mikeyThis is true, that's only when it's connected to the phone though. It doesn't do this through other devices, but when the phone is about to receive a message, or you've just paused a song etc, there's a frequency ring about 14k which is faintly there, sounds like a hearing test a bit. But if you've got the music playing or anything else going on it's clean, it's when it's in a standby mode and about to receive data that the problem show s up.
mikeyIn a noisy environment there are already so many sounds at those frequencies that you wouldn't hear them no matter how hard you tried, or how sensitive your ears are. It's almost in audible anyway, not to mention most people can't hear frequencies over 13k anyway, as time goes by people's hearing (especially someone working with heavy equipment such as yourself) deteriorates, those saws etc I can assure you have damaged your hearing causing you to lose sensitivity, heck, maybe even complete ability to interpret those frequencies all together.Hmm, guess my ears are not that sensitive - I've not noticed this yet.
I can say I'm quite impressed with how long it lasts on a full charge. I've made three - 2-1/2 hour train trips with mine all on one charge - still pumping out great! It's so nice not to contend with the wires! I see dozens and dozens of users on the train with the wires hanging all over the place and at each siting congratulate myself for grabbing a pair while they were on sale for the twenty five bucks!
