Hearing aids of the past often limited the wearer’s access to many personal audio devices such as mobile phones and music players. For example, to use a music player while jogging, you would have had to remove your hearing aids to accommodate a pair of earbuds. However, today’s sophisticated wireless hearing aids, such as the W2 Bluetooth from Jinghao Medical, use Bluetooth technology to make it possible to connect with personal electronic devices and stream signals directly to hearing aids.
