2.3. Features
2.3.1. Portable
2.3.2. Speakers attached to headband with magnets - Adjustable. This also allows both speakers to be detached and used seperately
2.3.3. Interchangeable headband
2.3.4. The speakers on the headphones can be detached and then attached to a device that amplifies them for home use
2.4. How it works
2.4.1. Electric impulse is sent into the coil which creates its own magnetic field, creates positive and negative poles which interact with the magnet to create pulling and pushing. this vibrates the speaker's membrane to create sound. The individual speaker heads are held onto the headband with magnets to allow the speaker heads to be removed/adjusted easily.
