"Battery backup very poor yet in standby mode"
"The battery backup is nice and bluetooth quality is amazing. Lot of sound comes out when you hear any song at high volume and the bass quality ofcourse is not that powerfull as the headphone looks like."
"Good sound but poor battery life . Sound quality is good, blocks out external noise."
"Worth buying and good battery backup as well sound quality is not bad as well. my over all experience with this product is good."
"Sound quality and best of all battery life. added and calculated the battery life 3 times."
"Only problem is there is no battery level indicator, so uI will have to guess it."
"Battery life is also very nice."
