Westone's 4 R-Series quad-driver IEMs pack Acoustic Symmetry, cost $500

Remember those impressiveWestone 4 in-ear monitors that came out late last year, priced at a whopping $450? Well, the company's ready to best itself again -- and have audiophiles open their wallets a bit wider -- with its new 4 R-Series. This latest set is relatively similar to the 4, still packing Westone's EPIC cable (now detachable) and four balanced armature drivers, but will set you back an extra fifty bucks in the name of Acoustic Symmetry. Westone claims the 'phones achieve an "extremely tight tolerance of +/- 2dB between earpieces," meaning your sound should be extra consistent from both buds. The 4 R-Series buds are expected to arrive before the year's out, so in the meantime we'll just direct you to the PR past the break.
