This is literally the biggest bluetooth headset I have seen in my life.The part that wraps around your ear doesn't rotate to adjust the angle of the headset, which makes it very uncomfortable if the earpice doesn't fit perfectly into your ear. It is attached using cheap flimsy plastic and a spring that will easily break.On that note, I thought that the earpiece was similar to that of a plantronics, with a rubber earpiece that goes into your ear. This is just a painfully hard plastic one.Button locations are very inconvenient and hard to press as well. The answer button is on the bottom when it's on your right ear and on the top when it's on your left making it confusing if you switch often. Similarly, the volume buttons are only in their logical places when the headset is on the left ear.Sound quality is terrible at high volumes and mediocre at best when low.Overall piece of junk. Very glad that I only paid $3 for it on a one-deal-per-day website.
