I bought the older generation Jawbone for economy's sake and it's not a bad headset. Although a bit larger and heavier than the latest model, I found that by selecting the right size earpiece from those provided (there aren't a lot but enough) I can wear it without using the over-the-ear hook. It's just more convenient for a quick on and off. The "hidden" buttons are a nice feature and not difficult to use once you know where to press but the rear button that resides under the charging plug is a little too flexible for my taste and it tries to separate a bit from the headset when the plug is removed. I'm hoping that isn't going to be a problem after frequent use. This is the third bluetooth headset I have tried and seems like a keeper. The product category is a tough nut for internet sales because so many out there are repacks. You will note from other reviews that people tend to try many headsets before they settle on one that functions and fits to their liking. Consequently, a lot of them are returned. Beware of any packaging that is not obviously pristine and factory sealed. You might have received someone else's cast-off and parts could be missing.Update: After several months of use, the process of unplugging from the charge cord got tougher and tougher. Finally, the thing fell to pieces in my hand.
