• The battery is less than stated, it lasts around 2,5–3,5 hours on a single charge in my experience.
• Like all devices, it will always connect to a previously connected device when you activate them. They can pair with two devices, but not two devices at the same time.
• It has a small touch button.
• No, no further accessoires for the fit in your ear, just different sized eartips.

Hope this helps :-)
