Today only, until 3:50 pm ET (or 100% claimed), Amazon offers its Prime members the Bowers & Wilkins P5 Headphones in Black for $179 with free shipping. That's the lowest total price we could find by $121 and the best we've seen. (It's also an $11 drop from our April mention.) They feature sealed leather earpads, neodymium magnets, and Mylar diaphragms.
