What's UP with all the BAD REVIEWS??????I bought this headset over a year ago so it's strange coming back to finally write a positive review only to see all of the negative reviews that have been left since then. Product issue or a user issue? Probably the latter.I go through headsets like they're going out of style.....not because I have to have the new next best thing but because I am a little irresponsible and impatient.......I forget to take them off while jumping out of my seat which breaks the cord, I set them on the floor by my bed at night before going to sleep......only to wake up and step on them. Friends come over and don't see me attached to the t.v. and walk right into the cord ripping it out breaking the connector.....etc.This is close to my 30th headset in 7 years and I have to say......I love them. My wife accidentally broke my last set a month back because I didn't put it away properly so I just went ahead and reordered another set 5 minutes ago which made me think to leave this review.It seems like most of the bad reviews are due to popping and hissing sounds along with "big ear", "big head" discomfort and recorded background noise (which isn't a big issue if you have a good recording software). There's nothing I can say to help with the "big ear", "big head" discomfort.....I have relatively small ears in comparison to some of my dumbo eared friends so the set fits me perfectly and I don't have an overly large head so they do not feel like they are trying to "squeeze" the grey matter out of my noggin.I can however comment a bit on the hissing and popping sounds and the recorded background noise.......so here we go:If you are running either Windows Vista or Windows 7 64 bit version then there is a patch/update you will need to download and install that will completely eliminate the hissing and popping noises. The patch/update has nothing to do with Plantronics as the issue effects a ton of other audio recording/listening devices.....not just this one. I had the same issue when I first bought my headset, but unlike many others MY first thought wasn't that the product was defective but rather that Windows 7 64 bit had an audio driver issue......which is exactly the case. Ask questions first, shoot last.Keep in mind that this happened over a year ago so I have no idea where I downloaded the patch/update, however, I could have only got it from one of two places which are either on the Microsoft site itself or it may have been an audio driver update for my Nvidia sound card. If it was the audio driver update then you would need to find out what sound card you are using and then go to the manufacturers website to see if they have an updated version for you to install. Most manufacturer sites nowadays have a "scan" feature that will scan your pc to detect what model of sound card you have which will then give you a link to your update when finished scanning.Once I had installed the patch/update I restarted my laptop and voila! All of the hissing and popping magically went away and I was blessed with absolute silence and superb audio clarity.Best Headset I have Ever Owned for the Price!!!! and I do say that from first hand experience. I even returned my Sennheiser RS 180 Digital Wireless Headphone System that I purchased on January 25th 2012 from Amazon due to the fact that the audio quality of the Plantonics was comparable to a headset that cost 10 X more AND I could use the headset to record audio which I couldn't do with my Sennheiser. Do I miss the walk around the house, never trip over a cord again $300 headset with charging station? A little.....but not enough to get them again.As far as the microphone goes......is it sensitive as all heck? You bet. Is that a bad thing? Not in the least.1. First thing, is don't have the mic right next to your mouth otherwise you will hear your monstrous breath hitting the mic and you will even hear your your lips macking as you talk. I always put the mic about 2 inches up from my mouth.2. Second thing is the background noise.......the mic picks up EVERYTHING so you either need to be in a soundproof room while recording........or.......you need to purchase a recording software that enables you do get rid of the background noise post production. I personally chose the software route because a soundproof room just isn't an option for me. I use Camtasia Recording Studio for all of my audio and video recording because I do a lot of online video tutorials so this works perfectly for me. The background noise cancellation feature is absolutely amazing.......and I live on one of the NOISIEST streets in Waikiki, Hawaii where when the buses go by they sound like they are quite literally driving through my living room.My experience with this headset has been nothing but all A pluses as has my experience with most electronic I have bought here on Amazon.....or anywhere for that matter. Keep in mind, the average pc user hasn't the foggiest of what they are really doing once they go beyond sending out emails or web browsing. They expect to "Plug and Play" without knowing how to properly troubleshoot or to even read the manual for compatibility issues. Most of the "Bad Reviews" left for ANY electronic device or product have nothing to do with the product itself and have EVERYTHING to do with the reviewer's own ineptitude. No offense meant, but that's a fact that I see all too often in my line of business.Definitely a good buy if you are able to troubleshoot and problem solve. If not, then this won't be the only headset you'll leave a bad review for.
