I like to go to sleep wearing earbuds but to voice not music. This means that one prerequisit is to sit flat and flush with the ear to prevent too much pressure forcing the earphone into the ear. The other is a robust connection wire . I have found many earphones, some quite expensive have wires which fatigue fracture very readily indeed. Do you know of a set which would fit my requirements? Good but not hi fi sound is all that is needed but fatigue fracture proof wire is a must.
