Junglist Agree with you 100%.
I have a few headphones... I just like to try and hear things differently. And as Junglist said, openback keep it on the close office a.k.a. your room. Closed back, like the Sennheiser MX30 - 50x are pretty great for the price, what set them apart is some slight sound differences between them.
Bluetooth headphones, it doesn't matter which one you pick, get any that can be used while charging (must don't) otherwise you will be one day rocking the headphones(or maybe you forget to charge them the night before) and you'll not be able to use them. Logitech Artemis G933 are pretty good for this tho.
Something else, depending of your budge you can grab a Sennheiser GSX1000 or 1200pro (quite similar) and you'll not regret about getting wired headphones and having great sound stage. FYI. If you get very powerful headphones you will likely need an amplifier as the Sennheiser GSX is not that powerful for high ohms headphones.
