I've been wearing the ReSound LiNX Quattro 9 Rechargeable for approximately 2 weeks.
This is my first hearing aid, but I did have a 2 week trial of the Widex 440 F2 prior to purchasing the ReSound.
The ReSound is easy to insert and remove; I've had no difficulties with that aspect of the product at all.
I have worn it continuously for up to 18 hours. I find it to be very comfortable; there have been several times I've forgotten that I had them on.
They charge quickly and hold charge well so far. Streaming audio with Bluetooth does indeed impact charge longevity. I haven't yet done a lot of experimenting with how quickly streaming depletes the charge.
I have an phome running Android 9 so I have to use the Clip device for streaming. I expect the phone will update to Android 10 in early 2020, making the Clip unnecessary.
So far, I am very pleased with the sound quality. We are still in the process of tuning the device to match my needs, so it will only get better.
I think the device may need some work on streaming performance. I occasionally experience 1 second dropouts on either side from time to time when listening to music or audiobooks. Other devices connected to my phone via Bluetooth do not exhibit these dropouts so I know it its the hearing aids. These is nothing unusual going on when those dropouts occur (not low on charge, no interference from nearby Bluetooth devices, the Clip is with definitely within range, etc.).
Streaming sound is not as good as I expected, but I think I know why:
My hearing needs a boost on the higher frequency ranges, so when streaming plays, that is what the hearing aids do. During normal (i.e. non-streaming) use, the hearing aids provide a higher frequencies supplement to the lower frequencies from my normal hearing. Streaming therefore sounds different because I'm not getting the low frequencies anymore; the hearing aids are acting like hearing aids, not ear buds or headphones.
So, it would be nice if when the device is being used in streaming mode, that the frequency range could be expanded to make it sound more like an ear buds or headphones.
I'll have to talk to my hearing professional and/or ReSound to see if this is possible.
Overall, I like the product. It definitely improves my quality of life which is my primary objective.
