So as far as the recording quality compared to the top of the line mics, I have no idea. Mi consejo es que si compruebas que están pegados por la parte trasera se los devuelvas, y que se los coman con patatas. Fue un regalo y le encantó. I downloaded the app for these key finder and it works then it stops working the next day. Speaking of ANC, it might as well not exist. Has this happened to anyone else. The shoe box inside the mailing envelope was ripped and totally destroyed. I have used them to carry larger ladders, sheets of plywood, construction materials and all sorts of longer items that wouldnt fit into the car. Phone: 5 stars- Calls come in quickly. I got some stickers from the dollar store to cover the holes and am very pleased with the finished look!
