Bluetooth poor range

[Whitewheels]

Just got my m4 back from a almost 5 month long repair. Anyway. The Bluetooth works fine with the incar stereo for sound and phone but when I conect to my peltor and bose headset it start cracking up just from a meters distance. My old budget samsung had alot of issues but I could go at least 10 -15 meters from the phone before it started cracking up.
Any ideas?

Have tested bluetooth after pcc repair. Same poor range. Have disable wifi. With the phone in my legpockt and my peltor conected the sound is breaking up. Chest pocket it works fine(like 2-4dm from headset). Can't find the messege with 100m bluetooth yet but don't know how thts gonna make my bluetooth range. If I could.get like 5m in free air I would.be a happy camper.
As I said in my "dubblepost" something most have had happend. Wifi range is a catastrofy!
From beginning of dec 2015 have there been any major update?
Have search the forum on wifi problem and there is a lot of post......not many solved though.

I have 2 "trusted" bluetooth devices now and used to have two more. But as far as I know you can only have one conected at once. Or?
