So I can put these in my ear and shake my head around and they stay put and feel secure. Then, randomly, later on I can be just standing and talking to someone, with little to no head movement and an earpiece can just POP out striking the concrete or tile and ricochet under the sink into the floor drain, for example. The ambient hearing setting is pretty cool, it almost works. I mean it DOES work, but it's not the same as having nothing in your ears, it's more like having only a partially effective plug in your ear. I could still hear people speaking to me, but they were muffled and harder to hear than normal. Distance sounds were much harder to hear than nearby sounds. On noise reduction mode it worked like a normal earbud and reduced outside noise. These have been the best at phone calls that I have tried lately. They quit making the bcs700 neckband which worked great for phone calls (well, worked okay, which is better than most), so I've been experimenting with all kinds of replacement ideas. These little inside the ear earbuds are comfortable, the volume is great, the caller can hear me over the background noise around me.. which is something 99% of these things fail to achieve. They're small and their case is small, so it's not as inconvenient to take them out and put them in my shirt pocket or their case if I need to talk to someone without my ears plugged. They're tough, I guess, because one of them has hit the concrete twice, the tile once, and they other hit the tile once, and so far after 1 day they haven't shattered. That's going to be a problem though. I can't have them randomly POP-ing out of my ear to go skittering off under cabinets or whatever, especially not on construction sites where I work. They'll end up in wet cement, or down a floor drain, or buried in sawdust or something one of these times. The good: comfortable, lightweight, long-lasting (8 hrs or more), good volume, almost let's you hear ambient noises when set to that function. plus they have a cool app! The best part of the whole thing is that your caller can hear you, even in a noisy work van with tools and equipment rattling. Even with the AC on and blowing at your face. Even on a jobsite where various people are running power tools in the background. That's Fracking amazing. The bad: I never could figure out where the "button" is or what makes it think there has been a press or double press. Somewhere on this little bud is a "button" that does different functions depending on if I press, double press, or long press. I assumed it would be the big flat round piece with the logo on it, but there's nothing that gives you a tactile feedback and the device doesn't always react if I press there. sometimes it does, but sometimes it reacts as if I pressed there when I'm touching only the edge.. so I'm not sure. I'm sure it says in the manual, but I'm sure I can figure this out on my own eventually without having to resort to reading the manual!! I'm not a nerd!!! Another bad thing: They randomly POP out of your ear, especially if you happen to be over tile or concrete. If you carry a flashlight in your tool bag, that can help you spot them if they end up in a floor drain or wedged in the dark recesses of a bottle caps, broken glass, in a sticky black patch of goo that was probably formed from old beer and soda, under the sink at the bar where you are working. These might be more suited to a carpeted environment so they take less impact damage. I kind of wish I had bought some with an ear-hook so that if the bud part popped out at least it wouldn't fall to the ground. I'm going to try these another day or two, try some different eartips and see if I can reduce the POPout.
