I speak approx. 5000 minutes a month on the cell phone. For one reason or another the bluetooths have not been conistent enough for me. They always seem to falter at critical times and I have tried at least a dozen of them.
After finally going with the wired ones and I have tried literally 25 to 30 of these wired headsets and the average cost of them was about $20 - $22. I use them mostly when I am driving, but they always seem wanting in one way or another. There never seems to be enough volume on them. Finally this one makes it. It works great and the volume level is more than adequate - Horray!
If you are looking for a reliable excellent headset and not want to burn your ear with just using the phone earpiece, this is the one to get. I am actually ordering another one today! (Posted on 2/4/13)

I use this for voip calls from my laptop on the road. the "boom" with "ear"piece hangs over top of the screen. very compact and portable unit. 3.5mm adapter is a nice add-on for max flexibility.. (Posted on 1/30/13)

Push to talk function didn't work. Mic always on. (Posted on 1/30/13)

For the price, you can't beat. I am very pleased with the quality and the comfort. (Posted on 1/30/13)

This is the only headset that actually stays in place in my ear. I have purchased many of them and would highly recommend this product. (Posted on 1/14/13)

I use this with my cordless phone happily (Posted on 1/14/13)

The connector does not fit my iPhone and home phone (Posted on 1/9/13)

Don't buy this, it's cheap in price but very poor sound quality and the other caller have a hard time of hearing what you say. (Posted on 12/29/12)

I have been using Plantronics headsets for many years. They have all been *awesome* - the best sound quality and great durability. You must be sure to purchase the right product, however. [...] I wish other people who review products would be more careful. The Plantronics website quickly checks compatibility for you - a few extra seconds well spent. Also, if you are not satisfied with *any* product, most manufacturers appreciate the feedback and will help. They want satisfied customers. (Posted on 12/27/12)

I received this fairly quickly. Butphone quality is so poor it is unusable. (Posted on 12/27/12)

Poor call quality (Posted on 12/27/12)

Does not fit properly on a iPhone or my land phone. (Posted on 12/27/12)

I work in the health care field and have to travel many miles every day to see my patients. Communication via cell phone is critical and I carry more than one brand of phone. I am very pleased with the quality and comfort of this headset and recommend it. (Posted on 12/26/12)

Excellent sound quality. Noise cancellation really works. The button on the headset string lets you automatically place a call and end the call. Very nice. Works much better and more reliably than ANY BlueTooth set I've tried - and I've tried almost all of them. (Posted on 12/26/12)

This is one of the best hands free-wired devices that I have had. Great price. Would most likely buy another when this finaly stops working. That is one of the issues with wired devices, they eventually stop working because of a broken wire. (Posted on 12/16/12)
