i've had a pair since september. its pretty mid centric and vocals sounded great on them.
the biggest flaw i have with them are their design. the flat cables make microphonics totally unbearable. hence, when on the go i'm forced to wear it over ear, but u have to switch channels to do that. and for my pair, one side of the "tdk" logo plate fell off from the housing, den the cable coming out from the strain relief of the extension cable towards the mp3 player spoiled (distorted sound, need to adjust adjust to get a good sound, = basically unusable becos without the extension cable the cable is tooooo damn short), which probably was my fault since i abuse my earphones alot lol. after that i simply jumped on a vsonic gr07, n nv looked back. still lazy to get them rma-ed, which i will do soon b4 considering selling them.
but at the price i bought it for (SGD $100), they are totally worth it.
