Answer to: will not pair with iPhoneThis solution WORKED for me. I have: iPhone 7S and Jam Plus HX-P240 (3 yrs old, circa 2015) My iPhone showed Jam speaker but showed "connection unsuccessful" when I tried to pair. I tried several fixes including resetting the speaker. Nothing worked until I followed the chosen suggestion. 1) Turned Jam Plus speaker OFF. 1) In iPhone bluetooth settings selected Jam Plus, hit the little "i" button & selected "Forget this device". 2) Turned Bluetooth OFF on iPhone 3) Turned JamPlus ON and held down the power button AND "+" button (I did this with left hand - I'm right-handed - this left right hand free to do step #4). 4) Simultaneously in iPhone settings, turned Bluetooth ON (still holding down the speaker power and + buttons). 5) iPhone discovered the Jam right away. I selected it & it connected! NOTE: To test I turned both off several times & each time it connected JUST BY TURNING ON. I did NOT need to hit the "+" again.
