My phone was purchased on November 2nd, request submitted a few days after that, and earbuds arrived yesterday, December 3rd.
Jury's out for me on them, however. They fit like a dream (WOW they're comfortable), but even though I listen predominantly to classical music and speech, there's too much treble and not enough mid-tones for my taste. It also sounds like they're adding reverb (unless that's a case of them providing added clarity which lets me hear reverb in the mix....)
I actually only got them because they were a good freebie deal, and I'm not that bothered since I don't listen using buds all that often. I'll try them a few more times, but if they don't work out for me I plan to give them to my daughter - she uses earbuds WAY more than I do, and will like having a pair of higher-end ones than the cheapies that she usually uses.
