are B&O hedphones good?


I am looking at a pair of B&O U70 headphones on Craigslist; are B&O headphones good? if so, should I pull the trigger? Price is $125

For AKG, the 240s are actual studio references.  The 700 series are pricey but excellent.

You should also check out what Hifiman has in your price range.
FYI, I just recently got some AKG K712.  It is excellent in resolution.  The K240 is likely very good as well, but it has a bump in the 100hz midbass area and a pretty high peak at the 6-7khz area.  This would make the midrange a little hidden, but the resolution is likely very good.
Ah, added note.  The AKG K240 mk ii model for $128 is a LOT flatter in frequency response and better than the $60 version.
