I have long been a fan of "listening" to the vibration signal while collecting data.  But my old 2130 used a clunky adapter for this, and the David Clark earmuffs while working very well, were too uncomfortable and heavy to wear all day.  Plus the sound level was adjusted with a knob with no 'detents' so you never knew how one sound level compared to another.

The 2140 "solved" the adapter problem by doing away with it, but also doing away with a headphone jack.  The only way to use headphones is via the optional Bluetooth transmitter, part of the wireless package that costs an additional $2K.  I initially used this with my earmuffs plugged into a small battery-powered Bluetooth receiver.  Worked well enough, but uncomfortable enough that I just carried the muffs in a tool bucket and only used them when I found something I wasn't sure of.

I went in search of Bluetooth earbuds that would work "well enough" and was pleasantly surprised to find the ISOtunes Pro noise-rated unit below.  With the foam earbuds supplied (3 different sizes) the NRR is 27 dB making them legal to use as hearing protection.  They also have an automatic volume-limiting feature which makes it impossible to actually damage your hearing by turning the volume or gain too high.

The foam earbuds are very similar to earplugs you may already be using, but probably softer and more comfortable.  Battery life is advertised as 10 hours -- I don't know about that, but I have no problem wearing/using them all day, and they are comfortable enough that I do that now.  I keep the gain set very low though (on the 2140 - you always know what it's set at) and only turn up the volume when I suspect a problem.

If you have a 2140 with Bluetooth output, you need to get these.  Of if you just want something really comfortable to listen to music with while you're mowing the lawn or running a pressure washer, these work great for that, although perhaps a bit pricey at $90 USD.  Sound quality is excellent though, as good as any earbuds I've used.  I also like that they give you voice prompts (Power On, Connected, Power Off).

Available on Amazon.

Thanks, Rusty, 
I don't use a 2140 but I was thinking of something like this in only recent days, ear defenders are murder in the warm weather, I wonder can you take phone calls with these? is there a mic input?

Mark, yes you can. I've actually not tried it, but I'll experiment a bit with it. The claim is that if there is a 'steady' noise in the background during a call, that noise will be canceled. I would think most industrial noise would qualify as 'steady.' I'll check it out.

The foam tips are also replaceable, but I've not had to yet. They also come with a single size of ribbed silicon tips, like I typically use, but they are a little large and not as comfortable as the foam.

I would advise against dropping them in the driveway as you leave for work in the dark, because you're likely going to run over them as you arrive home after dark.

See if these are available MarkL. Not the greatest sound (for music), but they work well.

What Rusty suggested is available on eBay UK.  See http://www.ebay.co.uk/itm/ISOtunes-PRO-Noise-Isolating-Bluetooth-Earbuds-27-dB-NRR-10-Hour-Battery-/252692598134.  In addition, the ISO Tunes FAQ says they ship worldwide at an additional $US20.  The parent website is at https://isotunesaudio.com/products/isotunes-pro.

I played with these for a while, but I'm rarely doing route collection anymore so they are just collecting dust on my desk:

I believe the noise isolating earbuds Shoveldr links to are not Bluetooth.  But you could just buy a small rechargeable Bluetooth receiver and plug your headphones into that.  Here is a link to one by TaoTronics on Amazon  I don't own this, but I do have some TaoTronics Bluetooth earbuds and they sound as good as my old Bose earbuds did.

Thanks for the head's up on these Rusty, they look like a good unit!

Unfortunately our site won't approve them as the wire 'breaks' the ear muff seal when you wear muffs in double hearing protection zones. (don't mention what the safety glasses do to the seal!!)

"Double hearing protection zones"..... on my.  I have David-Clark behind-the-head ear muffs (for use with a hard hat).  I wonder if wearing normal earplugs, and then the muffs over those would work... would I still be able to hear the signal?  Will have to give it a try.  The DC muffs work flawlessly with a Bluetooth receiver and the 2140, but they're just so heavy and hot (I bought cloth 'covers' for them which help) that I can't wear them all day long.  My intent was to remove the long coiled cable, and mount the receiver directly to the muffs, but I never got around to that.

To be clear, the ISOtunes are well designed (flexible 'retainers', voice prompts, auto off when signal is lost), but I'm having a bit of trouble keeping the earpieces in.  The medium are a little small, and the large are a bit too big (and I think my ear canals are also different sizes).  They come with a set of silicon, flanged earpieces also, but they are a tiny bit too small (only come in one size).  I will look for other ear piece options.

I guess you can't have everything!

Are you saying they respond to your voice, ala Alexa?

Any recommendations on settings in the 2140 Bluetooth Listener page?

No, they don't respond to voice prompts. The control buttons on most all Bluetooth earbuds are closer to the right ear, so when you have them on you can't see the buttons. There are usually 3: minus (volume down), On/Off/Pair, and plus (volume up). So you put them in and press what you think is 'On' and if you got the right button, she says "Power On" (or Power Off, or Pairing, or Connected).

I leave my Filter Off on the 2140 and the gain set at 30db to start with. I adjust the gain depending on how loud or quiet the machines are. If I don't hear anything at 30db I feel the machine is good and move on. When I hear something that concerns me, I play with the filters to isolate the frequency.
