This works wonderfully in quiet environments. But the moment you have any significant background noise, and need noise-cancelling headphones, this ends up being useless because no headsets do noise cancelling over a headphone jack - only internal batteries or USB connectivity.

Even with those rare wired-optional headsets that accept headphone cords, the noise cancelling functionality gets shut off the moment you plug the headphone jack in.

My Sennheiser momentum 3 wireless (the cans not the in-ear ones) are cable-optional and do noise cancelling with the cable attached as long as they have battery left. In case you're like me and REALLY need that combo of features.
