Hello Head-Fi. This will be my first time posting here. I'm sort of new to choosing proper headphones (as in, before I always just bought $20 dollar things at the drugstore), but I've narrowed down my choices a little bit. I'd prefer to keep the prices less than $75 if possible, but I can be a little flexible if need be.First of all, I was looking at the Soundmagic PL50 ($65 on Head-Direct). I also checked out the MEElectronics M6, but I've heard complaints that vocals are somewhat tinny and the highs aren't too great. I listen to a wide selection of genres, so I don't really feel good buying something that seems to be geared more towards one or two specific ones. As well as these, I also looked at the Apple Stereo earbuds, since they only cost $1.59 and I could order 40 pairs for the same price as the PL50s... just kidding . The main source I'll be using them from is an iPod Touch, 2nd gen, currently without any amp. Also, the Multi-IEM Review says that the preferred tip for the PL50s are the "Sony Hybrids"... any idea where I could get these? (I live in Canada). Would you guys suggest any other IEMs in this price range to someone who's new to them? On a somewhat related note, is there any real advantage (sound quality-wise) to wearing them with the cable over your ear as opposed to straight-down? I personally find over-ear to be somewhat uncomfortable. Thanks in advance!
