Bests & Worsts Reviews from Amazon

I used the old 'three hump' Jawbone ERA for years. In fact, it was the only piece of my personal technology inventory that didn't turn over in 3 years! The thing was bullet proof. Decent sound. Decent battery life. I purchased the new ERA last month directly from Jawbone. It was quite exciting as they had almost 3 years to perfect their old ERA that I currently owned. But they didn't. There are a lot of reviews on this already, so I'll cut to the chase. There are two showstopper issues: o The battery life, at best, is three hours. It is less than ⅓ of that of my iPhone. Really? The thing is so small that they could have made it a bit bigger and stuffed in some decent battery life! 3 hours just doesn't cut it. I shouldn't have to worry about the battery life on my bluetooth headset amongst everything else's battery life. o Inbound callers CONSISTENTLY complain that they can't hear me well. When I call them back, they hear me loud and clear. Nothing else changes, my location, my phone remain the same. My other/older BT headsets work fine. There is a software/firmware bug. I really, really, really wanted to like this thing. My old ERA was a brute and just performed well. I had hoped that this did the same...but it didn't. I returned the new ERA and got a replacement and the same problem exists where inbound callers can't hear me well. It wasn't limited to my one headset; it appears to be systematic. My recommendation. Don't purchase this product. An addendum: June 24 2014. Jawbone released a new firmware version a few weeks ago. It does fix many of the quality problems to a partial extent, but not all. It also introduces some issues, such as voice 'pixilation' on calls, white noise during quite conversations, and it seems to reset the ringer volume on the iPhone when the Era device is turned on...strange. Once again, my old '3 hump' jawbone sounds and performs better than this latest release ERA with the latest firmware. Many of the issues probably have to do with physical design; something a firmware update can't compensate for completely. The device is very, very small. Making it difficult for it to connect with the cheek well so that the 'noise assassin' can do its job. So, my recommendation (if one can call it that) remains: Don't purchase this product.
