My girlfriend has just bought me a brand new 20GB I Pod for Christmas and I would like to know from any other I Pod user which earphones or headphones I should buy to achieve the best sound from them? I travel mainly on the bus and on planes so I would prefer something that can drown the background sound out. I heard that the Sony MDR-NC11 and the Etymotic ER-6i are pretty decent. Also what are the essential accessories I should get for the Ipod. I would eventially like to hook it upto my amplifier. Any help much appreciated and MERRY CHRISTMAS.
