Hi Postrock. Yes, the congestion thing was what mine seemed to have big time out of the box. In fact, I thought there was something wrong with them so I quickly changed to a Senn PX200 in order to check. To some extent, the track I was listening to was quite congested and compressed to be fair, but the Zoro seemed to make it worse. They nearly ended up in the bin!!!
About 20 minutes in (I suppose) I listened again and they seemed to have relaxed a bit. Now they've done 9 hours they sound fine. I've only ever had the same happen with a Superlux headphone before.
They have a richness in their sound that is really nice and yet listening to speech doesn't produce the boom that you can get with male voices.
After seeing that dip at 4KHz (Thanks to Tyll) I was very aware of it. Psychologically, I was ready to hear a dip and at first I wasn't sure whether I could hear it or whether my mind was playing tricks after seeing Tyll's graph. Orchestral seemed to highlight that one area though. Some kind of dip in the treble but as Dweaver says, some sibilance as well.
I find Tyll's reviews pretty much similar to what I hear and he did it again with his review of this one for me which is why I wanted to try one.
Also, in the UK we have that EU law on MP3 players where the volume is limited so a good headphone that's really sensitive at 16ohms is a real bonus. No need for an amp if we can get a good one that goes reasonably loud on a British player!! (or maybe I should go for the Amperior at 18 ohms)
I must admit though, I really do like the Zoro a lot. They are better than the FW's which in comparison sound quite 'boxy'. Twice the price here too.
I'll be including it in my roundup review which should be done soon. I'll post the link here. Thank you. I'll look forward to seeing it.
