The battery charge lasts for hours and he just pops them in the base when he goes to bed and theyre fully charges the next morning. These are not only super adorable but They are truly comfortable! The reason?s a lot more comfortable to have the ear pads resting on your collar bone than the hard plastic covers of the opposite side. Where the sound fails for me is in the highs. It now hangs in barn so we always know where to find our jackets. I?m a size 4/6. This dress had surprisingly good-quality fabric for the price, and was assembled well. I couldnt believe how comfortable they were wearing them all day in the water. Out of the box great sound and easy to mate to my iPhone. I personally didnt enjoy the amount of focus they had on the bass, but generally, it gives a nice warm tone to what youre listening to and provides a good amount of volume.
