Everyone hears differently, which is why the Nuheara IQbuds2 MAX Ear ID Earbuds adjust to your personal preferences. Thanks to their Ear ID technology, they can self-calibrate to the settings you enjoy. The connected mobile app can assess your hearing profile through a clinical test. These ANC earbuds then optimize their sound profile to your personal hearing. And with three microphones, the IQbuds2 MAX in-ear headphones offer hybrid noise-cancellation technology. They analyze sound that’s inside and outside your ear to recognize what you do and don’t want to hear. Once they know your hearing, the earbuds let you start and stop your music with easy touch and gesture controls. Finally, these headphones resist both water and sweat, so they can handle the rough-and-tumble life you lead.
