Battery is awesome so far. They charged at a fast pace, and each device you have on the charger, shows a green indicator light letting you know you are connected and charging for each separate device. I have the JBL Live 400BT and this case fits perfectly. UnboxingThe "G2 Bluetooth Wireless Headset" comes with a nice litle travel storage case, two silicone in ear adaptors, instruction manual, waranty card and the G2 bluetooth headset. The volume up button stopped working on my xb950bt less than a year after I bought them and the track switch button was pretty finicky after two years. Definitely recommend ordering a half size up from your standard sizing, but otherwise they fit great! So, I would say the sizing runs a tad small but I get confused with all the different sizing. Great flavor for an energy drink/pre-workout drink, and they are strong in the caffeine department. Thinking that this was strictly related to my desktop, I moved over to my laptop which only has built-in speakers. Ive put a lot of miles on them because music is my medicine and the sound quality JBL puts out is my favorite.
