These headphones with built in microphone for answering calls, have amazing sound quality. These are wired so they are great when I wear my phone holder on my arm and walk with the dog. In fact they are great whenever I use them. They go right into my Samsung phone and right into my ears! I can use the built in microphone for talking to someone when they call. I love that this came in a 2 pack. I use one and the other one I keep in my purse for later. The wires are pretty durable and don't get tangled up easily. They are now my go to walking earbuds!
