Luckily, this year’s Prime Day—running from July 8 to 11—includes real deals on noise-cancelling headphones that won’t empty your travel fund. Want to upgrade to stronger adaptive ANC, 60 hours of battery life, ultra-fast charging, and more? Battery life hits 40 hours. Battery life is solid. Because they still hold up with big, punchy sound, 30-hour battery life, and some smart noise cancellation.
