OK. My son is looking for some IEMs at under $100... less than $50 would be a bonus. Must have good bass, but I am trying to steer him away from boomy bass crap. From what he has read so far, he seems to be interested in the Ety ER-6is, or the HF-5s. I also want him to look at Shures if he can find something decent in his price range. Also the Headdirect ER-0s might not be too bad, but also might not suit his preferences. He keeps reading crap on the 'net that is all over the map on recommendations. I have really no experience with IEMs, so any recommendations? I know this is way below the $$ threshold most of you look at so...
