Avegant released a headphone with a virtual retinal display called Glyph. They have a kickstarter campaign going as well. Looks pretty cool. The heads up display flips down like a blast shield from the headphone band. Should be very interesting to follow.
Harman unveiled a new one that looks pretty interesting - JBL Synchros S400BT. Been looking for a set of BT headphones, so I may wait for these. Uses apt-X and looks pretty durable. Will wait to see how good it sounds though to see if it ranks up with Sony's MDR line.
Yes, I saw Audio Technica released nine new headphones, while Sennheiser and HiFi Man released new ones too. I also saw an article that said Monster had a huge display and brought in Shaq as a guest, but would not let anyone phontograph must of their new gear. I was also very interested in the new Beyerdynamic A 200, which looks promising and I am hopeful some headfiers will get a chance to post comments on what they hear.
