I am relatively new in my audiophilic journey, I got a Sennheiser HD 450 SE as my first headphones a year and so back,I also have Sennheiser btd600 for wireless audio , i sometimes use it wired and I like how they sound with dts audio processing- music option, my laptop have sound by harman kardan so i suppose the inbuilt dac they provide is from them aswell, i am looking to optimize my existing setup to get higher audio quality ,please advice me how can i do so,what settings or equalizer applications i can use for better audio ,currently using spotify premium but planning to switch to apple music by this month end.

P.S.-I prefer wireless as my primary option
