I only have £25 to spend on headphones, and need a pair of preferably overhead headphones which have good sound cancelling as I use top volume on a school bus I don't want any leakage and provide high quality sound, for use with an iPod classic. Mainly listen to 'Screamo', Acoustic and Dubstep. So they need to be able to cope with a range of sound and volume levels and some heavy Bass. Need a cord length of at least 1.5m, jack size 3.5mm Any help would be incredible, and anything ASAP would be perfect! Also, would be helpful for ordering from Play or Amazon.
