Thanks for your support of HiFiMAN and for the question.
Product lead times can be long so HiFiMAN is always working on new product ideas.
HE-560 will be shipping soon with HE-400i right behind it. Nothing else to announce at the moment but stay tuned.

Any idea if u guys will ever go over to angled connectors (would help for people with short necks!) or mini xlr? (Ur connectors restrict the thickness of HIGH END headphone cables..mini xlr accepts 8wire cables at 18awg, as ur connectors maxes out at 4 wire at 18awg)
Thanks peter!
