Great little box!
I ordered this product because I just bought a pair of studio headphones that needs just that bit more power. This little device has its own internal batteries that are re-charged using an AC/AC transformer that you need to purchase separately (note - DON'T use your average AC/DC adaptor!). It comes already charged and you simply plug in your source, plug in your headphones and off you go. Fabulously clear sound and gives me the boost I need to drive my cans. Oh, and there's a little button that boosts the gain if your source track/device outputs a particularly low signal. Lots of people say it's too big to be used as a portable device, but given the size of today's mobiles, I disagree!

Perfect for powering DT 770 250 ohms
Perfect, loads of power and clear as crystal. No signature sound to this amp just pure sound that is always true to the source. Seller included a PSU and was very helpful. If your after an amp that has no noise, adds no extra character and can power 250 ohm headphones with ease, this is it.

Great little amp from a clever and honest designer
Cheap, no frills and very effective unit, clear and quiet amp, capable of driving the most current/voltage hungry headphones (planar magnetic/high impedance)
