I have not. Considered buying a Phonitor at one point but ended up making the mistake of getting a Decware mini-torii instead.
It turns out I sent my K702 65th back today. I wasn't thrilled with the sound at all, mostly because I think the new pads are a complete and utter miss from a sound quality perspective. To see what effect they have I swapped them onto my K701 and they made the headphone more bassy and warmer sounding but the bass is really fuzzy and they wipe out detail while moving the soundstage closer and narrowing it leading to what I found to be a highly congested sound. A warmer signature definitely isn't a bad thing but putting those pads on the K701 ruined the sound for me. I thought maybe the extra bass might make the K701 more suitable for EDM at least, nope, they just sounded congested. Classical, Jazz, Rock, bad, bad, bad, made the K701 into the worst sounding headphone in my collection. Going back to the K702 with those pads I found no reason to keep them.
I have a Q701 incoming now since I've never heard one. I might just grab a new K701 too, both combined would end up costing me about the same as the 65th ann version anyway. The K701 also has the advantage of being the only version that can be easily converted to balanced without performing major surgery on the things.
