If my plane ear doesn't get better, I may have to put my headphone-ish on hold for the foreseeable future. May have to contact Creative and tell them I can't review the JAM. It's been 3 days, and I'm practically deaf on my left ear.
If you don't have medical insurance, word of advice: don't get sick and then get on a plane. The congestion + air pressure change can totally ruin your ears. Learning this the hard way.
I've cursed my existence years ago, so this is just smearing more **** on the already pile of **** I have to deal with.
Good news for you guys, this means I may just offload all my audio stuff, particularly my basically fresh out of the box replacement X2. Bad news being that no way I'll continue the headphone game if/when I find out I'm screwed on my left ear forever..
