Your best best is to use something like the ES100 by Radsone. Great battery life, has an app with EQ, and supports LDAC amongst many other features. Even the Fiio BTR3 and many other devices offer a superior experience nowadays.
Unless you're aiming for a no wires experience, Shure, Westone, MEE, etc. all make a compatible Bluetooth cable. They're just expensive, don't support the latest codecs, and have poor battery life by comparison.
But really, just get the ES100 and enjoy great sound quality. If you need more power, devices like the iFi xDSD can also power over ear cans as well if you're looking to have more flexibility. Though it does come at a higher cost.
