and I wear a size 15 and these fit perfect. While in Bluetooth mode,the built in mic is not the same that goes in front of the face, so it picks up less of the direct voice, but still has decent quality (especially compared o other Bluetooth mics I tried) When the audio line is plugged in, the Bluetooth automatically turns off, and the so the audio switches right back to plugged mode, which is convenient and a nice touch. En una habitación tranquila se disfrutan y mucho, pero en una zona con mucho ruido exterior como una oficina o la calle puede ser un problema. Red and blue are clearly a no go lol. The medal is very sturdy, and the wood top is beautiful. If your not great at improvising or good at putting things together, consider another product. It cannot be done. I run the Wii through an external set of speakers so the audio component was not important- all I needed was to have dual video inputs and this does the job. Its the same concept as rubber feet on a keyboard: the dustier they get, the less grippy they will be. I like that they can be machine washed.
