Owner for a couple years now. Very happy with them for the price.
For the time I've had them so far, they keep surprising me with something - even lower extension of bass, more detail (when I switched sources).
What I'm glad they haven't surprised me with so far is any physical problems with them. Pretty rigid these little things. Been using them with tips supplied with a-Jays, which they left me with after RMA, as the stock tips aren't really good. Will see how much longer they will hold up for before I have to replace them. Will most likely have to invest more money when that happens, as I can't stress enough how good of a deal these were for how much I used them with appreciation and comfort.
