are B&O hedphones good?

I've not listened to these particular models, but in the past I found B&O to be tinny and sibilant.

AKG at that price point is a much better deal.

@erik_squires thanks man. Im checking them out now. would you recommend a certain model?

Googling shows that these particular headphones were made about 37 years ago.  Not sure if that's what you really want to spend $125 on unless you want them for vintage/memory purposes.

I have visited and listened to B&O stuff and it has never impressed me.  Their products are more for people who want that gadget type look instead of people who want a good sounding system.

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

@erik_squires  I’m thinking on those, thanks.

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.
