Summary: You won't get the best noise-canceling performance with the Motorola H780; for that, go for the Aliph Jawbone. Even the Jabra BT530, also $99.99, offers slightly better noise cancellation and a sturdier fit (and it comes with a car charger, to boot).
Conclusion: Overall the H780 continues in the trend of previous Motorola headsets, giving your great performance. The inclusion of a proper power switch does make things simple and overall we had no problems with the performance of this headset.
Pros: Simple, noise cancellation works
Cons: Noise cancellation button is pointless, questionable styling, price
