Holy shit you guys got technical for self-proclaimed non-audiophiles
I have a pair of Sennheiser HD650s. I don't use them much right now or for the past year, but they will be put back into rotation.
For gaming / voice comm I have a pair of Arctis 7 from Steelseries. Kinda bummed I didn't go for the Wireless HD.
I have a pair of Sennheiser 280 Pro's for tracking while recording audio. They are closed-back and have good passive noise reduction in that they are almost like hearing protectors with headphones inside.
I also have a set of Steelseries Siberia 800. They used to be what I use for gaming / voice com, now I actually use them for wireless monitoring of my guitar rig when I dial in guitar tones, or for A/B'ing stuff. Or previewing stuff. Then I disconnect them and send the signal to speakers. I have a pair of these:

They are FRFR speakers in guitar cabinet format. I have two that I run in stereo. They are probably my "best" sound output of them all. The quality is really nice. Due to how they are constructed with a tweeter in the upper right corner and the mainspeaker in the middle but a little down and to the left,, they aren't good for actual stereo image representation. It's close enough that I can't audibly tell that the stereo imagine isn't perfect, so good enough for everyday use. They are guitar amps really, they just happen to sound awesome as studio monitors and hifi speakers. After getting into guitar playing I've come to have a deep appreciation for how sound behaves in a space. Moving around in a room with headphones and having the sound come out exactly the same wherever you go feels weird now that I've gotten used to speakers that have a field. When sound waves bounce around in your room there'll be spots where they cancel eachother out, and there'll be points where you'll have resonances, so that moving around in the room while sound is being produced by a speaker in a static position is actually a dynamic experience. With headphones it becomes static. I've come to realize that headphones are unrealistic by their very nature, and that they're like a smokescreen or something. An induced illusion. They're still superior for certain specific tasks though, like comparing one piece of audio with another. Another important part of the experience of sound is the physical effect sound waves have on your sensory nerves. You don't only hear sound, you feel it. That part of the experience also falls short when using headphones. There are no moving air molecules hitting your body in thousands of waves per second. With headphones, you hear the sound, but you don't feel it. I'm doing all I can to get away from a cerebral lifestyle. I want to feel the music, not just hear it. I want my brain and body to act and react in tandem.
