Sorry I didn't post earlier.
Have been using the UClear 100Plus for a couple of weeks. Sound is great. There is a little more muffling of my voice when using the phone, but, it is still clear. Just have to learn not to mumble.
Have not used the intercom with anyone else yet.
But, I did pair the intercom with my old SENA SMH-10. This was also where I learned something important.
The current intercom systems will pair with other brands. BUT, and this is a big one, they do not use the intercom circuit!!!!!! They use the headset to phone bluetooth connection. What does that mean? Much less range, ie, how far away from your phone can you get before you lose the connection. Usually advertised asabout 30 ft, clear line of sight is usually closer to 50-100ft. I will be testing this next month with my brother. FWIW, this is not limited to the UClear, it applies to the SENA as well.
Seems when the headset mfgs went looking for a common standard they just went to the phone connection instead of coming up with a standard for the intercomm itself.
This one made me upset cause it is not mentioned in any of the reviews I read, and, it is a VERY important distinction.
So, if you rely on the headset for intercomm a lot, then get a common mfg model.
Back to the UClear. Best part is no boom mike on my modular helmet, and, the sound seems a bit better. But, that is probably due more to less noise in the new helmet (Symax III vs Shoei RF1100).
How loud can it be? A LOT! UClear specs the output of the system speakers at 140dB!!! Well beyond hearing damage. Plenty ould enough that the sound is pretty clear even with ear plugs at 80mph. I will probably be able to listen to audio books now (again, possibly due to new helmet as well as the headset).
One IMPORTANT installation note. The angle of the speakers in the helmet has to be EXACTLY the same on both sides. If they are off by even 5 deg your voice will sound muffled or you won't be heard at all. The noise canceling part uses that angle between the mics to shut out the excess noise. So, if misaligned they shut out your voice too.
