Bluetooth Headphones Lightweight AX8 V4.1 Wireless Sport Stereo In-Ear Noise Cancelling Sweatproof Headset with APT-X/Mic for iPhone 7 Samsung Galaxy S7 and Android Phones

I'm getting mixed messages from these headphones.  Directions are good, I am frequently a severe critic on directions.  These were good.  I charged the headphones and then set up to pair them.   I initially tried my Samsung TabS and I could not get a pairing.   I then successfully paired the headphones to my Samsung S7 and to my Amazon Fire.   I tried the telephone capabilities on the S7 and that worked just fine.  I listened to Pandora for awhile and that too worked fine. So as far as function, I see no problems with this headset.  Now my concerns the cord is both conveniently and inconveniently short.  It doesn't get in the way but the volume and MFB (multi function button)  are out of sight and every change is done blind.  Now if your head isn't as big as mine, you may have enough slack in the cord to see what you are doing.  I would have no objection to a larger control button.  However the control button is basically similar to those on other Bluetooth headsets I have tested.  Besides the unknown reason it would not pair with my Samsung tablet and the inability to see what I was doing, the headset is just fine.  

The music was clear as was the phone.   For me a larger visible control button would take this from a four star product to a five star product.

I received this headset for free in exchange for an honest review.
