Clarify if wonderful as long as your phone is near by. My dad could not use them. The sandal is really cute and decent quality for the price but I cannot give it 5 stars because of the issues with the size. My only problem with this headset is that my son now plays game longer now because its more comfortable and he cant hear me when I call him. I havent depleted the charging case power yet since my last charge, so I cant comment on how many hours one charge may last at this time. something else these shoes are coming from china well made the brand i ordered anyway but i must say they been compressed in a box yass i fluffed mine out with my hand but i saw on a review someone complaining they saw them and didnt take them out. Length and size is good, but the strap cant tighten enough to stop them slopping about. Ive bought several sets over the last 5yrs in case they were discontinued, glad I did! Ive been using both pairs for over a week and have had no problems! Espero que les sirva.
