Summary: This head set was a big disappointment. It does not fit into my ear properly. The person you are talking to you can hear just fine but I can hardly hear them. The volume increased on the phone does not make any difference. Either way I use it, I can't hear. It falls off your ear also. I am trying another one and then ordered one just specific for the phone.
Summary: plantronics makes great products, and this is no exception. great sound quality and your voice transmits smoothly. cannot go wrong with this item. great for everyday use at the office or at home with a cordless phone.... moblity as you need it.
Summary: Yes, we wish we had been wiser and not purchased another one. But we did. Familiarity, availability, a bigger discount... The first one lasted about seven months. The second one not quite six weeks. Same problem, no sound. Both units were never abused, including that we never tried using them in a lightening storm.
Summary: This headset is my favorite. I've used them for years and they wear out from use, which is to be expected. I hope they keep producing it. If the headband is too tight for you, just bend it a little. It also comes with an ear loop. Great incoming and outgoing volume controls.
Summary: Humming noise with ATT 17939 phone. I ordered the Panasonic KX-TCA430, it worked fine with the phone. Plantronic has better build quality but I got tired of humming noise on my daily 1 hour meeting. It gets louder if you increase the mic volume. When muted, the noise goes away.
Summary: There seems to be some conflicting information about using this headset with the iPhone among the existing reviews. For the record, the jack on this headset is not the right size for use with the iPhone 4.
Summary: Aftern pointing out my disappointment in their packaging, OEM contacted me and explained their approach and provided a small credit against my purchase. This is good customer service -- OEM will get my business again.
Summary: I bought this because I work from home and participate in conference calls most of the day. The audio of the headset was great, but less than a month later the headset broke (the plastic holding the "band" of metal that goes around your head cracked) and now I can't use it anymore.\ Update December 2011- So I contacted Plantronics about the headset breaking, and they sent me a new headset, no questions asked.
