I just upgraded from an XS to a Roku 3. Interestingly, I initially thought the remote's feature of being able to use earphones with it was a complete waste and just a gimmick. Now, I realize that it's fantastic for watching TV in bed with my wife sleeping or to watch TV while she's reading a book or on her laptop, etc.
Anyway, my issue with with batteries. They run out rather quickly so I tried using rechargeables but with virtually no luck. A fully charged set of rechargeables is in there now and I'm getting the annoying low battery indicator. That HAS to go. It's one thing for it to appear in the menu interface but not during a show 100% of the time. Bad thinking there. I KNOW it's low but I'm in bed and would be fine if they ran out while I dozed off. Come on guys. hehe
Also, I've had regular batteries that also resulted in the earphones not being recognized. I'd plug them in and they'd just be ignored.
Lastly, I've also had a few issues of the remote being ignored entirely as well with it sometimes working and then, moments later, having the Roku 3 ignore it entirely.
Are others seeing these issues?
Are you aware that as long as the headphones are plugged in, the batteries are being drained? That's regardless of whether you're using the Roku or not. That means, unless you are actually listening to the Roku through the headphones, the headphones should not be plugged in.
Might that be the cause of your problems?
