I'm finally investing in my own headset to use as I freelance, so I always have something comfortable to wear. But I'm feeling rather overwhelmed by the options and would like some help! The last threads I found about headsets were from a few years ago.
Specifically, what is confusing me is the variety of connectors. As I look at various headsets, some of them specify that they come with XLR (like the Eartec Slimline Single, and Production Intercom's 710 & 910), and some don't (like the RTS PH-88, and the Eartec Fusion and Eartec Cyber). On the Eartec Slimline Single page, the description says that it comes with XLR, but on the side of the page, where it says "Buy Now," the only options are for other connectors - one- and two-pin Motorola connectors for radios. So are those adapters? Or are those some options you can choose instead of the XLR?
What does A4F and A4M mean? (I'm guess the F and M are female and male, but beyond that...I'm lost.)
I'm worried about getting something and then not being able to use it at the various places that I work. But I don't want to rule something out if I can just get an adapter and call it a day. What is normal? Is it even as simple as getting adapters for the various types of connections you might encounter? I think I've seen 4-pin XLR as pretty standard for headsets but when I started shopping I became overwhelmed by what looks like lots of options for connectors.
I want to get a good headset, and I'm willing to spend $100 or $150 to get something decent. Comfortable is key - I wear glasses and am rather prone to headaches. I'd prefer a single-sided muff, and want to be able to wear it on both sides (though if I have a really comfortable one, maybe I won't need to switch from the left ear, where I wear my headset primarily, to the right!). A nice bonus would be something that would shut off the mic if I flipped it up - I know some headsets come with that feature, but most of them don't seem to and it's not crucial. I'm pretty used to doing that manually. Obviously something that is reliable and will last is important too!
Is it better to order from the manufacturer or a dealer? Some of the manufacturers don't seem to sell directly - or if they do, they make it difficult to figure out how. I'm having a really hard time finding prices for some of the headsets that I'm looking at, which makes comparing them all the more confusing.
All this to say that I really need some guidance! Any information, from basic explanation about what is industry standard to specific recommendations about headsets to purchase and where/how to get them, would be helpful. I always thought that headsets weren't that complicated, but shopping for one has made me second-guess everything I thought I knew!

Thanks all!!!
