List your state of art headphones for smart phone use!


I am looking for over the ear headphones that can play at a satisfactory volume and do not drain the battery.
I currently have Sony Pro MDR 7520 headphones that list at $500 and are on Amazon for $275.
They are comfortable and fairly good for the price.
I use an Audioquest dragonfly cobalt D/A with my iPhone, iPad, and laptop.
If I moved up to $1000 or more what would be much better?
Are earbuds an alternative at all?
At home I use Stax L700 and get very close to SOTA sound quality with a Stax tube/fet driver amp.
I do not expect the same Stax sound quality.
Can I get close to my home headphone quality?

and everything else is going into a box I’d like to be buried with so no one else knows of my mistakes.

Thx Erik!

Made my day, glad to see somebody else honest enough to admit they are capable of making a mistake.... or three!
ERIK with a K,
1) Bluetooth is a distant second to "wired" in sound quality, and not close to SOTA, which is the subject of my post.
2) Earbuds can fit in the pocket for travel, but do not beat headphones for sound quality, and are never close to STAX.
3) You must have never heard STAX headphones which was the sonic baseline in my post.
Some other fine professional headphones.

For critical listening. Value for money.
