Phone calling is a two-way proposition. There’s sound in, and there’s sound out. Both should be loud, and both should come in clearly, meaning DSP, ANR, CVC, and whatever other abecedarian high-tech noise suppression algorithms that technology can fling at it - plus loudness, in abundance. Besides talking loud and being heard, you need to be able to listen, unless you’re running for office.

BlueAnt’s Supertooth Light performs exceptionally well with incoming sound, but falls a little short on the outgoing. Loud is good. Loud outgoing is good, too, and just as important.
