Gees, well I live dangerously, I've got an HE4XX which I imported from them (USA) to UK!I've shied away from Drop so many times, had stuff in the cart and then found a great reason(s) not to buy from Drop.
The number one reason is there is only a 30 day or 3 month return/warranty period vs years of warranty support if you buy the product in it's "real" form from normal channels. That reason has stopped me most.
The 2nd most likely reason is there isn't enough of a price savings to make me ignore the number one reason.
Probably the Zeroth reason is that buying on Drop is like ordering online in a Pandemic - without the Pandemic - you never know how long it is going to take them to ship it, or when you will get it. While I've watched for signs of a product to announce when it is going to ship I see a sale on the "real" item, and I order that instead. Or, I lose interest in the product because something newer / better is now available for the same or less cost.
Case in point, Drop has been having supply issues with (everything?) the HD6xx and people are waiting even longer than usual - double Pandemic mode strikes:

The last straw for me, and why I am peeved at Drop, was looking forward to the release of the ifi Zen CAN / DAC pairing at 2x the price I expected, and then went on to charge $85(?) for the 4mm interconnect cable. I had those in my cart for a while and then when they doubled the price I wrote them a complaint and until today haven't been back there
I see Drop added a 3-year warranty option to the HD6XX for $30... where does Drop plan on getting the spare HD6XX's or parts for repair to service that warranty, they can't even keep stock for sales!:
Add Drop 3-year Warranty with Accidental Coverage (US Only) +$30

The HD6XX is nearly half price from them though in comparison to buying HD650 in Canada by the looks of it, so I think the large cost saving offsets the risk of shorter warranty and all the hassle associated with buying it from another country....I'd just risk it for that good deal. The waiting for the product to ship would probably be more of a pain in the ass for me than the other negative points.
