A very nice review, thanks. I completely disagree though - to me, these things are bloated with mid-overshadowing bass and tinny with too much treble. I dont care what they cost - value means nothing if it doesnt make music sound enjoyable or even tolerable. And £30 for some headphones that I couldn't tolerate for more than 10 minutes is too much.
Dont reply with an argument for burn in, either - that's fallacy. Put them in your ears and press play. What you hear is how they sound.
I guess if you have something worse than these things and thirty quid going spare, buying them might be a good investment. But otherwise, leave aside and spend more for more would be my advice.
