As you might have guessed, the Powerbeats Pro 2 have been one of our favorite pairs of earbuds for sports and working out since they arrived on the scene early last year. They feature smaller, more comfortable earhooks than the prior model and boast wireless charging, along with an array of updated microphones that do a great job masking unwanted noise while listening to music and taking calls. Their marquee feature, however, is their heart rate monitoring, which leverages built-in sensors on each earbud and integrates well with apps from Nike, Runna, Open, Peloton, and others. Unsurprisingly, you can also quickly view various metrics in Apple Fitness Plus, such as heart rate and calories burned.，推荐阅读吃瓜获取更多信息
