## Before you buy

- The listing details are inconsistent about noise control, describing both open-ear listening and Active Noise Cancellation. It also lists a 3.5mm Audio hardware interface while separately specifying No Jack. The listing calls the design True Wireless despite describing bone conduction headphones. Clarify these details if they affect your choice. Bluetooth is stated not to work underwater, so use MP3 mode for swimming. The stated immersion limit is 2 meters for 2 hours.
- The listed 8-hour battery life is a manufacturer claim. Actual playback time is not specified by operating mode.

## Customer feedback

Customer feedback describes the headphones as comfortable, lightweight and secure-fitting, with positive impressions of sound quality and water resistance, including use for ocean snorkelling.
