While this headphone is very good, I've come to find some things quite annoying about it.
Bass is clean and tight for the most part but certain frequencies are lacking clarity, it has a messy texture/poor detail. In general the lower half of the mids have a haziness/fuziness and lack resolution. Its a bit messy. In particular when theres alot of overlapping instruments, especially multiple electric rock /metal guitar.
I've found that some people are offended by mods so just a spoiler alert, mods ahead.
First thing I like to do when modding, is to swap out the driver wire. In my experience alot of the headphones use really cheap internal wiring. The highest quality wire I've seen in headphones thus far is in the Focals, the elex and clear both use 24awg silver plated copper wiring. The 7200 use what looks like 28awg stranded copper wires.
My choice of driver wire is mundorf silver gold solid core wire, it enhances everything to a whole new level. In my Focal Clear I used 18awg because the stock was 24awg, in the 7200s I used 24awg because the pcb looked too small to accomodate an 18awg wire.
After listening to it for a few days, I found that this mod did not help much with the clarity issues in the lower half of the FR.
I listened to the driver while it was out of of the housing and felt around for areas that were vibrating excessively. The plastic housing holding the driver in place is quite thin and cheap and I could feel alot of vibration coming through it. I placed some fo.q tape to dampen it. 4 spots around the driver housing and some tape under the 3.5mm jack. The pcb holding the 3.5mm jack is floating and looked prone to alot of vibration so I placed the tape underneath it. It fit snugly and firmly supports the jack.
The negative aspect to this part is that there is a small loss in bass volume, about 5% if I had to quantify it as a number.
The tape cleaned up alot of the messiness but there still seems to be a little bit left. I will listen to it for a week or so and reevaluate more tape around the driver since that area seems to be the cause of the issue.
