Summary: My use is for home and small home office. If I was in large office and required constant use for 8 hours, this model will be a disappointment. But for home it is perfect. I have run through several other brands and settled on this model. Previous favorite is 3x the price.
Summary: i cant hear the caller very well even at the highest volume any noise close to you will drown the person on the line's voice. not recommended and cant be returned so don't bother get something better.
Pros: It's just a simple cordless phone headset but it's simple and has good volume. These type of headsets are becoming hard o find. I use it as a backup if my blutooth ear set needs charging. I work 10 hour days from home. Mostly on the phone with other IT companies. My Plantronics Explorer regularly...
Summary: I tested it on a Samsung cellphone -- I don't know if there was an impedance mismatch, but it was hard for person I called to hear, unless I yelled. But, if I yelled, they couldn't understand.
Pros: Fits fairly well, but since it's unusable, I didn't wear it long.
Cons: Microphone picks ups other speakers better than it picks up the actual user. Transmits a continuous hiss . . . and that's indoors. I can't imagine using it outside. It's essentially unusable. But since it's apparently just a really bad design, rather than being broken, I can't return it.
