Ask a stupid question and you get a stupid answer from lowly paid tech support staff. You asked a confusing leading question and you are going to get some wrong answer from tech support staff. They are lowly paid and they read from a script. I expect them to give out the wrong information if you don't ask a straightforward question.
You also ranted about how Signia doesn't support this and doesn't support that on page 3-4, which were immediately shot down by me with the Signia bridge dongle device.
And you didn't read your Signia manual, does it say it has Bluetooth at all? NO.
If your Signia hearing aids don't say that they come with Bluetooth, why would you ask Signia tech support about Bluetooth profiles (like handsfree, headset, a2dp audio streaming). Ask an irrevelant question and you get an irrevelant answer from poorly paid tech support staff who reads from a script.
BY DEFINITION, A DEVICE WITHOUT BLUETOOTH WILL HAVE NO BLUETOOTH PROFILES, PERIOD. That's like phoning up Honda asking if the Civic has wings and Honda tech support is going to give you some gibberish answers because it is not in his script.
Phonak specifically will say in their manual that their hearing aids come with Bluetooth 4.2 with handsfree profile for phone calls and a2dp for audio streaming. ONLY when you have a Bluetooth Phonak hearing aid would you ask does it has headset profile (which is a no according to the below screenshot).
Even AFTER I proven that there exists such a Signia bridge device exists in real life, even AFTER I told you that you asked the wrong question and gotten the wrong answer from Signia support staff, even AFTER I repeatedly correct you that there is no such thing as "proprietary Bluetooth", you STILL continue to use such incorrect terminology and STILL argue about it TODAY.
HEY, that tech support guy gave you the WRONG information, so you should STOP relying his wrong DIRECT QUOTE once I showed you that the Signia bridge device exists in real life.
A normal person would ask: "I have this Signia model of hearing aid and I like to stream a youtube audio from my computer, how can I do that?"
And Signia support staff would simply answer: "You have to buy this Signia bridge dongle device".
That's how you talk to lowly paid tech support staff who reads from a script.
