Sansa Clip – very good quality sound (if you don’t use the equaliser) but not too much grunt from the amp (which is why you can’t use the EQ).
These cheap Koss give a surprisingly good and very listenable sound:
a quote from an amazon review:
“The sound is really really good. Absolutely unbelievable for the price”
and for £12.39.
I have the Sennheiser PX100s and they might be a little more accurate than the Koss’s, but the Koss’s are much more enjoyable (think tube amp versus solid state as they have a slight bloom in the bass).
The Koss Sportapros sound very similair, or the same, but they have an over the head OR round the back of the head band, for a couple of quid more:
DONT be tempted by the Koss Portapros, even thought the reviews are good:
they are WAY too bassy, completely mess up pianos, etc.
