Yep, some of the Egg Attack figures have a slightly 'Chibi' look to them, there is quite a fine line between Super Deformed and 'Cutesy'.. I'm not big on 'Chibi' miniatures, unless they have an old school, netsuke look.
Having enlarged some of the photos, it appears the 'cable' with the headphone jack maybe more of a cord, kinda like a keyring or camera cord which loops through a metal ring recessed into the figure.. in which case the cord may not even be attached when you get the figure in its retail packaging, which would make them great mini-figures for display.. hopefully someone can confirm this, once the figures are shipping.
