Review on 🎧 Renewed BOSE QuietComfort 35 (Series II) Wireless Headphones - Black with Noise Cancelling by Mark Colbert

They don't block out noise completely, but they block it out quite well. Without them, I hear a lot of "distractions" from the hum of a fan to cars driving by. When I have them, it blocks everything perfectly. But even with high extinction, I can still hear dogs barking or when the neighbor drops something upstairs. But it's so muffled that it can pass as a distant sound. And they are very comfortable! The price is pretty standard for Bose. I would have preferred full noise cancellation. But I think it's good from a safety point of view if you can hear the fire alarm or something similar.
