Evolve2 55

Jabra Evolve2 55. I’ve used them in operational locations and no one heard the guys around me.

Was in the exact same situation. I got the Jabra evolve2 55s over the 65 flex. Forgot the reasoning, but at the time I was comparing them the 55s were better for my use case. I've been happy with them, although wind makes falls difficult. The noise suppression on the mic is strong and excessive noise will cut out your voice. 

Jabra evolve 2 55 mono, love the comfort

I personally use Jabra Evolve2 55 (under $200 on Amazon) and Jabra Evolve2 65 flex (my favorite). I use them primarily for the mic noise cancellation.

Jabra Evolve 2 such a workhorse

Yeah, as someone who works with noise canceling headphones (Jabra Evolve 2) and uses personal headphones such as the Sony XM4… get Resound hearing aids or similar tech that addresses feedback. Resound specifically has a feature that will reduce feedback to almost nonexistent. I personally bought the Noahlink so I could fiddle with that feature until I got it how I liked it. I suggest considering this and doing some research. Phonaksdo have whistleblock for their feedback tech but it isn’t as good as Resounds DFS Ultra

The Evolve2 series are outstanding. Now if you want to cancel ALL outside noise, maybe David Clark HBT40? I had a pair for datacenter work, paired to a cell phone. Couldn't hear anything from the equipment in the cage, just the phone conversation.
