原文：For upright sports or mobile, these are very good. Like other ear buds, when laying down, the sound level drops by at least 3dB. When this happens, the bass also drops precipitously. Thus far, the only way to have it vertical and horizontal is to use headphones. If comfort is a factor, these are not
a solution. Still, very good. Battery life is good (5-6 hours continuous) but better than many others. Too bad. Longer life to around 10 hours would be ideal.

译文：非常适合运动时使用，和其他耳塞一样，只要躺下，耳机声音就会下降至少3个分贝，这时候低音也会陡然下降，你只能戴上双耳式耳机才能解决这个问题。如果你要把舒适度纳入考虑范围，那我想戴双耳式耳机也不是最佳办法。不过总体来说呢还是蛮不错的。电池续航能力很强，能维持五六个小时左右，比其他牌子的蓝牙耳机强出很多倍了。不过要是能够续航个10小时那就好了。
