Sonically the best, but the cable is a disaster!

Sonically the best comes with the Sennheiser, AKG headphones to the 300-400 euro with absolutely!
But only after I the foam tips (5-set to the 20, - Euro) have changed, for me has only thus give a good fit in the ear. Clear, pleasant sound without annoyances, very well also in the bass range.

Technically processing my listeners was a nut: the left earpiece broke up after a year in 2 halves. UHU all-purpose adhesive has helped here.

Crackling and 'Sound Off' now on the left channel - after 2 years, but only rarely use.
I have the cable carefully cut - and lo and behold: the 6-cm-long wire to the listeners for round-the-ears-turn had destroyed the insulation around the two leads. How ever this isolation already crumbling from easy look.

For an investment of around 300 euros little consideration!
