First impressions:
I think I've got a used or at least opened ZS3. The package had no foil around it, scratches on the inner plastic, also the cable was formed to the wrong direction on the right site (Like someone had tried to plug it in in the opposite direction and then fitted it to their ears) and the package with the tips seemed to be either poorly sealed or opened once. Maybe because of the wrongly inserted cable they were sent back, the right side sounded faulty at first until I rearranged the cable. (I didn't knew how the cable should be connected so I took the form of the earhooks as a clue)
Nontheless they sound awesome
For me this is the next Jackpot after the ED3. Beside a tiny bit of too much bass this is the sound signature I'm looking for right now.
Well, one man's loss is another one's gain.
The ATR actually sounds pretty alike. A bit artificial in direct comparison. Not bad though, but I'll prefer the ZS3.
I've had the Urbanfun to listen to music for the last few days and what I missed where those exciting highs. They are still good headphones and have their treble but it sounds dull. Maybe that's what many refer to as "sparkling highs", something I really crave right now.
Now I really wonder how the ZST will perform.
Edit: There's a sticker on it "QC 76" so it might really be tested and therefor opened?
