"Battery life is also good. ."
"Pros:Great wireless use,Good long lasting battery,Great bass,Very good sound quality,Bass Boost for occasional listening with double extra bass,Great comfort,Good quality. Con:Too big size so uncomfortable while moving head when it is kept around neck."
"The battery backup and wireless range of these headphone is really good too (20 hours, 10 meters). Go for it if you want good bass from your headphones and if you are not the purist type."
