Pro-Ject Head Box E Micro-Sized Headphone Amplifier Silver

Pro-Ject Head Box E Micro-Sized Headphone Amplifier – Silver | Compact Audiophile Performance

Unlock the Full Potential of Your Headphones

The Pro-Ject Head Box E is a high-quality, micro-sized headphone amplifier designed for discerning listeners who want to experience their headphones at their very best. Many portable devices and computers lack the power to drive premium headphones properly, resulting in flat, underwhelming sound. The Head Box E delivers the power, clarity, and dynamic range your music deserves – all in a compact, beautifully built unit.

Whether you’re listening on studio-grade over-ear headphones or portable on-ear models, the Head Box E ensures every note is delivered with rich detail, deep dynamics, and a natural, transparent soundstage.

Discrete Circuit Design for Superior Sound

Unlike basic amplifiers that rely on inexpensive integrated chips, the Head Box E employs a fully discrete circuit design with high-grade components. This results in:
• Lower distortion for cleaner, more accurate audio
• Ultra-low background noise for greater detail
• Effortless power delivery for headphones with higher impedance loads (8–600Ω)

Its robust output stage ensures full-bodied sound even at higher volumes, handling demanding audiophile headphones with ease.

Flexible Connectivity

The Head Box E integrates seamlessly into any setup with a single RCA input for your source and an RCA loop output for easy connection to other components. On the front panel, two headphone outputs – 6.35mm (¼-inch) and 3.5mm – can be used simultaneously, making it perfect for shared listening.

Premium Build, Compact Footprint

Encased in a solid metal chassis, the Head Box E is shielded from electromagnetic interference and vibrations, preserving sonic purity. The precision-machined aluminium front panel adds both elegance and durability, while its small footprint makes it ideal for desktop use or discreet placement in a hi-fi rack.
