Easy to listen to headphones, that dont require you to actually listen (you wont know what i mean untill you here some demanding headphones). Brands like Audio Technica, Sennheiser are good for this.
Try the audio technica ATH-CK7, i personall favourite for cheep headphones.
Ignore any bad reviews, them people are either comparing them to more expensive headphones or are plain stupid. I've probably herd over 100 headphones and owned 50, they are good - trust me.
