will sennheiser hd280 work well in ipod classic

[fireworks1]

i just found out about how impedance works and now i'm kinda worried if i won't be able to hear my music because the impedance of HD280 is kinda of high compare to other headphones (64)
 
also, i'm getting ipod classic 5gen. 30gb

It's impedance is not that high.  You'll be fine thanks to its sensitivity.
