Used it 5-10 hours a day (mostly work). Ich hebe mal auf 3 Sterne an, weil der Kleine immerhin fast alltagstauflich ist. I finally got an ebike and life is great again. I havent had any problems with it yet, but on an old pair of Tours, they did go out eventually, but hopefully thats not going to happen anytime soon with these. The battery life is absolutely amazing, as I can easily get close to ten hours on a single charge. Very useful for me b/c the ancient elliptical trainer squeaks so much. First off I want to say that I really like the Fusion Beats Bluetooth Headphones. The sound and ease of use are great for these buds. As for size and half, thats your call. But these are different story altogether1.
