Beats are a joke, anyone who says otherwise clearly has no real audio taste. I tried a pair of the studio ones on in the store, and it was rather underwhelming.
The same could be said of Bose; I actually have the QC15's (gift), and I can honestly say I wouldn't spend my $300 on them, although they are decent. Mids are solid, bass is lackluster in comparison to some cans but still there (I think it cuts out around 35Hz as well), and highs are decent, but not fantastic. They're honestly better than I expected, and the noise cancellation is the best you're going to get without going IEM, but still, I wouldn't spend the money on them.
As per the purported "expert"... spam harder please.
If you're going to spend $300, at least get a decent pair of cans; Beyerdynamic, Sennheiser, etc.
