With the new Era, Jawbone continues to produce quality Bluetooth headsets that you'll want to take calls on. The sound quality is top notch, with Computerworld saying they're "most impressed" with the Era, and that "for such a compact device, the audio was clear and quite audible." The microphone is good as well, with Re/code noting that the people they called had "had no trouble" hearing them and incoming callers sounded "clear." In addition to sounding good the Era also feels good, with Slashgear being able to wear it all day "without any discomfort." Even though the battery life comes in at about only four hours, the updated Jawbone Era should be at the top of your list if you're in the market for a new Bluetooth headset.
