Guys I have new 2nd hand w715 & an old w660i & 3 bluetooth units which I use cordless earphones.
1 x Motorola s9 those wrap around the back of your head headphones.
2 Sony Eric stereo bluetooths HBH DS200 & DS220.
All 3 units work fine with the w660i but the newly aquired w715 cannot locate any of the bluetooths. All it can see is the w660i. Are the above not compatible with the w715? Surely its my error. All units are fully charged. Could it be I have to delete them from the w660i first? Any clues?
