Big, Retro Headphones
I just read over this report:
Sound Output Levels of the iPod and Other MP3 Players: Is There Potential Risk to Hearing?
and it's great. I bought a pair of Sennheiser headphones a couple of years back mainly because I enjoy my music and wanted to hear it without it being massacred by earbuds.
I wrote some visualisations for Windows Media Player to see what different codecs were doing to the frequency range too...
So, now when I sit in the office looking über cool in my big white retro looking headphones I know that in just a few short years I'll be laughing at you poor deaf bstrds.
Updated: It's just been pointed out to me that I may be laughing but you won't be able to hear me so it won't matter.
