Does what its suppose to.The range is better then advertised.
This earphone is very comfortable and the quality of sound is super good.
I was not completely happy with the condition of the item and the seller was super responsive over email. Shipped me a replacement at their cost.
The Bluetooth Ear set connected to my computer and may phone at the same time, no more plug-in plug out. You can talk for a long period of time between charge (I did 6 hours) Charge fast during your lunchbreak The app that you install on your phone took care of the earpiece software update automatically
