A:Answer Thank you for your question. Although many customers report using the QuietComfort 35 wireless headphones when mowing the lawn, it is important to remember that they are not sweat-resistant. If you are looking specifically for noise-cancellation headphones, these would currently be the best option. If you are looking for better durability, specifically sweat-resistance, we'd recommend taking a look at our SoundSport line of headphones. These headphones, however, do not include active noise-cancellation technology. We hope this helps! - Brian
