bryantHi Bryant,
The IEM's we sourced are from an official channel with full warranty coverage, just the same for all the products available on Massdrop. We stand behind our products 100%, if you have any problem with the IEM's within the warranty period, just shoot us an email; we will be more than happy to take care of repair/replacement for you.
Do we get proof of sale from the vendor, and is the vendor authorized per any of these pages? http://www.shure.com/americas/where-to-buy/in-store http://www.shure.eu/meta_eu/where_to_buy http://www.shureasia.com/en/meta_en/where_to_buy
If both of these conditions are not met, the warranty is invalid.
