I can't speak for Bluetooth specifically but I'll definitely echo what others are saying. Beats are all marketing and you're paying for the cache of the name. I've demoed them rather extensively and always come away disappointed because of the price. For that money there are some seriously good headphones out there.
If they were, say, $50 instead of $250 then they might be worth recommending.
As for Bluetooth, I haven't heard a Bluetooth stereo headset yet that sounded better than a $10 pair of earbuds…
