UPDATE January 2024: Headset broke. Plastic cracked just above the earpiece. Very thin plastic. It was 10F that day. Purchased this August of 2022. It served me well.....RIP headset. Battery life was a amazing, no degraded battery life. Microphone has awesome noise cancelling. Windows open, doing 70mph and person on other end has no wind noise. They an hear crystal clear. Long range with Blue Tooth. No complaints other than the thin plastic. Am I going to buy again?? No........the plastic broke in the cold while putting the headset on.i am a mobile diesel/heavy equipment mechanic. A few years ago I bought some very expensive clip over the ear ( other earbuds seem to fall out of the ears when I'm working on equipment) earbuds. Those seem to pick up a mouse farting at 100 yds. Out in a slight breeze, the person on the other end of the phone swears I'm in a hurricane.........and forget trying to use the earbuds in the truck while driving!! My Peterbilt work truck has a built in microphone with Blue tooth.............the mic doesn't work so great. I need to be leaning over the steering wheel for the other person to hear me.Frustrated, I purchased this headset. Good price at the time, had some good reviews........figured what the hell........I'll give it a shot.NOW TO MEAT OF THIS REVIEW!!I bought this August 2022, it arrived, I charged it and threw it in the truck. Whenever I get in the truck, I turn this on and go about my day. When I get to my destination, I shut if off and leave it in the cab. While working on equipment, I don't put it on until I get a phone call (it's kind of awkward to wear and work on equipment). I haven't had to charge it yet!! It's been 2 months of almost daily use!!!Yesterday I was talking with a buddy of mine discussing the plans for the weekend. I was in the middle of changing out an air brake can while talking to him. I needed to use a 4 1/2 grinder to cut some steel. While cutting the steel, the mic was maybe 1 ft away from the grinder. He didn't hear ANY OF IT!! I had warned him to expect some loud noise. None of the noise was picked up by the mic!! (If you've cut some steel with a grinder........you know how noisy that is!!) I then needed to use a 1/2" air impact. I told him what I was doing..........he said unless I told him, he never would have guessed...........the faintest noise from the impact conveyed through the mic!! Again, that was 1-2ft away from the mic!!Overall its a great unit (I think). You have 3 controls on the speaker ...........VOLUME UP, POWER/ANSWER/ END CALL (middle button), VOLUME DOWN.........very simple, easy to use, comfortable. The mic has a RED LED light that lights up when your talking on the phone...........useful when you have people walking up to you and they might not realize your on the phone. The volume and sound are good. With the window open on the truck and going 70mph I can hear people and they can hear me.I was just totally impressed yesterday after using the grinder and NO NOISE was conveyed through the mic.......had to share that.
