New Signia Active Pro IX features on-to-go rechargeability, automatic environment sound-sensing, direct-to-smartphone Bluetooth connectivity, all in a stylish, earbud "wearable" form factor for mild to severe hearing loss. Signia Active Pro IX has more features than the regular Signia Active Pro IX product: wind noise suppression, reverberation and echo reduction, sound smoothing, speech auto-focusing, directional microphone control, and microphone directionality control. Speech is automatically tracked and enhanced even from multiple sources and while no matter if the wearer is in active motion or not (4D Multi-Speech Tracking) The included charger doubles as a portable power-bank and case for the Signia Active Pro IX hearing aids. The innovative charger holds up to three (3) full charges. Each four-hour "full" charge provides Signia Active Pro IX hearing aids with enough power for all-day-and-all-night hearing (approximately 26 hours of energy). Just a three-hour case charge via USB cable, or a five-hour case charge via Qi-wireless charging, provides a bit more than three days worth of hearing aid charging on-the-go! For added flexibility, you can also "quick-charge" Signia Active Pro IX for 30 minutes for 5 hours of usage or 3 hours of streaming. The charging case can be charged by USB-C (included with charger) or via any Qi-wireless charging pad or device (sold separately). Signia Active Pro IX can also be connected to any Bluetooth smartphone for wireless calling directly from your hearing aids. Volume and environment setting controls can be changed easily via your smartphone (free Signia app) or a miniPocket accessory (sold separately).
