If I remember correctly they are the same earphones... The "c" stands for consumer and is sold in the consumer market while the other is sold in the professional market. Generally the prices are market down lower in the professional market, so I assume that is the reason for the 128.00 marking. If this was a brand new purchase, I would contact Shure.
Etymotic earphones used to sell in the professional market for a 10.00 lower price tag but had to change the name of the phones... Musians Friend used to sell them as such while Audio Advisor had the regular consumer name and mark-up.
Your iPod should drive them fine.
