Just got mine, from western120, and am loving them already. Mine are paired up with the Sony NWZ-A829, and it's a great match. Smooth detail, big soundstage, with no hint of harshness. I was just reading up on the newest thread comparing these to the Shure 530's, and someone was saying how these TF10's have such harshness and sibilance that he/she couldn't stand to listen to them for more than a few minutes. I sitting here thinking 'are we using the same earphones?'. Because to me they're so very detailed without being harsh. I suppose they match up well with my ears though, and I get a good seal easily. I've also already done the flip, which lets the earphone body stay more flush with your ear and not stick out so far. I'm using Sony EX tips, and that helps some too I'm sure. So far though, I'm very satisfied. Definitely keepers.
