Digital Sound Quality: The Go Pro hearing aids provide users with exceptional, crystal clear sound quality that is much cleaner, and crisper than the sound quality received with some analog hearing instruments. Open-Fitting: The Go Pro hearing aids are designed to sit in the ear more comfortable than many hearing devices. Whenever something is in the user s ear, it has a tendency to feel clogged, and can make the user s voice sound different to themselves. With these hearing devices, the user s ear is less feeling unplugged, and their voice remains sounding natural. Feedback Cancelling: This advanced feature can help eliminate the whistling that can occur while on the phone, or while making volume adjustments to the hearing aid. With this technology, users can make much more pleasant phone calls to his or her friends and family, without having to worry about embarrassing whistling. Automatic Noise Reduction: This feature helps to dampen the cumbersome sound of background noise in loud environments. With background noise selectively reduced, users can focus on what they want to, like conversations. This feature can also help reduce the mental fatigue that can occur over extended periods in loud environments. Directional Programme: The models of the Go Pro hearing aid feature a directional microphone that helps users pinpoint speech sounds in front of them, while reducing the sound from other directions. This can help further enhance the ease with which users can have conversations in noisy environments.

* Artificial Intelligence: This advanced feature allows the user s Tego Pro hearing device to automatically make adjustments to the settings of his or her hearing device as the user moves through varying sound environments. With this feature, users can make much fewer manual adjustments to his or her hearing aid. This feature can also help automatically reduce background noise in the user s environment. * DecisionMaker System: This hands-free feature helps ensure that the Tego and Tego Pro user always have the best sound quality possible, without any manual Programswitching. * Noise Management: This multi-band noise-cancelling technology helps reduce constant background noise that the user hears from his or her environment. Situations like eating in a crowded restaurant, or driving in a car, can become mentally exhausting to hearing aid wearers. With the Tego and Tego Pro, however, this background sound is significantly reduced, and they can ignore sounds they do not want to hear, and focus on sounds they do, like conversations. * HF Direct: This feature helps provide enhanced speech clarity, allowing users to have easier, more comfortable conversations. * Adaptive Directionality: This feature provides the Tego Pro hearing aid with high-precision in attenuating noise, allowing users to focus where they need to. * Open-Ear Acoustics: The Tego and Tego Pro hearing aids are designed to be worn very comfortably. They are intended to fit in the user s ear with the least occlusion possible. With some hearing aids, users ears can feel plugged. However, with the Tego and Tego Pro hearing aids, the users ears remains feeling natural. This means that the user s voice will continue to sound normal to the user themselves.
