One of the best Bluetooth headset for mobile phones is Aliph Jawbone and the second generation of the headset has made an appearance via the FCC. The Jawbone 2 is slimmer, but it will retain the “Noise Shield” and “Voice Activity Sensor”, two features that made the original Jawbone an excellent headset. Aliph has also decreased the size of the charging cable and the charger itself. The headset will still come with an earloop and various sizes of earbuds for better fitting.  Overall the Jawbone design hasn’t changed much and that’s a very good thing.
