Query: Sturdy, Comfortable, Good Sound

I needed headphones to use in a workshop situation where I have 10-20 people listening to a single sound source. When I saw these headphones with the extra long cords and volume control, I was instantly sold.The straight style cord is good for bundling, storage and moving. I have another pair of headphones with a curly cord that is a pain to untangle after they have been in a bag.The over the ear cup design is perfect to insulate people from outside sounds. They are adjustable for different head shapes and sizes. The sound quality is good (not excellent), but adequate for my needs. They are sturdy, so I don't worry about them getting broken during transport.If you are buying many headphones for public use, I really think these can't be beat.
