Personalize your headphones and enjoy music with the Dyson Ontrac Copper with earbuds. This way, it’s clear that they belong to you and suit your preferences. The headphones feature noise cancellation that dampens surrounding sounds, allowing you to hear them less 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 is low, you can recharge it for 30 minutes for 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.
