You will NOT get more bang for your buck than these. I'd have been happy had they cost me twice the asking price here. They out-perform my £60 Senheissers easily.

Unfortunately I lost them, so using some Xmas cash I bought the top model in the range. They cost twice as much, but are about 5 times as good!!!! With the right EQ settings on PowerAmp (the best player IMO) these things are simply outstanding.

Both also have the best cable I've ever encountered. Almost impossible to tangle. Just take them out your pocket, give them a shake, and they just unravel. No messing. Very very well made too. The box they come in could be used as a time capsule. The most over-packaged product I've ever bought!
You wont be disappointed with either of these.
P.S. If anyone buys these, please time how long it takes you to get the packaging open and post your results back here!
Edit: Found the a-Jay Threes £10 cheaper here...
