I'm looking at purchasing either a pair of Hearphones or some of the new Quiet Comfort 700 headphones to use when my partner and I are on long drives. We like to read to each other, but noisy pavement often makes that impossible. It looks like either or both of these products could work for this, but in the case of the headphones, we would need to use them to make a phone call from her phone to mine, and essentially be on the phone the whole trip. I am wondering if the Hearphones would be a simpler and just as effective way to make this happen.
Question: will the Hearphones mute/cancel the ambient loud noise EXCEPT for voice, and let the reading voice prevail?
