  • Great Headset overall. I purchased these to wear when I am working in the shop around my cnc mill and piston air compressor and when out driving the tractor. I looked at the cheap home depot ones and many others on amazon and was concerned about their quality. I have a set of Peltor headsets for shooting and they are so tight that they give me a headache after a few hours of wearing them. No headaches yet with the David Clarks and still excellent hearing protection. They are so good I can keep the bluetooth volume at less then half and the audio is loud and clear. I wish these had a option where I could use these instead of the peltors for shooting. Basically use the mic to hear conversation with whoever Im talking with on the line, but then turn off the mic as soon as shots are fired. Just like any other shooting headsets. I dont think the headset has the aptX for better quality audio streaming but could be wrong. I do wish I got a little bit of mic input audio when talking on the phone to someone played over the ear speakers, cause I end up almost shouting not being able to hear myself so well when talking to control my voice level. Work nice under a hardhat though they do cause the hardhat to ride just slightly high but still very manageable. To Marv Golden's sales/shipping teams credit, I ordered these on a Wednesday and needed them Friday to use over the weekend. Since the DC factory is back in Mass and they drop ship, there was a concern that a 2 day shipping would not make it until Monday or Tuesday. MG upgraded the shipping at their cost to over night and made sure the headset arrived before the weekend.
  • Pros: No Headaches from being over tight, good noise reduction, great battery life.
  • Cons: There is a little bit of clicking noise when BT is switching to the next track, or connecting and disconnecting for phone calls.
