A few years ago, the concept of a big earphone was popular with B & O's high-end texture at that time, so some differentiated designs were made. The main feature was the integrated aluminum alloy cover (at first glance today, it was a little apple style!), Simple texture, silicone integrated head wear, some innovations have been made in structure, a retractable structure has been adopted, and some bold matching has been made in the back color matching (the picture is in the back). Rainbow gradually changes color, which seems not high-end enough! This scheme is very difficult in terms of feasibility. Generally, the company does not expect to go back to realize it. Let's take it as an extension of everyone's thinking!

Business style color matching

The rainbow with plastic texture gradually changes color matching, with playing!
