In cooperation with monitoring specialist InEar, Voice Technologies created an earhanger headset that combines a perfectly fitting earphone with a high-quality microphone. The engineers at InEar used complex simulations with more than 500 different ear impressionsas well as numerous wearing tests to achieve a precise fit to the anatomy of the human ear. This ensures optimum stability and greatest wearing comfort for every user. The VT DUO combines the custom-style, superb earphone with the earhanger microphone VT901MKII. The result is a set of excellent high-end components that can be used individually as well.
