V-Powerbuds Pro TWS Earbuds Support Heart Monitoring & Oxygen Tracking (Crowdfunding)

Vimai V-Powerbuds Pro Multi-function Sport Earbuds Vimai’s V-Powerbuds Pro TWS (True Wireless Stereo) earbuds are multi-function wireless earbuds. In the past, we had reported on the Misfit Specter Bluetooth earbuds that could track fitness input, such as steps, calories, and sleep duration. V-Powerbuds Pro also tracks heart rate, oxygen, and respiration, and supports online & offline voice control. The Component Basics The V-Powerbud Pro are TWS earbuds and have a built-in pulse oximeter to capture heart rate and oxygen levels right from within the ear. The hook design holds the earbuds tightly in place, within the ear, to get an accurate measurement independent of the effects of light. Other types of fitness tracking devices like those located on the wrist, can be affected by light. The Difference From Other Sport Earbuds Although the uses during exercise aspect of this wearable are probably more likely to be a selling point, the voice control features make the V-Powerbuds Pro an attractive alternative …
