I also got my CIEMs from Rob today, triplefi.10s, and they are amazing! Fit comfortably, sound as great as they always have, but with better seal. I couldn't believe it could be done for less than I paid for them new, and with all of the options, but it's true!
For those with doubts, Rob has gotten much better on the communication on the IEC Facebook page, and I had no issue with the timing since I always have a pair of headphones when one goes down. Remember, you can only pick two of cheap, fast, and good, but he picked the right two! He even sent my impressions back so I can use them for a future set if I want.
First post...seems a little fishy, plus sending back impressions is common practice
