Review on 🎧 Plantronics 211855-99 BackBeat Fit 3100 True Wireless Earbuds: Sweatproof & Waterproof In-Ear Workout Headphones, Black-One Size Fits All! by Robert Toomey

I really wanted to like these headphones. I had old backbeat fits and they were great, but sometimes the cable irritated me so I figured they were perfect. I wanted to use them for cross country skiing but they just don't work in the cold. At best, I get 1.5 hours of battery life in the cold, but sometimes that's not even there. Even in the heat, the battery life is well below the specified 5 hours. I don't think I've ever gotten more than 2.5 hours. Pros * Good fit * Good sound quality Cons * Mostly doesn't work in cold weather. * Mediocre battery life even when warm. * The charging case does not always charge when needed. The light won't come on, so you have to plug it in and hope.
