Feels sturdy and durable as well. The person on the other end is still able to hear some background noise. The blades I would buy from the store (Target, Walmart) used to have a blue lip, as seen in my photo. The decision to include this kind of installation hardware is thoughtless and stupid. A+++++ customer service. I liked it so well that I bought a second one just for me! Wearing a 7 wide. Which is what you want from a hard shell case. The base is nice, big and heavy enough to keep it sturdy. At home, I unboxed the ANC7Bs and plugged them into my MP3 player.
