Personalize your headphones and enjoy music with the Dyson Ontrac Copper with earbuds. This way, it's clear that they belong to you and fit your preferences. The headphones feature noise cancellation, allowing them to dampen surrounding sounds. This helps you hear less of the noise and focus in a busy environment. With a battery life of 55 hours, you can listen to music for days without needing to recharge the headphones. When the battery runs low, you can recharge it for 30 minutes to get an additional 9.5 hours of music. In the My Dyson app, you can adjust the sound settings to your liking, including the highs, mids, and lows through an equalizer.
