The StageDiver is the ultimate universal monitor from InEar. The design engineers from InEar created a monitor that fits in almost every ear and looks identical to a custom made system.
The base for the housing was developed by overlapping over 500 different scans from ear impressions. Several prototypes were manufactured in-house and tested on customers to find the perfect fit so the monitor will not move. At the end of the development cycle InEar had created an almost perfect to the anatomy of the ear universal monitor.
