I have now been using this microphone for a week for my work conferences that I lead, all clients have commented on how clear my sound is projected onto their computers. QUALITYThese are great headphones! My only complaint is that after one wear, the surface of the shoe foot bed started peeling off in two places. I got them in womans size 11. Battery life could be a little better, but at 1/4 the price of the Beats, they are a great choice. 5 in New Balance and Under Armor. Después de una semana con ellas estoy muy contento. Like this brand very much. These slippers do not flip flop like slides. Only reason I bought was to connect my iPhone/ iPad to apt-x enabled devices (Bluetooth receiver, LS50W).
