This is a very well made headset that is comfortable and easy to Bluetooth to my iPhone 6 plus. I charged the headphone when it came and held down the button to activate Bluetooth. There were no instructions that came with it but it is so simple and easy to use, you don’t need them.
Next, I went to the Bluetooth settings on my phone and the headset showed up as BH-M10B. Then I held the button down on the headset and it activated SIRI on my phone.
The sound is excellent and crystal clear. Conversations using this headset are pleasant and easy to hear. I wish I had this headset a long time ago, it’s really a huge asset when working on the run. I love the hands-free calls I can make and still stay focused on my driving or whatever else I need to be aware of.
