I had a similar experience with my one Pure300 hearing aid. It was returned THREE times within 18 months for similar problems. When my audi finally talked me into getting two HA’s, I was all set to get a Pure301 and MiniTek; but my old Pure300 would not pair with the MiniTek and had to be sent in for repair. She would not even contact Siemens about upgrading my old Pure300 to a newer Pure301 saying that she knew they would make me pay full price for a new pure301.
So, instead, I purchased two Phonak Solana hearing aids. I also got the ICom with the TV transmitter as well as the PilotOne remote (which has since been lost and replaced with a WatchPilot2 remote). The ICom connects the aids to bluetooth devices, but unlike the MiniTek, you will have to have another device for remote control of the aids. The ICom battery life is not as long as I would like it to be, and you have to be careful if you leave your phone on your desk and step into another room because the phone (mine is a Motorola Droid) may disconnect, and you can miss many calls before you realise it has disconnected. Phones that have “autoconnect” will not cause this problem. This only happens when you get the ICom too far away from the phone. When you charge the ICom, be sure not to let the lanyard/antenna flop over (It will cause some of the antenna strands to break and you’ll get lots of movement noise). To try and avoid this, I use a stuffed animal behind the ICom charger so I can keep the antenna/lanyard draped upward at all times as when hanging on the neck. All in all I am happy with my purchase. I have had my Solanas for about seven months and have had no problems. They are a much better quality product that the Pure300 that I had before.
