I am in the market for a new pair of IEMs. I listen mostly to Jazz (Apple lossless files) and will be using an iPhone 3GS as a source (and amp?). I have never owned IEMs, but I guess I am more on the analytical side (and if some coloration is necessary, I would opt for the warm+sweet) and plan on using them while commuting. After reading many reviews, I have come up with some candidates: i) the Vsonic GR07 mkII ii) the HifiMan RE-252 iii) the Brainwavz B2 In addition to these offerings, I am considering some less expensive solutions, such as the HifiMan RE0 and REZero, the Vsonics GR06, in which case I could add a portable amplifier and some more expensive ones, including the Sennheiser IE80 which can be had for ~€200 at amazon.de. So, which way should I go? And if I go for the Vsonics, any trustworthy ebay reseller? Many thanks!
