Here's some text from Aiaiai:
--
Tracks Headphone Series (headphones & headphones with microphone) are on-ear headphones inspired by the function and design of the old iconic walkman headphones.

The design of Tracks is subtle with a clear focus on organic lines and an overall iconic shape.

The simple brace design fits all and ensures a comfortable and secure fit. The slider connecting the ear cup and the brace comes in three sets of different colours for customization.

For disassembly you can easily slide off your ear cups and pack them securely for transportation or share your music with a friend on the road. The headphones come with a neat carrying bag for protecting the different headphone parts and keeping the wires from entangling with other items in your bag.
