Light-weight. The other foot was really tight. They are build to last and the sound quality is simply amazing. An added factor is that he has a wide feet and a high instep. They fit like a dream. I got two of these, one for me and one for my granddaughter. My little boy just turned 1 earlier this month. The sound was very good . This may be the most vivacious and lively shes ever been onscreen. I have tried a number of different wireless earbuds to use with my Android device and laptop.
