The 40 pin connector[1] has pins for headset left, right, mic and detect, so 
it should support a headset connecting through this at least. There is also a 
minijack socket that appears to be 3.5mm[2], but the spec[3] and pin 
disposition suggest this may be audio out only. If so it's an odd choice as 
there is a de fatcto standard for 4-pole minijacks for headphone and headset.

USB is also on the 40-pin connector. Judging by the beagleboard, the OTG pins 
wil give gadget or OTG support while the other port will give host mode. There 
doesn't appear to be a 5V out pin though, so host mode may be unpowered.

Personally I would rather see a pair of usb ports than the micro-HDMI and the 
barrel power connector, and make sure the headset connector is 4-pole with mic
