Pros: Noise cancelling works, lightweight, reliable
Cons: Larger than some, weak output volume, wind causes issues
The Aliph Jawbone is the original effective noise-cancelling Bluetooth headset, and it worked wonders. As a frequent traveller, I found this headset gave me freedom to speak with people in environments where I could not previously. Airport gate areas, concourses, and noisy vehicles all became places where I could make a call and have a conversation.
However, the output volume from the headset isn't very loud. Comments to Aliph customer service led to them "educating" me about the dangers of too much volume that close to the ear instead of a real resolution to the issue. As a result of the low volume, I often cup my hand over the headset to hear in noisy environments.
Wind is an issue with this headset, as well, making the user largely unintelligible at the other end.
