Simply put, if you're looking for some earphones at around the £10 mark, look no further. Why do I say this? Well, most earphones in this price range tend to be incredibly V shaped, with an incredibly bloated bass and a shrill, muffled treble. These on the other hand, have a far smoother and deeper bass, nice mids and a controlled treble. Don't expect these to compete with anything in the £30+ bracket, but these do wipe the floor with any Skullcandys, or the ever present CX300 and EP630.
So, in conclusion, if you're looking for an upgrade from your standard iPod headphones, or are just looking for a quality, rugged pair of earphones to take with you wherever you go, these are the ones for you.
