Pro-Ject Head Box E Micro-Sized Headphone Amplifier – Silver
The Pro-Ject Head Box E is a compact yet powerful audiophile-grade headphone amplifier designed to reveal the true potential of your headphones. Many laptops, smartphones, and other modern devices struggle to deliver the necessary power for high-quality listening. The Head Box E solves this by providing ample drive and exceptional clarity, unlocking rich detail, deep dynamics, and an impressively transparent soundstage.
Equipped with a single RCA input, it connects effortlessly to your chosen audio source. On the front panel, you’ll find two headphone outputs – a 6.35mm jack for hi-fi headphones and a 3.5mm jack for portable models – both of which can be used simultaneously for shared listening sessions.
High-Performance Discrete Circuit Design
Unlike amplifiers built with cheaper integrated chips, the Head Box E uses a fully discrete design with high-grade components. This approach ensures low distortion, reduced background noise, and the ability to power even the most demanding headphones without compromise. Its robust output handles challenging impedance loads with ease, delivering full-bodied sound even at higher volumes.
Premium Build Quality
The amplifier’s full metal housing shields it from electromagnetic interference and vibrations, preserving sonic purity. A beautifully machined aluminium front panel adds to both durability and aesthetics, while the small footprint makes it ideal for desktop or hi-fi rack placement.
