I am looking for an unobtrusive IEM that i will forget that I am wearing.. budget.. around $100
Etymotic phones with the cone-looking buds seem to be ideal but I cannot judge from just seeing the pics.
Please advise !
Phonak is extremely comfortable, and it's really a pity that they are dropping out. I'm not much of a fan, but the Klipsch X10 is extremely comfortable (as it is very slim and really disappears in your ear) while having a very good level of isolation as well with a deep insertion, a combination quite rare among IEMs. It sounds quite decent too, and can be had around $100.
I think this whole time you've been meaning "physically unobtrusive", not "unobtrusive sound signature", right?
If so, the answer is Etymotic ER6i with some regular hybrid-style silicone tips (because I know if I didn't mention that last part, someone would freak out about the recommended deep-insertion -- it's not really necessary). ER6i are absolutely tiny.
