For instance, with my hearing aids, my cell phone has a Bluetooth capability and can be turned off and on. I hold my hearing aids next to my phone and turn on the Bluetooth. A menu comes up with a list of things to connect. My hearing aids have an assigned name. I tap the name and the aids are paired to the phone via Bluetooth. The headphones hook up the same way. I have the headphones turned on and hold them close to the phone. I turn , the menu on the Bluetooth shows the connection name of the headphones, I touch the name on the screen and the phone and headphones are paired and I put them on and start listening. If you get the headphones it is very intuitive. You'll have no problem. I scrolled for 4 1/2 hours this afternoon and the headphones were absolutely comfortable. The sound streams directly into my ears and there is absolutely no outside noise. Dead silence. I could not be more pleased. Of course I remove my hearing aids. I can't listen to music as the change in harmonics a frequencies are just garbled. However, speech is crisp and I can listen to podcasts. There are some speakers that are easier than others to understand because of difference in their speech. So far I have not had a problem. They bring a whole new comfort to scrolling! I'm sure all cell phones now days are Bluetooth.
