Lostdog54Mine is shipped, but .1lbs.
I don't know about UPS/DHL tracking details, but FedEx posts the package size. From the looks of mine, 6x4x1 inches, and its weight of .1 lbs, I didn't get lucky.
dahn626Interesting post from the last Sennheiser grab bag drop further down on the thread.
You can have a good idea of what you got by the shipping weight when you receive the email confirming their shipping. From what I found CX 1: 0.1 - 0.12 Lbs CX 2: 0.15 -0.18 lbs CX 5: 0.25 - 0.37 lbs
Merely speculation on my part and assuming theres no additional packaging from Massdrop that would skew this estimation.
