Since you are taking these headphones into the pool or open water, plugging them in mid-swim is not an option, so finding a device with great battery life is important. Our writers and editors thoughtfully select experts to collaborate on product recommendations, and they are experts in their own right, using their informed opinions to select products and ensure that our content is of the highest quality. Our product recommendations are purely editorial, and while we may receive free products to test and review, we only recommend the products we are most impressed by.
