I have definitely noticed that my TV streamer + OPn performance gets squirrelly on Day 5 of my PowerOne batteries. Without a lot of TV streaming, these batteries will last into the 6th day, but since I do tend to stream a couple hours of TV each night, typically on Day 5, things start to get squirrelly. That’s when I just go ahead and change the batteries.
Not only does the sound quality shift from that “stereophonic” richness you describe to a flatter, 2-dimensional type sound (albeit still streamed directly into my aids!), but the aids will continuously STOP streaming from the TV, and the program will even go from TV streaming back to default Program 1 like some kind of dumb robot taking charge of my aids.
I actually find the Duracell batteries from Costco TIP-TOP! I’ve been getting them for ages now. But occasionally, if I’m on the road, or lazy, or SNOWED IN, I order batteries online at Amazon.com. Then I’ve tried the PowerOne size 312. But IMO this brand is not significantly better than the Duracells!
Reading about all the problems others experience with streaming from the iPhone, tho, makes me wonder if Oticon has this streaming thing down pat, or if they wanted to just ride the coattails of some BIG NAME like Apple. Users like me, who have an Android device and refuse any IoT of things are left high and dry. I did put an email in to Oticon asking about the status of their clip-on streamer, and know from experience it will be close to 3 weeks before I hear back from anyone there.
One thing I CAN say about my old Agil Pros and the Streamer Pro: BEAUTIFUL connection. Every time. No clicks, drop-outs, buzzing, zero! Just 100% reliable streaming into the aids. Now why can’t Oticon do that with a NEWER model of aids? At this rate, their next introduction will be a tin funnel to place in our ears, and we’ll be told to have those on the phone or in the room just YELL LOUDER. >:-/
