!!Planned for release in Spring 2014!!
Skip to 7:26 for the news.
UPDATES: Oct 11 2013:
Regarding whether they are planar or not:
When visiting the Fostex booth, I only asked about the prototype RP headphone. It is open back, has a slightly modified T50RP driver, uses similar housing and headband to the TH600/900 with different pads (smaller opening for the ear) and a perforated metal open back. The prototype was displayed as a physical sample: While I was offered a listen they said it would not be anywhere near production voicing. Release planned for Q2/2014.
UPDATE Oct 27 2014:
Confirmed on multiple sources that the "RP50" will share the same drivers as the T50RP?
From Innerfidelity website:
Fostex RP50 Prototype...and TE05!
'' In my mind, this may be one of the most interesting stories of the show. You see, the RP50 prototype uses the same planar-magnetic driver found in the Fostex T50RP headphone that headphone DIYers love to modify. It is a really competent driver when placed in a well-designed enclosure, and I think Fostex has something very special in this driver alone. The show was too loud and commenting on prototypes under the circumstances would be silly, but I know these drivers can sound very good. I hope Fostex finds ways to use use them in a lot of products...even products made by others. Mr.Speakers uses them in his Alpha Dogs, which really are a spectacular headphone. The point is: The story of what Fostex does with its killer planar-magnetic driver might be very, very interesting...in lots of ways...''
