So I'm a long, LONG time audiophile and speaker and sound system 'connoisseur', of sorts. I've owned them all - Klipsch Reference series, Polk Audio high end subwoofers, M-Adudio, KRK studio monitors driven by a NAD C325BEE amplifier, Bang & Olufsen BeoPlay S8's (still have these, they're not going anywhere) - and Bose Lifestyle systems. Just bought a pair of Beat Pro's - HOLY **** - Are you KIDDING ME? These things sound incredible! - they simply sound, well, unreal. Everything from the incredibly detailed and musical bass response, to the mids and highs, everything just sparkles and shakes my spine at the same time. I've never heard a pair of headphones sound this good. Or audio in general sound this visceral and surreal. Granted I'm sure a pair of Sennheiser HD800's would smoke these, but for 1/4th the price, I'm beyond a Beats Audio fan. These are the post-split Monster vs. Dre Beats Pro's - the Apple-owned versions sans Monster. Additionally - I will say these absolutely ECLIPSE the Studio's - even the new wireless 3's w/ the Apple W1 chip - Just bought those a few days ago and it's a night and day difference - I'll be returning those. Love. These. The new Beats Pill + I bought for my Mother for wireless streaming from her new iPhone - Unreal. Sounds as good mid and treble range wise as much bigger, higher end bookshelfs. Bass is incredible for its size. Granted, if I heard the original studios I might have been a Beats hater, too - but these newer Apple Pro's are just simply sublime.
