Even if you consider just the headphones themselves only a 4/5 in terms of quality (which I’d still argue isn’t particularly fair/accurate, but it’s definitely way, WAAAAAAY less so), this is EASILY a 4.5/5 product as a TOTAL PACKAGE!

The normally $150 if bought ala-carte R2R Bluemini adds absolutely freaking RIDICULOUS LEVELS OF VALUE to this just $330 “kit”!!! (Aka, making the wired planar open-back cans themselves basically just “$180″… O___O…)

IMO, these are wired planar magnetic open-back, over-ear headphones that are damn near the $330 price of admission ALONE! (Having roughly similar overall quality drivers to the 2020 Sundara’s but with a very, VERY different, more warm + “fun” & less cold + “hyper-analytical” tuning job, plus a not quuuite as nice build w/ more plastic).

But throw in the straight up “Swiss Army Knife” levels of use case flexibility provided by the pack-in combo R2R DAC + shockingly powerful amp + proper “high-res” [full LDAC & aptX HD support] Bluetooth wireless receiver w/ 2x device multipoint, “R2R Bluemini”?

(Aka ↓
1. As good of BT wireless as exists atm.
2. Wired over USB-C w/ basically ANYTHING.
3. And even both wired & wireless w/ literally ANY other headphones using a 1x female 3.5mm TRRS to 2x male 3.5mm TRS [or other needed input] cable/adapter.)

Well then… That’s IMO essentially a total “game-over” for basically EVERYTHING under $1000 for a first time hifi cans buyer whom doesn’t ALREADY have a suitable DAC + amp setup for driving them… And ESPECIALLY so for the ENTIRE so-called “entry level”.
(Why buy $130 HE400se’s if you’ll still need to spend at LEAST ≈+$100 on the DAC + amp setup you need to use them, when $330 gets you an “all-in-one” kit AND w/ BT wireless!)

And even for everyone else? IMO, it basically invalidates everything under the new $500 Edition XS.

Why get $350 2020 Sundara’s when the $330 hybrid wired & wireless Deva Pro’s are INFINITELY more flexible (+ WAY more fun & easy on the ears for extended listening) for slightly less $, & for only +$150 more the $500 & also wired only Edition XS’ absolutely CRUSH THEM in terms of sound quality???
