Signia Pure Charge & Go - All In-One-Hearing Aid | Hearing Aid Reviews Within the past few months Signia released the Pure Charge & Go Hearing Aid. It received a lot of attention due to the Own Voice Processing (OVP) capabilities of the devices. They are impressive because they can do just about everything. #1. They are rechargeable - They use Lithium rechargeable technology which provides 19 hours of battery life without streaming and 17 hours of battery life with 5 hours streaming. The devices also turn on immediately after removing them from the charger. The only thing I don't like about the charger is that it doesn't have a dehydrator kit built in. #2. It has the Broadest Wireless capabilities of any hearing aid - You can connect directly to an iPhone for streaming audio and phone calls to both ears. You can connect to an Android phone and TV, but it requires a StreamLine accessory. The myControl app is excellent and allows for numerous adjustments. #3. Tinnitus Relief Feature - Signia uses Notch Therapy. This helps by stimulating the nerves adjacent to your tinnitus frequency to help reduce the perception of your tinnitus. #4. Own Voice Processing (OVP) - OVP delivers the most natural-sounding own voice when the wearer is talking by processing the sound of his or her voice completely independently from all other voices and sounds. Overall, the Signia Pure Charge & Go hearing aid has nearly everything you could want in a hearing aid.
