Are the ATH-m50X any good? Speaker went out on my SOL Republic Master Tracks, and was going to return them for those. Also have the Pro700MK2 coming today in the mail. It's at my local post office now
The M50x are not remotely basshead headphones. Also, the Pro700Mk2 are pretty veiled. If you don't love their sound and can return them, the WS99 is a much more sparkly V-shaped sound with roughly the same bass potential and fit (but doesn't clamp hard like the Pro700Mk2).
