Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth headsets, in particular to an open Bluetooth headset with a self-selectable noise reduction level. Background Art

[0002] Open Bluetooth headsets are a relatively popular type of headset at present. Since there is no in-ear rubber sleeve extending into the ear canal, they are more comfortable to wear, suitable for long-term wearing and various sports scenarios. The sound of the headset can be conducted into the ear through the gas medium, and the wearer can also hear the external sound synchronously. In different usage scenarios, users have different requirements for the noise reduction effect when using open headsets: in a normal environment, they need to balance the sound quality of listening to music and also be able to listen to the surrounding environment sounds. By replacing different rubber sleeves, the physical noise reduction effect of the headset can be adjusted so that the sound of the headset and the surrounding environment sounds can be heard clearly at the same time. In a relatively noisy environment, it is hoped that the headset has a better noise reduction effect, combining physical noise reduction and the active noise reduction of the headset to remove part of the external noise in certain frequency bands so that the music or call sound of the headset can be heard more clearly.

[0003] Generally, the open Bluetooth headsets on the market do not come with noise reduction rubber sleeves. Users cannot adjust the noise reduction level of the headset according to their usage needs. For users with multiple noise reduction level requirements, they need to purchase multiple headsets with different noise reduction levels for selection, or prepare multiple noise reduction rubber sleeves with different noise reduction levels and suitable for the headset by themselves, which is more troublesome to use, with a poor usage experience, and increases the usage cost of the headset.
