Title: Noise cancellation is worthless.
Review: The noise cancellation function is worthless. I could detect no noise cancellation whatsoever.Specs claim 10dB attenuation at 300Hz. I tried a tone generator and could detect no attenuation at 300Hz either.The product seems to amplify headphone output a little, but this does nothing to background noise. The amplifier does add noticable hiss too.I'd have given this product a zero if I could have.
