What's the impedance for this headphones cause i got HEAVILY confused.
on their site at the top of the pdf (which is the technical data of the headphones) it says 50 ohms....at the botton it says 120 ohms

What???
can someone solve this problem?

50. Check the data sheet here if you want: http://www.sennheiser.co.uk/uk/icm.nsf/resources/HD_555_GB_new.pdf/$File/HD_555_GB_new.pdf

yeah, that was i was talking about....but look at the botton? what does in those squares write?

120 ohms...so???

and i also read on severl sites it has 120 :
i'm really confused

and another question...does a 120 ohms headphone work fine with the pc? with an integrated sound carD?

if you will buy an hd515/555/595 brand new, it will most likely have a 50 ohm impedance.

and if i buy them second hand they will have 120 or what?

anybody solved this mistery?

there is already a thread on this as I stated there the new ones are 50ohms and the old ones are 120ohms. most likely if you buy some new you will get 50ohms if you buy them used just ask if there 120ohms or 50ohms pretty simple.

ohh...i got it now...thanks

very important info. THANKS!!!
i think i'm gonna buy a new pair of hd555's
and if we are still talking about impedances....i hope someone will answer this question

what's the maximum impedance so that a pair of headphones can work fine without an AMP....does the old 120ohm version work without an amp?
