No I don't already have the wired version, but I like the Beyer sound and am interested in the Xelento for a while. Since the Bluetooth wireless version has been announced for more than a year I have been waiting to get one, if not for the wireless module for those times convenience is more important, but also for the flexibility when I can easily swap them out for wired use with my own MMCX cables for maximum quality. If there is no wireless version of the Xelento, I would have gone for the Final E5000 for almost 1/3 of the cost. Both are DD designs and this is what I am most interested in (already own the Shure SE846 with quad BA drivers).
I didn’t care for the Final sound nearly as much as the Xelento, but my ears may be weird. There’s a liveliness to the Xelento that was hard to match... I think the closest was when I took a set of JH Layla’s and managed to get the bass tuned exactly to my preferences — but that’s a $3k headphone.
