Pros:Price of this unit on Amazon.SOund qualitylight weightBattery lifefolds to almost half its extended sizeCons:-volume buttons need some redesign. I have huge fingers and still cant get used to doing the volume without looking at the buttons on the right ear phone.-no noise cancelling feature in this model. couldnt be that much harder to add it. im sure later models will have this feature.-BT connection problems. Not sure if its the headphones or my LG Voyager, but sometimes even though the LG says the Sony headset is connected, music will come blaring out of the phone instead. It takes some power cycling of Bluetooth on the phone and headset to get everything to work. Again, this may be LG Voyager issue.-Travel pouch sucks. Absolutely no padding.
