I'm not sure if what I'm experiencing is part of this issue. I'm a semi-new Bluetooth user that only recently started using BT for music at work (wifi). I've used it before when pairing mt last two phones to my car for calls but nothing else. About a month ago I got a pair of BT earbuds and I use them for work for 99% music and 1% calls.
I'm not having any issues with distance and can and have walked well over 50' with no issues. The only time the music started to stutter is when I'm starting to get out of range or there are too many walls between me and the phone.
However, every now and then, even when sitting here next to my phone, I get a pause in the music as well as a slight replaying/repeating of a small portion (maybe a few seconds) of a song. This happens with phone on and off the wireless charger. Now I do want to say that this might be a cause of the issues this place is having with their router. Since I'm now aware that there is an issue with BT, I plan to test this out at home and listen to music for a couple of hours on my home wifi which has no issues and see if the pausing happens.
Seeing that I'm not all that used to listening to music through BT I'm not sure if the random pausing is something that just part of the BT technology or not but this has gotten my curiosity up. FYI, the phone is from Verizon and I've had it from day one.
