This is a deal for all you folks who took up the Shure SE110 £24.99 offer.
I bought this little amp a couple of months back after reading about it online. I'm still amazed at the volume boost and bass improvement it gives when listening through my Shure E2C's.
It's available in white or black and comes with a 3.5mm interconnect to hook it up to your mp3 player of choice. It takes 1 AAA battery and is pretty small. Not much bigger than the battery itself.
Audiophiles may scoff and dismiss it as 'cheap chinese junk' but for £4.62 ($8.50) delivered, I seriously doubt you'll get more bang for your buck. Have a shifty at some of the forum comments and reviews about it online. It's building a bit of a cult following.

I've linked to the white model on DealExtreme, a quick search for 'fiio' will show the black one too, which is the same price.
