Choose from the small, medium or large earbud gels included with the product to find the right fit for your ear. Hear and feel your music with powerful, oversized speakers that lock in the sound. It’s the kind of rich audio you’d expect from over-the-ear headphones, in an ultralight and comfortable on-ear design. Plus, it has a battery life of up to 9 hours of playtime. Hear and be heard with HD audio quality and amazing dual-mic CrystalTalk noise canceling technology. And carry your conversation further, with up to 300 feet of range with call clarity every step of the way. The VerveBuds 500 uses the latest Bluetooth 5.0 technology which offers reduced power usage, longer battery life, improved speed of up to 2 Mbps and greater range of up to 800 ft (4x more than Bluetooth 4.2). Use either earbud as a mono bluetooth headset to take calls, use the compatible voice assistants for directions and traffic updates or listen to music in one ear.
