First thing that scared me was that a lady screams "ANC ON," "ANC OFF," and "BE AWARE" in your ears at loud volume regardless of your playback volume. For now, it gets a 1/5. And you do get mixed packs to trial. These shoes are a little pricey, but they check all the boxes. These are horrible. Very cozy and comfortable. The price on these headphones is really good, and even though they are inexpensive, I expected them to last a little longer than they did. The sound stage is wide and not at all muddied. A usb cable powers it and there are 4 usb ports on the front tidy tidy tidy. These were way too small.
