  • I'm a generator mechanic for the Army, so I'm working on loud equipment all the time. I'm also a ham radio operator and a computer nerd.

    I took one star off for the audio quality. After work I like to listen to music such as techno, trance, dubstep, and classical. I do notice a difference in audio quality compared to my $75 sony wired headphones. The bluetooth also blips randomly due to interference. If you are an audiophile, you will have to look at something else. I'm grabbing Direct Sound EX-29 (NRR 29db) headphones to fill that role, but note, you can't fairly compare a wireless work headset to wired studio headphones (The EXW-37 has not been released yet, but has my attention.)

    Also, minor, but you can't use it and charge it at the same time. Plugging it in automatically turns it off. However, the battery life is epic.

    The pairing is easy, however, multiple devices means you have to repair it each time. So going from the laptop to the phone to the radio, gets old real fast.

    I wrote the DCC tech support guys and got a email back with details on how to add a mic on off switch. That way I can set my ham radio to VOX with a BT bridge, and still be able to not transmit when I have to talk to someone. Cool guys.

    The build quality is great. The power in connector is a durable barrel style, not a USB one that will break. It's also replaceable. Most of the parts can be replaced. The headband can be adjusted to fit just right. If it hurts your ears, take the time to adjust it correctly. This is a heavy headset, and it does get hot. Anything that isolates sound also isolates thermally. I'm looking to get a set of cloth covers for the ear pads.

    The mic is great. I can talk on the phone while mowing the lawn or working on a diesel generator.

    I did quite a bit of research before getting these. No one else makes a wireless headset with this quality. The 3M headsets have shorter battery life, hours not days, and worse audio. Direct Sound has bluetooth headphones coming out (EXW-37), but no mic.

    And lastly, looks matter for the military. Sure, they are ugly as hell. But David Clark has a reputation with the military, and it looks professional, while the other brands look plastic or trendy. Often times I'm in the middle of another country working on the generators that power very high ranking people's equipment, and these look like they were issued to me.
