Again they tick all the boxs that £100+ buds deliver! Heres what I did to make them fit:Remove the laces altogether: The neck wraps around the top of your ankle like a sports sock and Im confused why they included laces. they are not so comfortable because my feet hurts sometimes. Next update?Ill run with my phone tonight and report back on the viability of being running buds and quality of reception with a phone on your body. It was 10 out of 10 for ease of assembly. Good grief what n experience! Easy to put the frame together. Setup is easy. Tienen una gran bateria, da para 4-5 horas y en la caja cargándolos te vale para usarlos con 3 cargas completas. They are not your normal headphones and therefore will not be as good BUT they are far from average.
