Hi! I am using Etymotic ER6i, but it's left side is dying, so I am thinking getting a new one. The price range would be around $300. At first, I was considering Etymotic ER4 series, but I am afraid that it wouldn't last long becuase it has such a long but thin cord that tangles up everytime like ER6i. So I have looked up on eBay, and found Shure 530SE PTH at $279.99, Westone 3 at $275 (it is used). I also am considering BOSE CQ3 because a lot of people have told me that headphones has a way better sound quality than the earphones. To sum up, my question is, which of the following should I buy for my Ipod Touch 1st gen? 1) Shure 530E PTH $279.99 2) Westone 3 (used) $ $275 3) Etymotic SE4 around $200 4)Bose CQ3 (used) around $200 Thanks in advance!!
