I would not stay on the qualities of the helmet, my rating says it all (for me it lacks some bass and volume though). I want to report this comment to see the AE2 and AE2i are exactly identical. The only difference is delivered cord. -on the AE2 cord is standard and works on any device (including iPad) -on the AE2i condorn is SPECIFIC ipod and company, and will only work on these devices. So if you do not have an ipod, this cord will be useless.
Both cables are sold separately on Amazon. That of AE2 is 8.19 That of AE2i is 29.95
