The hat is very nice by itself...Warn, nice looking and added the bluetooth headphone is pretty neat...I love the sound and the volume of these.
They are stereo speakers but if you are looking for something that you and all of your neighbors sitting next to you can hear with certain clarity then these are not for you...Easy to pair, connects fast. Does not loose connection unless the battery is dead.
The hat as well as the bluetooth sound is clear, not muffled or tunnel sound. Very good volume and actually sounds like one of those pill bluetooth speakers in your ear.
I love the sound on here,the comort and the feel of the hat and sound...Glad I got one..Overall fell of this iem is a 4 star, took off 1 star for whenr the controls are located.
I recomend this item to family and friends.
