Halo Sport uses a lithium-ion rechargeable battery and can complete 8 Neuropriming sessions on a single charge. Battery life is affected by use and other settings, so actual results may vary. The Halo Sport App will notify you when you need to charge your Halo Sport headset.
Playing music on Halo Sport does not affect the battery life.
