Long before true wireless earbuds’ era, we once had this personal sound amplifer that look much like TWS today, but they are not for listening music and Bluetooth transmit from your phone.
According to FDA, personal sound amplification products (PSAPS) such as sound amplifying earbuds are intended for non-hearing-impaired personals to enhance the sound in certain circumstances, not for those with hearing loss.
Just a few sound amplifying earbuds on the market here are among the top that offer the solid sound amplification.
