I've been listening to these almost exclusively now since the 31st (though I have spent a few hours with my Mobius and 6XX to compare) and I finally found a setup that works for me.
I found that my ears are too big for the ear hooks unfortunately, and after 20-30 minutes they feel like they're pinching so much its unbearable. The small ear locks work great, coupled with the small foam tips they include. I picked up a TRN 8 core mmcx cable from Ali for a few bucks, and its so SO much better than the stock cable. The stock cable is so heavy it feels like it's pulling them out of my ears. Finally after some tweaking I found what to my ears is a very good EQ profile (pictured below.)
Once I made all of the changes here I find myself not taking these off all day, the sound is really great for the price, especially if they're on sale for sub $100. For sitting at my desk at work all day this is the only thing I'll be bringing from now on. Just want to say thanks to everyone in the thread for all the great info here, it was very helpful in getting things setup just right for me.
