Stock iPod ear-phones
It's not that the stock ipod ear-phones are bad, it's that they seem to leak more music into the air around you, than into your ears. Mostly when I'm standing within 5 feet of someone with an ipod and the stock 'phones i can always hear exactly what song they are listening to. Of course on Londons tubes and trains, 5 feet apart from your fellow commuter is a physical impossibility, so I say this to ALL iPod users who are still using those leaky-noisy stock ear-phones (the one's it came with) - GO OUT AND BUY SOME DECENT EAR-PHONES. Please. Or I'll have to stab you with my brolly...
