Normally if you're BLU-100 (or any other bluetooth device) works in doors, be it near to the source or far away, in or not in your pocket/bag, but has issues outside, this is usually down to some sort of interference from either the environment or something else. Usually if you can get bluetooth devices to work fine in one environment and not in the other, then something is interfering with the signal from your source device to your earphones.
Try turning your wifi off when outdoors. Usually phones which have wifi on, but not connected to any wifi network, will try to continually search for networks, this can cause signal interference with bluetooth.
Check also your apps, apps that need to sync a lot or use GPS even in the background will run interference. I would recommend as a control test to simply turn off mobile data and gps and then go out and see if you still get the same problem with your earphones. You may also want to turn off anonymous reporting in your android setting.
Along with the above suggestions, you may want to remove any case you might have on the phone to see if that changes anything.
^ Thank you. What you said makes sense and is consistent with what I read about bluetooth before. I did try each and every suggestions that you provided.
I am not getting any improvement though. I found a particularly bad spot, turned off wifi/syncing/GPS apps/mobile data, take off PLASTIC phone case and even put phone to airplane mode. Nothing improved.
What is funny was that, at that bad spot, my phone reported no other bluetooth device. As soon as I put phone in my pants' pocket and turned around, music would be cutting off constantly. At that "bad spot", there was no people/cell phone/phone visible within 25 meters from me, but there might be many phones within 200 meters from me (the spot was the parking lot of my son's school, time was 5:50PM - many parents with cell phones were probably pesent at the time within 200 meters from me).
My phone is an Oneplus One on latest Cynogen OS (modified Andriod 5.0 Lollipop), if that matters.
