I own two of these headsets and have not experienced any of the issues that the other reviewers have commented on (I have had them over 3 years). No one has ever had any complaints about hearing me (unlike my parent's feeble attempts with smaller earbud type headsets) and I have never experienced the buzzing that others complained about. With the 2.5 mm jack, it works in both my cell phone and my cordless landline, which is a huge plus when trying to talking on the phone and get chores done.Now, be warned, you will look like you work the local drive thru joint. Be prepared for the plethora of "would you like fries with that?" comments that will inevitably come, but remind Suzy Sarcastic that when she calls you on your cell, you never have to play the "can you hear me now" game.Bottom line, the best quality sometimes does not come in small packages. I highly recommend it.
