Graham Slee Voyager Headphone amplifier 

You won't believe the difference Graham Slee Voyager portable headphone amplifier can make to your music when out and about, it is simply stunning. Coupled with an iPod or other portable music device and a decent pair of headphones, this amplifier gives precise, spacious sound quality with excellent detail and bass extension. A contour switch on the side compensates for the weak bass from some portable headphones by boosting low frequencies to give a more satisfying sound.

Powered from a single 9V PP3 battery, one to three months usage is assured due to the high-efficiency circuitry employed. Top quality components are fitted including ALPS volume control and switches, giving dependable reliability and superb sound quality. The black ABS case is drop proof and durable, whilst the battery is easily changed due to the snap-on, snap-off design case work. The amplifier can be powered from USB once you get home or at work from your computer, or via the supplied plug-top power supply.
