Graham Slee Voyager



Durable For A Long Life On The Road

What makes the Voyager so popular amongst hi-fi headphone amplifiers is its wonderful big headphone-amp sound, and that it can take the knocks!

Unlike those ‘blingy looking scratch-magnet’ headphone amps, the Voyager’s rugged contruction helps it keep its appearance much longer.

Another simple but great benefit is the ease of battery replacement – its E-cell power source is available in lots of shops. Not that you’ll be replacing it all that often, as it lasts for up to 50 hours continuous playing time!

The Voyager is supplied with battery fitted (as required by the “Battery Directive”), and is also supplied with a mains power supply for non-mobile use. Plus, it can pick up its power from a 5V USB source!
