senn HD25-13 600ohm worth the extra $ over hd-25

[lanz]

I am sorta new to this
but is the extra $ money worth the 600ohm version of the hd25?

what does the ohms represent ?

short anwser: you don't want the 600 ohm 25-13's, you want the 70 ohm 25-1's

long anwser: the 600 figure is the impendance of the headphones. this means that these headphones need a lot more volts to get sound from them.

for you, they'll probably be worthless, unless you've got a beefy headphone amp that can supply the necessary voltage swing to drive these headphones. the 25-13 model is meant for studios, where a high impendance is necessary for connecting multiple headphones to a single amp.

the 25-1 is the 70 ohm version, which doesn't need many volts at all. these will run very easily from any mp3 player, or indeed any headphone output. as far as the sound quality goes, there might be differences but i've never seen any report of the 600 ohm version.

the best part of the 25-13 professional studio headphones is the cable, which when shortened and fit with a 3.5mm plug is great for the 'consumer' 25-1 version (which by default sports an inferior steel cable)

I just received a pair of the 25-13 (600 ohm) and also already own 25-1 (70 ohm). I agree with Firestarters' statements. My first order of business has been attempting to see if there are any significant differences in sound and do not see, at this time, such differences......although in terms of the higher resistance (ohms) actual performance is not as impaired as much as one might suspect. Yes they certainly require an amp, but my gain (Xin Supermini) will not likely have to be increased at all.
