I am a runner, stay in ear perfectly, however, although very loud, its not a good loud. absolut traurig . I think the sound quality is good, nothing to blow me out of this world but enough to where I dont hear others in the room or nearby. This is an exceptional value for the price. These are a high quality sandal. These are just as beautiful as most of the companys other headphones so there shouldn?t be concerns wondering if you will look like a dufus walking down the street or even on mass transit. I took a chance and bought the 6mm and Im glad I did. Dec 8, 2020. Buen precio, a pesar de que la tela es delgada. The projection was NOT visible in any of the pictures!
