These are probably the best cans in the WORLD for under £20. They are balanced, have great bass response, strong mids and sparkling highs. Although a little on the bright side for some, they do offer superb sound reproduction at this price. They are also sealed, and have a low impedance (32ohm), making them ideal for portable use. (rember to break them in)
Pros:
>Loud (32ohm) and sealed shutting out outside sound and sealing your music in.
>They are VERY light AND comfortable
>Unrivalled sound quality at this price point
>If you are one of the anti-Grado fashion-esque folk then these headphones are stunners, the look COOL and expensive.
Cons:
> The cable doesnt have an uptake and is quite long, so youll need a hairband or elastic band to keep the 3m cable under control.
>For the lazy hermits among you, there is no volume control, though i dont really see this as a disadvantage (they damage sound quality)
>They will make you/your teenager yearn for better sounding phones and when your kid starts begging you for the Senn HD650s dont complain.
