As usual with Amazon, the headset was delivered quickly. Unwrapped, Bluetooth is turned on and the tablet headset, whoosh: Both were connected and could hear music immediately. Headset applied. Super. Fit All. That somehow sat loose! No. Likewise, I had imagined. Sound is full for such a small headphone zufriedenstellend.Super also is: no handling of batteries. Simply connected to a USB power source and is indicated by a warning light when the charging is completed. Could not be better.
