My Grado SR-80 headphones are more electrical tape than headphone at this point. Inexplicably, sound continues to come out of them. The wires have so many breaks that I'm not sure how this is physically possible.
Also the top of the band is also splitting apart and the pads are worn down and fall off constantly and there are pokey plastic bits that hurt my ears a lot. After prying them apart with a hammer and screwdriver to fix the wires a few times, they look like they've been through a wood chipper. I love those things but it is time for retirement.
Researching headphones can suck up months of your time if you let it, especially if you believe the bullcrap. Going to an "audiophile" site like Head-Fi is like entering a new world. I have no idea what any of the vocabulary means.
"Detailed", "neutral", "open soundstage", I can figure those out to some degree. But what the hell do "sweet" and "dark" and "thick" and "smooth" mean with regard to headphone quality? Are we talking about music or chocolate? What do "forward" and "recessed" and "transparent" and "analytical" mean? These are rhetorical questions, I don't care what they mean. I have my doubts that they even mean anything objective.
Then there are strange beliefs, like that letting your headphones run for 100 hours to "burn them in" when they're new will make them sound better. I'd really like to see that theory put to a proper scientific test. I have strong doubts that it's anything more than people's minds fooling themselves. It sounds like voodoo. At least it's not as bad as $7,000 speaker wires.
I can definitely and easily tell the difference between cheapo $5 headphones and my Grado's, but beyond that I really start to doubt that it matters. Spending hundreds or thousands of dollars on headphones seems like insanity to me.
For this reason I decided to do next to no research, and went and bought the first pair that I found online that looked comfy, got mostly good reviews, got a couple good reviews on head-fi (as far as I could decipher) and had a price of around $100. I ended up ordering ATH-AD700's from Amazon. Should be here in a week.
