No issues with it so far. Simple, easy pairing with two phones, works well with both of them. Audio quality is decent on both ends of the call, and while it does pick up a little background noise, it's certainly better than many I have tried. My job has me frequently driving and using the phone, and my local area has a "hands-free" ordinance, which is a class one offense. You can be pulled over for having a phone in your hand. I depend on my headsets to keep me in contact with my office, my clients, and on the good side of the folks in blue. I currently have it paired with a Samsung G3 and an S7 Edge, and thus far, it has performed very well. One of the nice things about it, the volume can be turned up quite loud, if you find yourself in an area with a lot of background noise. This is probably one of the best headsets you will find at this price point. I have used a great number of headsets from bigger names (that cost a lot more), and they have all ended up breaking, coming apart, or stopped working. At less than $20, it's not a catastrophe if it fails...and it's inexpensive enough that it would not be unreasonable to buy 2 if it's a critical application. Talk time averages about 6 hours, and it's pretty quick to recharge. I do have a second one in reserve for those times.
