No wired earpiece is ideal but I refuse to have a bluetooth for health reasons. This headset is by far the best sounding I've ever used-and that's from the caller's end as well as the user's. I've been by the caller that they can't tall at all that I'm on a headset and while I'm accustomed to have to keep trying to turn my volume up with other headsets, with this one, I keep my phone volume on almost the lowest setting, even in noisy areas. They included several adapters of different sizes as well as a side-specific design-meaning that the earpice that goes in your ear on the left side won't really fit if you try to put it in your right ear. Maybe this would be a negative for some but for me, anything that allows me to have my call made without the interuption of a falling earpiece is a good thing and I'm not one who switches from one ear to the other. I do recommend trying the different ear piece cups to be sure that the one your using is the right side & size since there are no instructions.Considering what I've paid for far lesser, these are in a different category all together. No instructions but if you log on here, I'm sure you can figure them out...
