arrived, waiting for seller to let me know which store to select when registering for warranty. the serial number checks out though

came with 100% battery and 4.1.1 firmware
just updated to 4.2.2, the noise cancelling is really gaolat

where you bought yours from. 299 good price liao. i bought from qoo10 and paid 339. I tried a xm3 with 2.0.0 firmware in bangkok, the anc is way way way better than 4.1.1 and 4.2.2. Thats actually the reason why i decided to buy.
looking at the forum, i think im the very few exceptionally suay kia to get a faulty model. Pay $300+ better check to make sure everything is flawless, so you may considering doing this to test for faults;
1) off music and on anc, then walk around and shake your headabit, check for clicking sound.
2) go to a quiet place, off music and on anc. observe for hissing/static nose. can also feel abit of weird pressure. Hard to notice when music is on.
Really like the sound of sony xm3, but those small faults really irritates the f out of me.
