It’s going to be hard to get a straight answer on that question. It’s like going online and posting on car forum; what’s better a Chevy or a Ford? I mean you are going to get a ton of answers, and some will be quite heated.
I’ll say this, as a hearing professional who has fitted a significant number of Wi hearing aids, I’ve been blown away by the quality that comes from the binaural spacial mapping. It’s a special and unique way that the aids communicate with each other that creates a ‘surround sound’ kind of situation. By exchanging vital information the aids can work together to produce the best hearing in any situation. By contrast most other wireless aids cannot perform anywhere near the same amount of tandem processing. They can simply synchronize volume or activate the directional mic or something. Starkey is able to stream data between ears at a higher rate than any other hearing system, and this helps cut through background noise better than anything else, in my opinion.
I have taken people out of their high end aids, showed them the Wi, and they have been blown away. While I am not a user myself, I can certainly draw conclusions based on witnessing their reactions.
Now as of right now I have yet to fit a Wi CIC, all the Wi systems I have worked with so far have been RIC. The core technology is the same, but I didn’t want to pretend I’ve fitted a ton of the new CICs.
I think, in reading the consumer website for Unitron, that their top of the line system may have some nice wireless connectivity, which could be useful for Bluetooth and streaming. Starkey is a bit limited in the Bluetooth area as of right now.
Since you have narrowed it down to two systems that your hearing professional likes, it shouldn’t be too hard to try both. 30 days with each, and then make the call. Aids are shipped to a hearing professional on a 90 day sale or return basis. This gives you time to try both sets for 30 days each and then return the one you don’t like. Your hearing professional may charge a small fee for this, but at least then you get to compare.
If you do get to try both, I’d love to read some feedback about it. Last time I fitted Unitron was as a BTE power aid many years ago. Have not really looked at them recently, and I’d be curious to see how they fare heads up with Starkey’s flagship CIC.
Oh and one final thing. If your hearing professional gets annoyed at you asking questions, remind him that that is why he is employed! Geez. As much as they charge for hearing aids, the least they can do is actually answer your questions. It’s not like you are buying a 99c hot dog!
