The 40-hour ANC battery is the real headline here and it delivers exactly as promised I charged these once and used them daily for nearly a week before hitting the warning light. The 5-minute top-up for 4 hours of playback is a genuine lifesaver too. Transparency mode is smooth and natural sounding, great for catching announcements without removing the headphones. Comfortable enough for 3–4 hour sessions with no ear fatigue. The white finish looks sleek and stays clean. Exceptional headphones for the money.
