Bests & Worsts Reviews from Amazon

I bought this for my wife who works from home for an employer in another state. She is a data analyst who teleconferences for HOURS every day. Her previous bluetooth headset was an LG model that had an obnoxious tinny sound quality to it and occasional lags or skips in the sound. I hated it. Every time I called her, it sounded like she was talking to me through a piece of aluminum drainage tubing, so I always made her take off her headset and talk into the phone. I finally mentioned that her employer was probably annoyed as well, and she mentioned that they did often ask her to repeat her comments during meetings. A few months ago, I bought her the Plantronics M55 headset as a gift. At first, she said I shouldn't have spent the money and her old one was "fine," but as soon as she tried it, she was amazed. She could hear others better, and suddenly there were no more requests to repeat herself during meetings. Frankly, when I call her I can't even tell she's on a headset. She sounds crystal clear and right next to the phone. No more of that obnoxious tinny and hollow sound that the other headset had (and that most speakerphones seem to have as well). When I mentioned that Amazon was asking me to review our purchase, she summed it up this way: "Absolutely fantastic. Worth every penny. I love it." Enough said.
