Question on Headphones

		Quote:			Posted by Bugar
	Allright  Eugene52=Your'e the MAN, have talked to some headphone folk, asked this question=they don't have a clue it seems, different detectors put out different volumes/decibles/sounds, thru the headphones=OK= what i would like to know IS there a way that a device can be made to fit between the headphone jack, or at the jack, (somewhere) that can make the headphone output be adjusted like in BASS or TREBLE, like a radio, I would think this would be readily accepted as some detectors, and some headphones are, tinny-some blarey- some just plain tacky sounding, something that a user could make it more plesant to use and customize the sound to their hearing an be more tolerable- Thank You-Bugar's Inquiring mind

I have purchased one of the original RATPHONES VTF headphones made by DetectUSA. They were short lived, not a lot of interest.
I did contact Rick back in 2005 asking him about a variable tone control. He just happened to build a set bought it and gave it a test run. It worked perfect on my Garretts, White's MXT, Tesoros and Minelab Musketeer. I finally could adjust the miserable tone of the MXT into a pleasant sound. Anyways, not much interest in them, so he stopped making them. Shame I sold my set years ago without looking inside at the guts. I ave contacted Rick last year inquiring about possibly getting another set, he emailed back "...why would you even want them...", no response from him after that. Recently tried getting touch with him asking about them again and possible give me an idea on how to make the tone control. No response back. Have noticed he no longer has his Ratphones DetectUSA website up. It has turned into his personal homepage. He's been an electronics tech, produced records and is a musician. Looks like he new his stuff and tried giving detectorists headphones that were superior to the rest on the market. Too bad detectorists did not take advantage of his products to keep him in business.

At any rate, I have done lots of research over the last several months and believe I just about came up with a working model of a tone control could be passive or active. Also, if active would  employ an amp to increase small sounds and with high volume limiters.
Everything is still on the drawing board. I already built a working headset with soft limiters.......It's a learning process as I am not a professional electronics person.

So I have a bunch of ideas and have parts to make two more headphones. Over the next few winter months will try to come up with something. Finding electronic parts locally in Canada is a real pain, if you can....basically have to order everything from the US.

My setup is a Logitech Free Pulse Bluetooth headphones with a koss eq (I like to change audio response using a Koss EQ unit) Logitech Free Pulse headphones are a very light unit, even in the hot summer is a pleasure to my ears, they let me dig in the ground without any cords. If you use a Bluetooth unit you'll find that the target sounds an inch or two away from the real location, this is due audio lag, but is quite simple to locate and pinpointing the target with some practice.
