Everybody who's ever bought an earphone with an earbud has got a bunch of extra ear buds which are provided with it .use it to make a normal,cheap n good ol' fasioned (yep the ones i was jammin into my ears) earphones comfortable and noise insulated.
trust me it really gives u satisfaction to convert a cheapo earphone into something a bit better (maybe much better) . Also its damaging to your ears to listen at high volumes.
i've found that after using this method to insulate my earphones i have been listening to songs at 18th volume instead of the 23-24th.
