I just got a new pair of hearing aids so I no longer need these. They were sent back to Signia to be refurbished with new batteries and new receiver wires. The domes and wax filters are new as well. Comes with the factory charging tray. On a full charge these will last approx. 18-20 hours. With the Signia app these will bluetooth connect to your iPhone or Android phone. Phones calls and music can be routed to the hearing aids using the Signia app.
