Just got the new COM-DEX device from Widex for my Unique Passion 440 RICs.
One word, "Wow!". Two words, "freaking wow!".
Listening to music from my iPhone 6 as I type this. Super impressed by the sound quality. Love how I can switch between listening to audio from my phone with surrounding sound, or with surrounding sound muted.
The small device (about the size of a USB stick) hangs around your neck and connects via Bluetooth to your phone. I tried wearing below my clothes and it works fine (so invisible). You can stream music to your hearing aids and take phone calls. For calls, you do need to talk into the microphone on the neck device though.
Connecting to an iPhone is easy (only tested iPhone 6) but I do suggest turning Bluetooth on the phone first, then connect the neck loop cord to start the device.
There is also an app to adjust the hearing aid (volume and program switching) as well as change the directionality (front, back, sides). The app seems a bit flakey though as I've found it sometimes doesn't work after listening to music. The UI of the app is not that great either...so needs some work.
Will provide additional feedback after some more use, so far really impressed and exceeds my expectations (I've listened to "Made for iPhone" hearing aids and *really* did not like the sound quality or size of those devices. Yep, it would be nice to not need the neck loop...but it will still be a while before we can get there technically in the Passion form factor.
Thank you Widex! Please work on the app though
