I ordered a second pair of ZS5s from Gearbest on 14th September and they just arrived today: Grey, no mike, definitely version two. I can't get them to show up in pictures but I can see two narrow strips, for want of a better word, in the nozzle, whereas I can only see one with my original blue ones. They're nothing like treble cannons to me and I would say they reolve a bit better than the originals. It's not a huge difference but it is noticeable (unless my brain is playing tricks on me of course). Listening to Back in Black, the cymbals are crisper and the snare drum has more impact. Seem to have plenty of bass too, whereas with the originals I kept taping off the vents to get more bass (then taking off the tape because I hate driver flex, then putting it back on again because I felt the bass was lacking).
I also got the ES3s and ZSEs. Not sure what I think of the ES3s yet although they sound fine. Unfortunately the right side of the ZSE is defective - almost no sound coming out - so I've requested a replacement. Does anybody know if Gearbest will insist I send the defective pair back and if so, will they refund the shipping?
