The delivery impressed: Six Essays should be suitable for almost any ear shape. There is also a behind-the-ear brackets for the event that the headset does not hold its own.
It fits comfortably in the ear and is so light and comfortable that you can wear it for hours. Loaded it is microUSB, so that almost any power input and each PC is suitable.
The service is a bit strange because the device (in addition to the mechanical on / off switch) has only one button. You can change the key assignment rudimentary (just like the speech), but you need a PC. It is also necessary to have an application on the Jawbone website and always have an Internet connection necessary because the configuration in the browser on the Jawbone website takes place which to communicate with an additional plugin to be installed on the PC.
To name positive would be the fact that the headset with two phones can be a truly hands simultaneously. Interestingly enough, my phone (iPhone 4S) indicates the battery level of the headset in the display next to the Bluetooth symbol, although this feature is offered by the manufacturer only under Android.
We come to the main point of criticism: The supposedly good audio quality.
Jawbone writes on his website, "Whether you find yourself in a noisy airport or on the road are your voice will always sound crystal clear." - That's not true, unfortunately. In addition, one should "be able to hear HD Audio" and "music, videos and calls" are purportedly have "never been better consulted". That's a very bold advertising lie. I own an iPhone 4s. But the simple, included headset sounds much better than the Jawbone. Both in terms of media playback and language, as well as understand what the called party.
The noise reduction of the Jawbone reduces noise actually from something. She buys but so that the called party of the voice also only sees a dull mush. It sounds as if you speak through a pipe, in which one has stuffed a sock. And the noise is loud enough, they also come through again.
In addition, the sound in the earpiece is not to be called HD. The headset overdriven strongly in loud passages, does not have bass and little treble. Music you want to hear so actually.
An interesting side note: If you use the headset to listen to the headphones, for example music, the sound is still reasonably passable. Then enters a call, it switches apparently to another mode. It begins noticeably to rustle, the quality is deteriorating rapidly. It is as if the bit rate coincides at a time to a quarter. Would use for voice calls the same mode as when listening to music, would be the transmission quality quite OK. But it sounds really not good. This could be due to the ear adapters. Unfortunately, there is no real in-ear adapters, so that the ear canal is never sealed to 100%.
Of course, the quality of transmission is also related to the power quality of the mobile service provider and with the phone. But in my case (iPhone 4S and O2 Simcard 4 out of 5 "bar" network strength) I believe it is insufficient.
Conclusion:
The headset is comfortable to wear and has a good delivery with the many ear adapters. The pairing and reconnection function well and even my two phones simultaneously. Unfortunately, it does not meet the high standards of sound and voice quality, the Jawbone, it advertises. "True" In Ear adapter could the fix that does not exist unfortunately. In addition, the noise reduction works not as perfect as advertised and each called party has previously complained about poor voice quality. Every (!) Cable-bound standard headset is this one superior to the reproduction of speech and music and almost every well in voice quality. I am very disappointed, especially because I had already in 2008 the first version of Jawbone (then there was only one model) and has since changed neither on the speech and audio quality even at the noise suppression noticeably something.
