Early March 2020, Drop sold these for USD 199. The drop on March 24, 2020 was USD 250; just like the drop today (April 16, 2020). Why the price increase?
In the past the price would get lower after a certain number of buyers had bought the product of that particular drop. This no longer seem to be the case. At least not with the last few drops of the Etymotic ER4SR/XR.
