Well, I purchased the SE215s last week, and I'm still not sure if I like them. Luckily I ordered them from Amazon, so they may go back. I may order the MA750 before I do that though so I can decide between the two.
Still interested in the TE-05, but Amazon has them priced much higher ($192 CAD from a 3rd party) than the Shure ($125 CAD) and RHA ($125 CAD). However, Headphone Bar has the Fostex on sale for $130 CAD, but it's final sale.
I rather not take a $130 gamble on the TE-05. So any input would be greatly appreciated.
Se215 is kinda of like a neutral iem with not much bass compared to Fostex. If you want something you can use in commuting, I would recommand se215 or the ma750. As isolation on the fostex is pretty poor. If you are considering replacing cables in future fostex may not be a better choice as the cable from shure does fit the fostex. But there is no locking mechanism. Which makes it pretty loose if you move a lot, having risk of losing one of the earbud. Btw, both have the same mmcx connector. While the rha have no replaceable cable, but it comes with 3 years warranty. Depend on the genre you listen to though. I have not audition Rha ma750 before, so I can't give comment about it.
