Today I combined the best aspects of headphones and earphones with a quick retrofit. The design allow the user to attach the headphone section to the back of his/her neck, allowing structure from one 'mandibel curve' (jaw bone's point, below the ear lobe), around the back of the neck to the other side, whist the free hanging earphone sections are still free to inserted into the ear but excessive wire movement is restricted. This improves both the flexibility and stability problems experianced previously with the headphones and earphones (respectively).
The retrofitted headset is very comfortable and stable, but is not restrictive at all. (This made my MoodMonster excited...)
PS. this is my first entry, will improve ASAP. Please comment and/or try it!
