They are compact come in their own case and lasts a long time on a single chargethe behindtheear hooks makes these perfect for running on the treadmill or and physical activity because it wont fall off

Another great feature that still amazes me is that they are ipx4 sweat prooffor the price these are a no brainer i recently picked up a pair of these bluetooth headphones as a gift for my wife

I was happy to see that these came with 3 different size ear buds because i do have smaller ears and have had a problem in the past with my headphones being uncomfortable and making my inner ear sore
