This is one of those things that you dont realize you need until you have it. It rained overnight at our first stop and then we drove through driving rain for about 3 hours. I ordered these for the gym because I like the idea of having blue tooth headphones without having to pay over $100 for something like Beats. They were delivered 4 days before they were stated to arrive, brilliant! This wall mount was perfect! Hoping that these will last just as long ?? If you dont wash them, youll stink! This seems to be mainly because the microphone boom is too short(?), so the microphone tip is too far away from my mouth to completely pick up my voice. No fading or tangling. 36vHaciendo un cálculo, (16/3400)*1000=4,7ns, respecto a otro, (14/3200)*1000=4.
