How does it compare to the Haylou GT1 Plus in terms of SQ?
Hmm. so far i feel like it's like a more fun sounding version of the GT1 Plus? There is noticeably more sub-bass, and treble seems a tiny bit more extended (or maybe similar). Both sounds good in the mids, but because the Gt1 Plus has less sub-bass the mids sounds a bit more forward in some tracks? But if i'm listening to like a track without bass like this guitar track "Depapepe - Ii-hi Dattane", it sounds about the same. Maybe the Z1 has slightly better separation too? But it's like really slight. Both are smooth and enjoyable to listen to though. But Z1 probably gets my vote because it's able to get a lot louder. I have like a few songs i listen to that are softer and sometimes when I'm jogging the Gt1 Plus is still a little lacking in volume even when i max it out. Having a bit more headroom is nice.
