This 2 pack of 3.5mm Earphones with microphone built in, and noise cancelling capabilites is a great idea for having extras around. My teenagers are always borrowing mine and forever breaking them or losing them. I kept a pair for myself, and I like these so much they are NOT getting them. The noise cancelling is great if you are on the phone! These work every bit as good as my bluetooth headset ever did for phone calls, and the nice thing is they are lighter and I can listen to music or videos while I am waiting for that phone call. I have decided to keep both pairs for myself.
