So my ZS6 arrived from Gearbest the other day...
As you can see they are rather beautiful.
I decided (for now) not to cut out 1 BA from each.. but Instead I thought I'd first try to burn-in the BAs with insanely loud high-frequancy white-noise.
Here's a shot of foobar that I took of the burn in (note the EQ and volume??)
It was so loud that I had to wrap them in foam and I could still hear them 4 feet away.
You wouldn't believe the power those BAs can handle...
I did this for several hours then did a standard burn for more hours at full range.
This did nothing to calm the sibilance, it almost seemed worse after the burn-in.
So, I decided rather then rip out a BA like I did to my ZS5v2, I would just take a very small amount of bees wax and plug one BA from each earphone..
This worked quite well for muting the BAs without having to remove them..
I
may even be able to undo it by pointing the earpiece BA nozzle downward, and then quickly heating the BA with a very low watt soldering-iron, then absorb the beeswax with a Q-Tip.
Although I don't ever see myself doing this, unless I start going deaf in the 10Khz region.
Early impressions:
The highs are tamed rather well now, and they sound good even on highly sibilant tracks (like every single song Animals As Leaders ever recorded).
The bass is definitely more intense then my ZS5v2 (modded with 1 BA removal & micro pore tape over the ear facing vents).
I can almost feel the bass punching me in the chest!
At times the lower midbass (100Hz to 160Hz) is slightly louder then I like but, it's nothing I'd be too bothered by really...
If I had one wish; I would like to add a bit of the mid-treble clarity of the KZ-ZST..
I wouldn't mind a wider soundstage (again like the ZST), as well..
I think I still have a bit of a crush on the ZST, even though it's mid treble is just evil at times, there's something about the ZST's sound stage & clarity that I just love.
Also, even though I tamed the sibilance by wax-muting a BA in each earpiece, I still feel like the highs are slightly on the artificial side of things..
It's rather slight now, but it could definitely be improved.
It would be nice if I could hear more of an -even- range in the treble, like a flat response between 4Khz to 16Khz would be nice.
Oh, and one last important thing:
For some reason the ZS6 doesn't hurt my ears.. I can only take the ZS5 for 1-1/2 hours maybe 2, but the ZS
6 is surprisingly comfortable...
