This headphone is really a bliss.. surprisingly it doesn't get much attention. Bluetooth is a huge convencience, in addition to the headphone you just need a smartphone instead of
source+ dac + preamp+ amp + cable (!) setups which are inconvenient, importable, complex and expensive as hell.
Amiron Wireless sounds just quite good, at its price of $700 it sound as good as similar priced sub $1k closed backs (keep in mind you also need $1k amp or DAP with a $1k wired headphone) It sounds exceptional with almost every genre and type of music. The sound signature is perfect, balanced basis and slight v-shape to add punch to low and high end while maintaining neutrality.
It also sounds good with imperfect recordings which is a big plus as well. You may say "just listen to high quality recordings bro" but many of my favorite artists and composers' music are sadly poorly mastered and compressed. They sound unlistenable with some headphones but reasonably good with Amiron.
Make sure that your device has aptX HD. Many flasgship headphones have it, and there some software tweaks to insert aptX HD into an Androice device which doesn't originally support it (PM me for help

)
Some people questionad Amiron's portable usage, I am doing very fine with my backpack. After taking it off put the Amiron into its case and the case into your backpack (Never simply throw Amiron into your backback, it can get harmed and gather dust). And the passive isolation is good enough to wear it at almost everywhere.
