Urgent order items are products that we do not normally carry on stock, but they are typically held on stock by our European suppliers. Depending on availability, we will seek to order these products quickly, when we have an enquiry. They can therefore be subject to quicker availability times than "Special Order" products.
Special Order items are those that are most often built to order. For these items, we tend to experience longer lead times as we negotiate them into the production line with our suppliers.

When it comes to delivering high-class sound through the output of modern devices such as laptops or smartphones, they simply don’t have enough power to reveal the true potential of today’s headphones. Head Box E, stepping in between the source and your headphones, has enough power to unleash the highest quality sound from almost any pair of headphones. Featuring one RCA input for a source of your choice and another RCA output for signal passthrough, the micro-powerhouse keeps things simple. The front panel plays host to two headphone jacks, one 1/4 inch for hifi headphones and one 1/8 inch for modern personal listening products. Both of these outputs can be used simultaneously for shared listening experiences, if desired.
With a powerful discrete headphone amp design, the Head Box E’s unusually high output power will deliver top-quality sound and plenty of volume, even for those who wish to listen at loud volumes and use difficult-to-drive headphones. Featuring a rich and full sound with plenty of dynamics and transparency, the fully discrete headphone amplifier does not use cheaper integrated chip designs, instead opting for fully discrete electronics in an expertly laid out circuit board design. The result, not only fantastic power metrics with clean measurements, but also a long product life-cycle, as maintenance, service and repair can be ensured for years and years to come.
Only the best possible components were used to create this one-of-a-kind headphone amplifier. With a fully metal casework to effectively protect it against electromagnetic interference and vibrations (which can cause unpleasant listening experiences), and simple yet sturdy machined aluminium controls offering a reassuring and easy user experience, the Head Box E is true Pro-Ject quality squeezed into an effortlessly integrable chassis size.
Henley Says...
No matter how good your headphones are the chances are they're being limited by your source. If you listen from a phone or laptop or something without dedicated amplification then you're throttling your musical experience. The Head Box E is a deliberately compact unit that solves this problem - unbinding your beloved cans to really perform as they were always meant to.
