Um, this is the headphone thread. You have to buy at least half-a-dozen headsets a year to post here.
I used to have a serious headphone problem (like I have a game problem now), and I couldn't guess how many headphones I have. I've only bought one this year, though, so I'm getting better.
I've had a lot over the years but anymore these days I'm starting to have a "if it ain't broke, don't fix it, and if it is broke, fix it before replacing" type of mindset.
One brand that I used to buy a lot that seemingly isn't around anymore is
Plantronics Gamecom headphones. I don't know why but I really liked them as a kid. I don't remember the exact ones I've had, but I remember one had a button on the left earcup to active "digital surround sound" or something that wasn't true surround. At the time I didn't know much better and thought it made games sound so much better, these days it's probably similar to what Windows Sonic is. It was completely unique to me back then. I was really obsessed with video game audio, so playing BF3 with that surround sound mode and War Tapes enabled in game sounded like I was standing in the middle of the war.
Over the years I'm less interested in achieving the highest end audio. If it's good enough then that's fine to me. As long as it sounds crisp and the EQ sounds balanced then that's perfect for me. I don't like too much bass or too much treble, only when listening to music but I usually set a custom EQ for my audio player. What I like the most out of everything with the Cloud Alpha is the build quality, it seems super sturdy for gaming headphones. Lots of metal, minimal plastic, I really like that.
