only in fantastic power metrics with clean measurements, but also ensures a long product life-cycle, as maintenance, service, and repair are ensured for years to come.

Only the best possible components were used to create this one-of-a-kind headphone amplifier. The enclosure is fully made out of metal to protect it effectively against electromagnetic interference and vibrations, which can cause unpleasant listening experiences. The front panel and control elements are made out of beautifully machined aluminium.

Due to its low price combined with versatility, power, and high-quality sonics, the Head Box E is an absolute audiophile bargain! A new reference headphone amplifier in the budget market!
