The charging dock, when fully charged, can fully charge the earbuds at least 4 times.
The standby time for the Vital earbuds is 40 hours.
We listen to music and our audiobooks at all different volumes. We find that most often the preferred volume is medium to medium high making it last 2 hours. Although Vital wireless earbuds can get pretty loud, we do not recommend listening to your audio on max volume as it can damage your ears.
When wearing the earbuds, outside noise is greatly reduced. For your safety, we recommend using only one earbud when bicycling so that you can still be aware of your surrounding.
