A compact headphone amplifier that supplies clean, low-noise power to demanding headphones. Ideal for listeners seeking fuller dynamics and clearer detail from turntables, laptops and phones without a bulky hi-fi rack. Is the Pro-Ject Head Box E Headphone Amplifier the right upgrade for small listening spaces and versatile source setups?
⚡ At a Glance
- • Sound Signature: Transparent, detailed presentation with very low noise and minimal distortion
- • Best for: Audiophiles and home listeners who need clean amplification for demanding headphones
- • Not ideal for: Users who require built-in wireless streaming or hands-free microphone features
Fully discrete amplifier design delivers high output power with low noise and low distortion. Dual headphone outputs and a bypass RCA loop output allow easy integration with turntables, external amps and portable sources.
Clean, powerful drive – thanks to a fully discrete amplifier design and high output power
A fully discrete amplifier topology keeps the signal path simple and robust, producing strong drive capability while avoiding shared integrated stages. Premium components and careful circuit layout reduce noise floor and distortion without adding unnecessary circuitry.
High-output capability ensures demanding headphones reach their dynamic potential, while low noise preserves fine detail during quiet passages. Listeners gain clearer dynamics and improved headroom on complex material.
Flexible listening options – with dual 6.35mm and 3.5mm headphone jacks usable simultaneously
Separate front-panel outputs are wired to the amplifier stage so both full-size and portable headphones can be connected at once. The outputs are arranged to maintain signal integrity when sharing the amp between two pairs.
Easily compare headphones or share listening with a friend without unplugging anything. One setup works for a wide range of cans from portable models to large, power-hungry headphones.
Seamless system integration – with a bypass RCA loop output and single RCA input
A single RCA input accepts line-level sources and a bypass RCA loop output passes the incoming signal on to other equipment without altering the signal path. The metal housing and aluminium front panel help shield against interference.
Hook up a turntable, laptop or phone and send the same signal on to an external amplifier or recorder while retaining a clean headphone feed. The compact, shielded build suits small racks and shelves.
