Any preference between earplugs and earmuffs? I have a pair of 3M Peltor WS Alert XP. Earmuffs, bluetooth capable, has a boom microphone that folds up to the left, easy to answer with just a button on the same side as the mic, IIRC. Range of the bluetooth is...extensive. I think I had to move probably 15-20 meters from my phone, which was charging in a small concrete room too for the music to cut off. If there are no barriers, the range is a lot more than that. Pretty expensive though, I had to pay a the equivalent of $300 for mine. Battery life is about one week of work, using disposable batteries. Also, music pauses (I think, haven´t given it much thought when I answer calls on it) when you take a call.
