It's simply breathtaking how it transforms the sound, adding warmth, sparkle and a sense of three-dimensionality that wouldn't be out of place in a separates system many, many times its value. Stacey Kent's vocals took on such a creamy smooth texture that I thought I was listening to a valve amp. ...as well as going loud, this amp delivers dynamics, and it delivers them by the JCB scoop-load. ...if a fuller sound is your thing, or your headphones are a little lean, you can correct this by flicking the Contour switch on the side of the Voyager. Unlike equalizer settings on most MP3 players this boosts the bass without warping or degrading the sound quality

To test out the theory that the Voyager can bring to life even the most generic of headphones we used it in conjunction with a variety of standard headphones, namely: the generic Samsung headphones supplied with the Galaxy Note 2 and a set of official idevice headphones. Audio quality through both sets of headphones normally was average, however once connected to the Voyager the transformation was instant. Audio clarity and depth was enhanced dramatically, hard to believe we were actually still listening to the same audio through the same set of headphones. Graham Slee have all the ingredients of a truly superb piece of audio equipment – if they were baking pies they’d be the best in the business. As it happens, they are not pie makers and the Voyager is a real best in the business audio contender.

Sittin here in the sun listening to the Voyager and now I know what the fuss is all about. Astounding quality. The most analogue headamp I've ever met. Kills my old Fostex hp p1 and the mooted Centrance Hifi M8 to kingdom come. My old Fiio E11 is in the recycle bin too. No hint of digital hash..wow. massive sound stage. Clarity is sublime. Where's the distortion gone? Black background and no noise i can hear. Senn Momentum sounds beautiful now. Senn HD 650 and Audeze stupefyingly sound great too from such a small box. All in all a mini Novo!!!! Bravo Graham and his gang...once again.

I didn't know what to expect but I have been amazed at the extra warmth & depth that I now have together with the increased separation & clarity that the Voyager brings. Logically, you know all of that but it has surprised me at just what a difference it has made. It really is incredible. I tend to use it without the Contour switch-on. So thank you. It really is a great product.

My Shure IEMs are in my ears, connected to my Voyager, connected to my iPod. Handel's Messiah. Pure Joy. Nuf said.

The pocket sized Voyager portable headphone amplifier makes music on the move a whole new experience — capable of projecting an airy musical outside-your-head performance using good headphones, and with a source that's capable of it.

Use it with your iPod, Walkman, MP3 player or any other mobile device having an analogue output - line out or even its headphone socket - and hear the improvement.

The Voyager portable headphone amplifier can even make cheap headphones sound good: its contour switch compensates for the limited tonal range of lightweight street-wear headphones making them sound like real hi-fi headphones. From the moment of your first listen you will never want to travel without it.

Under the hood

Running on a single 9 volt "E-cell", the Voyager portable headphone amplifier drives high impedance headphones as easily as low impedance ones. It has a long battery life: usually lasting a month of average usage at good volume levels - and on occasion 3 months! This is because it uses a low loss battery polarity-protection system leaving more power for your music. When at home or at work it can borrow power from your computer USB port* or be powered from its mains adapter (supplied). Laptop users on the move can also make use of the USB* power facility, thus preserving battery power. Rechargeable 9 volt batteries charged on a separate charger may also be used.

The Voyager portable headphone amplifier uses noiseless DC to DC conversion to increase the 5 volt USB voltage to 9 volts ensuring no loss of level when powered from USB.

Stereo input and headphone output are on high quality Jalco 3.5mm jacks. The volume control is a high quality all metal Alps miniature "velvet" potentiometer of similar construction to the Alps AC27/30 often found on really expensive amplifiers, but a whole lot smaller. Switches are also by Alps - known for their precision. A clear low noise red LED warns you when the Voyager is switched on, helping you to conserve battery power.

The "no-bling" Voyager portable headphone amplifier case is made of hard-wearing precision machined textured ABS, featuring a black and silver anodised aluminium fascia plate carrying the necessary functional markings. A clip on cover securely holds the battery within its durable foam lining.

Each Voyager portable headphone amplifier is individually hand built in Britain by time served engineers and fully specification tested to ensure perfect operation. The circuit uses conventional through-hole non-surface mount components to help achieve its excellent and airy sound quality making it unique amongst miniature headphone amplifiers.

The Voyager is iMod compatible - it does not require DC blocking capacitors for a 3.3V powered iDevice - just connect and enjoy!
