QCY M1 pro bluetooth earphone
Earphones
are very small headphones that are fitted directly in the outer ear,
facing but not inserted in the ear canal. They provide hardly any
acoustic isolation and leave room for ambient noise to seep in; users
may turn up the volume dangerously high to compensate, at the risk of
causing hearing loss. On the other hand, they let the user be better
aware of their surroundings. Since the early days of the transistor
radio, earphones have commonly been bundled with personal music devices.
They are sold at times with foam pads for comfort
