Product review (5 stars): I love this Bluetooth headset
I love this Bluetooth headset, since it has good sound quality and is easy for me to use. Pairing is simple:  I turned on Bluetooth on my Windows 10 and then you hold the big QCY button that turns the device on and listen for on and continue to hold and you will then hear pairing so you know that it is pairing.
Sound quality is very good and earbuds are very comfortable and have assorted sizes.  It is no problem to remember the controls, since the main button is in the middle of the right earbud.  USB flap is very small but easy to open as long as you remember to use your fingernails, then it opens right up.
