I really enjoy using the 'Wasp' headphones with the Tesoro's and Classic's and some other models because, with my hearing loss, the audio option is very beneficial. Currently I am using my Pro Star headphones until my Killer B 'Wasp' set gets repaired and returned .... hopefully before spring weather arrives and drives off the cold snap.

I realize that the mono-tone beep-or-no-beep 2-filter machines don't require a super-duper quality headphone set.
I disagree with that, Tom. Not all two-filter models benefit from higher quality headphones to hear a weaker, softer, deeper target response, but those are usually the models that rely on a saturated audio as well as a clipping filter type circuitry. With those models, it is either a full response or no response. That would include models like the old Bounty Hunter Big Bud Pro and some others based on that circuitry concept.
One of the things I liked about the Tesoro models, especially since mid '83 when we got the slow-sweep, quick-response Inca, was that those models used a good modulated audio, and with better quality headphones it helps to hear the softer or weaker responses from smaller and/or deeper targets. It doesn't matter if they are a single tone or multi-tone response, as long as they have a good modulated audio, not a fully processed and saturated type circuit.

Since they are not so reliant of subtle tones and pitches, as a full tone-TID machine (like an explorer) is, for instance.
Oh, but they are. It is true that some higher-dollar or upper-end detectors might have a multi-tone audio option [size=small]
(but so do some lower-cost offerings)[/size], and even then it is all a matter of how they process the target response. Some low-end detectors, like a White's Coinmaster or Teknetics Delta and others, do not have a modulated audio and almost all that you hear gives a full-audio response.
Some models provide more operator options, like a Teknetics Omega. It has a more processed 3 or 4 Tone ID option which is okay for most casual coin shooting, but the single and 2-Tone choices are very modulated. That makes for more audio response 'information' and using a top quality headphone can be a real benefit. It can also help those of us who have lost a lot of hearing, making it more difficult to hear the more subtle weaker/deeper responses.
It also depends on if they are using a true, Threshold-based All Metal mode, or a motion-based Discriminate mode and the particular model used.

But if anyone here IS using killer-B's with their 2-filter Tesoro (like a silver sabre, or any other similars):
How do you have the two switches set when using your Killer B's? Ie.: the up or down position, and why for each setting ?
Some models only have one 'compatibility' switch, and some, like my Killer B Wasps, have a limiter switch, too. Looking at the ear-cup, the front or left-side toggle switch lets you select a full-audio performance, or toggle to the 'limiter' position. That will limit the loudness and 'brightness' of the audio most often from shallower or closer or larger-size targets to be softer on the ears, more like a target at, let's say,
