Pure is equipped with the latest version of BestSound™ Technology which allows wearers to understand speech in demanding listening environments, even better than those with normal hearing.* This world-first advancement is a complete revolution in audiological engineering and delivers a perfect balance of rich, natural sound quality and audibility.To localize sound sources, maintain spatial orientation, and understand speech better, our brain utilizes information from both ears. This is especially helpful in noisy and challenging listening situations like restaurants or parties. Inspired by these advantages of hearing with two ears, or binaural hearing, Pure brings you cutting-edge technology to deliver the most natural binaural listening experience possible.Siemens Pure models do all this with the industry’s lowest battery consumption.** This provides the best listening experience, all the time, without concerns about battery life. * Clinically proven in two independent studies.
