I recently began my 30-day trial with a pair of Linx 7. On the day that my audiologist calibrated my devices and then went through the pairing process with my iPhone5s, the regional sales rep for ReSound was onhand as well. Since I was only the third person the audiologist had fitted with Linx, having the rep on hand to help proved most beneficilal. In part, I expect that ReSound has been aware of some issues with setup and pairing. And quite honestly, the calibration process based on my NOAH data didn't take very long - it was the pairing and subsequent learning the ins and outs of using my iPjone with the ReSound Smart app that took up the bulk of the time.
A couple of notes about the initial "do it once and forget it" iPhone pairing. Before pairing, the rep had me turn off all apps running in the background. Simply exiting or quitting an app is different from turning off apps in the background. The process involved going to the General/Accessibility/Hearing Aids section as the bluetooth involved is low power bluetooth not to be confused with the initial Bluetooth On/Off found in the first Settings screen.
In the three days since pairing, I have had no issues with the phone staying paired. When I close the battery cases to turn on the devices, they pair with the iphone within seconds. When I turn bluetooth off (using the accesibibility screen for ReSoundSmart app - not the bluetooth on/off in Settings) and then turn it back on, pairing is quick. There was one time where it took about 15 seconds but otherwise, it's been fast enough.
Since the iPhone is our one any only phone (we are full-time RVers and just use the one phone), there has been a learning curve for my wife and I when an incoming call is received. I can hear the caller in my Linx just fine but for my wife to be able to accept the call, she has to switch to "iPhone" in the ReSound Smart app thus rerouting the call out of my hearing adis. There have been a few humorous moments but by in large it's worked well. No dropped calls.
One thing about answering the iPhone is that when I hit the "accept" button, there is a short delay where the screen is grayed out. We were told to wait until the screen assumes its normal appearance (not grayed out) before talking. This takes only a few seconds but until that happens, interaction with the caller cannot occur.
There has been one instance when my wife was on a call that the audio switched to my hearing aids. But we're not sure if my wife inadvertantly hit the iPhone screen, or, if in fact it is a software issue as some others have suggested. We're keeping track and will relay any information to ReSound support.
It's too early for a complete report on how the hearing devices are working but so far, they have worked very well for my needs. I like having control over volume on each hearing aid as well as treble and bass adjustments. Over time, if I like more treble or more base for one or more of my general settings, the audiologist will be able to make the adjustment more permenant.
I have three general programs that were default names: Softswitch, Restaurant, Outdoor. There is the option to add a fourth and I may ask that it be setup for "music". My listening to music experience is that it sounds overal tinny or, overly bright. In part it may be that my brain is still adapting to filtering all the new sounds (walking on gravel in the Outdoor setting - I have to drop the volume significantly).
I find the Restaurant setting works best for enclosed spaces (like our RV) or driving. The Softswitch works well as an omnidirectional as well as the Outdoor which is very sensitive. As a bird watcher I am having to relearn a lot of the sounds I once knew.
The ReSound web site support area has several "training" videos that are mainly for professionals but which I have found to be very helpful understanding the basic technology involved. Probably not for eveyone but worth looking over.
Looking forward to what others are saying. The ReSound web site doesn't have a discussion list so I'm grateful for the Apple discussion area.
