“How many hours of battery does this have? How heavy is it?”

1-5 of 5 Answers

• They are very light. This is one of the reasons I chose these ones. The battery lasts a long time. I’ve used mine on 3 flights as well as while mowing the lawn and the battery is still about 50%.

• Hello, D! Thank you for your interest in the QuietComfort 35 Wireless Noise Cancelling Headphones II. The QC35 II offers up to 20 hours of wireless listening, and this increases to 40 hours when using the back up 2.5 to 3.5 mm audio cable. The headphones are engineered to stay cool and comfortable, even after several hours of use. The weight of the product is 10.88 oz (310 g). We think you'll really enjoy them. Have a great day!
