About this item

• 
  True Open Ear Headphones: PSIER headphones adopt a completely open
  design, the earbuds can be gently and firmly placed on the top of the
  ear. Open ear earbuds are typically lighter and more breathable than
  in-ear headphones, making them more comfortable to wear for extended
  periods of time. (Please clean the headphones after use to extend their
  lifespan)
• 
  Be Aware of Surrounding: Since open ear headphones don't go into your
  ears, they can make you more aware of your surroundings. When you listen
  to music while running or cycling outdoors, you can still hear
  approaching cars or other potential hazards and go through the day with
  safety.
• 
  40H Playtime & Digital Display: On single fully charge, bluetooth
  headphones last up to 20 hours, and the charging case can charge the
  earbuds an additional time, so you can get 40 hours of total playtime
  from a fully charged case. In addition, the smart LED Power Display in
  the case shows the remaining battery in real-time, which lets you know
  if the charging case or running headset needs to be charged or not.
  Don’t have to worry about any power issue.
