This is an interesting discussion. Hearing assistive technology (HAT) has been a lifesaver for many. It is basically 'add on' technology that works with hearing aids and cochlear implant processors. While HAT has progressed greatly in the past 40 years, it has also become more expensive, more complicated, and brand specific.
Non brand specific telecoils have been the connecting link for over 5 decades. BlueTooth connectivity became available a couple decades ago. Both are still in use and definitely worth having in your personal devices. I would not buy a hearing aid without a telecoil.
Until recently, add on products like hand held microphones, which the Roger device is one of, were not brand specific. Some required neckloops that plugged into the device. Others were wireless and transmitted from the personal device to the add on device. When Phonak came out with the original Roger Pen about 10 years ago, it was brand specific to Phonak hearing instruments. However, one could purchase a special streamer/neckloop that could be worn and used with other brands. Those used the hearing instruments telecoils to connect.
By eliminating telecoil connectivity, it seems that some add on devices are now only useful with specific products. So now, the major brands have created their own external devices/hand held microphones that don't require telecoils to connect. So, is that a problem?
Here is the problematic piece. In order to connect to assistive listening systems (ALS) in public venues, a telecoil is likely needed. You no longer have one. BUT, your brand's add on device is probably capable of connecting to an installed loop system or other ALS. That's a good thing, BUT: It means that add on device has to be with you and charged. What if you are in a performing arts center after enjoying an afternoon or dinner with friends where you needed to use the device to participate in a noisy environment? Does the device have enough charge left to use for the performance? Did you remember to charge it the night before you needed it? If so, it will work wonders. Think on this: what if you paid $1500 for that add on device and now you need a different brand of hearing instrument? Hmmm...do you have to buy a different brand specific product for an ALD?
I don't know the answer to this. I do know that the basic, simple old fashioned telecoil, which costs about $15 to include in a quality hearing instrument, can still connect directly to an installed ALS. The only thing that needs to be charged is your personal hearing instrument or cochlear processor. (Or have fresh batteries on hand.)
Advancements are wonderful but they can also create problems that need to be understood. They also add cost to the product. We are now looking ahead to a new and different ALS/ALD technology called Auracast. It is not here just yet, but it has already been included in some hearing aids and cochlear processors.
Meanwhile hang on to your HAT! (I still use my basic Williams Sound neckloop with my laptop, and other audio devices. The newest one I have was purchased on Amazon for $50. I hope they are still out there. Your audiologist should be able to order one for you. I mention the brand Williams Sound because they make a universal quality product.
It is very helpful to discuss these things with others who use technology and who have the same concerns we have. None of us have all the answers. Thanks to everyone for sharing their experiences.
Thus was very helpful. Thank you for all the info.
