My wife loves these, especially since they came with an attachment to help adjust the size so that they don't slip on her neck so much. The noise cancelling is pretty good and the sound is great. The one thing she doesn't like is that the buds hang from the headphones instead of hooking on or attaching with a magnet or retracting like other models.
This headset turns off after about ten minutes of non use. Which means you are constantly having to power them back on. The volume on them are extremely low.
