By far the most unusual item coming out of this Sony announcement--and possibly the most unique audio gadget we've seen in years--are the PFR-V1 Personal Field Speakers. This crossover home/portable unit offers the rich, open sound of speakers in the design of a headphone. The speakers actually rest in front of the ear while the loops--called bass reflex ducts--coming off of them are inserted into the ear for maximum low-end. There's a lot of sound leakage, so these "headphones" aren't ideal for on-the-go use. They feature a 21mm driver unit and operate off of 2AA batteries for up to 200 hours. It's definitely a premium unit with pricing at $500.
