En general lo recomiendo, vale la pena la inversión. )Anyway, the one-sstar review is because of Logitechs horrid warranty handling. Get them while they last. These were way too small - at least a size off. I love these as they can get wet with no damage and they are nice and cool to wear in the warm weather. Very stiff The Bad:-Unresolvable Bluetooth issues-Microphone is at best mid range-No mute button, raising and lowering the boom arm is not as functional as you would imagine. Weather here is turning cold, I needed something I could wear that worked for a change. I like these very much. I would give this unit a higher rating except the issues with the Motherboard and the NZXT software did not want to play nice together.
