Description

Bluetooth headset with expandable stereo and earbuds

technical field

The utility model belongs to the field of earphones, and in particular relates to a bluetooth earphone capable of expanding stereo sound and externally connected to audio equipment.

Background technique

Existing bluetooth earphones can be divided into two kinds of monaural and binaural. The monaural bluetooth earphones are simple in structure and easy to use, but there is only one earphone that cannot listen to the stereo sound, and the listening effect is poor; while the binaural bluetooth earphones , it is necessary to lead out the second earplug through electrical connection, although the listening effect is good, but the structure is complex and inconvenient to use. Single-ear Bluetooth headsets and binaural Bluetooth headsets have their own advantages and disadvantages. In some applications that require high convenience, single-ear Bluetooth headsets are more practical, such as talking on the phone while walking; while in applications that focus on listening effects , Binaural Bluetooth headsets are more practical, such as listening to music. When users choose, they will inevitably lose sight of one another, so there is an urgent need for a Bluetooth headset that integrates the advantages of a single-ear Bluetooth headset and a binaural Bluetooth headset.
