Hifiman Deva, any thoughts?

My main headphones are the 400s from Hifiman and AKG NC 700cm2. For some time the AKGs have been winning simply because they are sound very good and are so damn convenient, and no cords means nothing of interest for my cats to play with.
In absolute terms I prefer the planar 400s, and the fact they are open back rather than closed back is for me a big deal, (my ears can't handle IEMs and to a lesser extent closed backs) but I'm just not using them much. Discovering the Deva, which hits all the bases of planar, open back, advanced Codecs and Bluetooth has me really interested. If anyone has used them and can comment much appreciated, anyone that has experience of both the Deva and 400s your opinion would be especially useful.
All the reviews I've seen are pretty positive, and some have said they are pretty similar to the original 400i but maybe a bit warmer, which would suit me fine.
Musical tastes are typical 60 year old. Vocals, light classical, piano, violin with some ambient/ chill thrown in. Rap, metal, heavy rock and opera never get played.

not tried them but did look at them before. they have a bluetooth module you plug in. most say they are good with vocals etc and not too much bass.
I will stick with my Nuras(from your corner of world as well):)

Yes, it's that Dac/amp dongle that has me really interested, the convenience really appeals to me. The lack of low bass doesn't worry me, in fact as a tinnitus sufferer it could work in my favour not triggering it. Really see one of these in my future in the near future.
