first off, i have PC37X and they are great, lasted forever , bought the 38s thinking i would upgrade but the right ear makes a vibration " crackling sound to where these are unusable. I never dropped them and have only had it for 3 months where it was treated well. Maybe just unlucky and bad soldering.
Garrett450I believe I have the same issue with my headset. When I talk or move my head around the right ear has cracking noises. This seems to be from poor build quality, nothing to do with the electronics or drivers but the plastic parts in the headband.
Garrett450No reason why the headphones shouldn't work years to come. Please contact our support team so they can look into this. Your headphones have warranty.
Garrett450I bought the PC38x too (on amazon via Drop's store directly, not here) and had the exact same issue as well. DROP also refused to cover them under warranty when it's clearly an issue with the headset.
Later they came out saying they won't offer support because it's a third party sale (through Amazon, but literally from their own Amazon store), this isn't listed anywhere on their product pages.
They're walking a shady legal area with this stuff.
