I work on a site that has just bought 2140s, and we use them in areas that require double hearing protection. This rules out using Emerson's recommended bluetooth headset (the david clarke unit). The older Sensear noise cancelling items don't work with the 2140's bluetooth protocol and Peltor don't have a neckband unit that will fit under a helmet. Has anyone found a good noise cancelling headset that works with the 2140?

Oh and yes I emailed Emerson, their response? They emailed me a google search for bluetooth headphones, not really the professional response I was after considering how many of their clients require an industrial hearing protection solution.

Update: We ended up with Sensear SM1P's (with updated firmware), which work but can be a bit quiet in noisy areas.

Rang, DC muffs with a Bluetooth receiver, worn over a pair of regular earplugs?

Hey rusty, did you end up going for wi-fi? With your 2140? And head phones? And how is that working if so.  Am looking at a quote now and they are listed as optional extra which is what I expected. Is the extra expense justifiable? rgds.

We went with the bluetooth but have had some issues. I got a pair of Sense-ear SM1P's (Behind-The-Neck) to work, but for noisy areas they are a bit quiet.

I found anything that had a wire from one ear to the other was really uncomfortable when the ear muffs pushed down on the wire. But any generic audio (A2DP) headphones worked.

As far as the 2140 goes there is a firmware issue that causes the screen to flash when the Gain is up, very annoying. And if you have multiple headsets, and swap from one to the other the 2140 will crash on an Xshell.exe (firmware) shutdown. Emerson have suggested to reload the firmware but this has already been done twice.

Also the wireless hasn't been used as much as we thought, it's really just a convenient way to dump data with any cables, but still clunky. The ethernet has issues as well, the data collector has to be shut down and restarted before it will connect.

Route loading and dumping is waaay quicker though (over ethernet), so one big plus.

Hope this helps.

I did go with the "wireless" option on the 2140, about $2000 USD.  Partly to use the headphones (because I don't think there's another way), but also to upload/download wirelessly when I'm in the field.  I am very happy with the headphone performance, but not the wireless.

I discuss the bluetooth headphones I use at length in another topic so I won't repeat that here.  They are "noise limiting" (that is, they cannot actually damage your hearing), and noise isolating, but not noise canceling (is that even approved as hearing protection?).  If I needed "double protection", I would simply wear my noise isolating (24 dB) earphones, and wear a pair of "cushy" ear muffs over those.  The "wire" would cross under the muffs, but it's small so don't think that would functionally compromise the protection level (but that might be a "technical" violation).  I thought the "blinking" of the screen when the signal noise (or the gain) is high was a safety feature, to keep you from damaging your hearing.  I've never read or heard that, but it seemed logical to me.

As for the wireless, my intent was to connect the 2140 directly to my laptop in the field via an adhoc network, such as my camera uses, or an Eye-Fi card.  But I have a Surface Pro 3 running Windows 10, so that's apparently not possible.  Windows 10 doesn't support adhoc networks, but it's still possible to do it via the command line.  But the built-in wifi card in the Surface doesn't support adhoc networks in any form, or at least not the "old" ways.  (However, I have no problem tethering my Surface to my iPhone to connect to the internet when my home service or router is down -- go figure)  I got it working with a small battery-powered HooToo Bluetooth hub (access point), but I had to use a static address on it, which I found interfered with my wireless in the office.  I guess I could have figured it out, but it was just too much hassle at that point.  So I just always use a cable.

Windows 7 was apparently the last version with native support for adhoc networks.  I assume that would work with the 2140.  I have never used the wireless option at home (office) except to test it.  The USB connection is plenty fast enough for me.  I wanted to connect wirelessly to my Surface for two reasons:  for convenience when sitting/working in my truck, and to avoid using the crappy mini-USB connector on the meter which is NOT going to last.  Using the mini-USB on the 2140 it was a terrible idea!  It's simply not robust enough for a device like the 2140.  My cable is already loose in the connector -- it's only a matter of time before it quits working, and I have to send it in for repair.

Now Rang, are you still... oh nevermind. Have you moved up to 2140 yourself?
