I didn't need an expensive or wireless hands free product for my cell phone while driving. Just wanted something simple to make sure my eyes stayed on the road for safety. While the ear buds are a little large for my ears, I can hear my calls fairly well, and the microphone works great. The microphone also has a button which allows call to be made with spoken instructions. Recommended for an inexpensive way to keep your eyes on the road while talking on your cell phone.
