The (passive) network is connected between the amp and headphones. How the device operates is grounded in the research of the acoustics of human hearing. It has the following good qualities,
-connecting it between the amp and headphones lowers volume only slightly, perhaps about -3 dB;
-it is compatible with a wide range of headphone rated impedance, 16 Ohm to 300 Ohm;
-true that I haven't used it to listen to every recording out there, but it would seem that the improvement of apparent localization forward is good for a wide range of recordings without adjusting the ( not adjustable) device;
-the network is contained in a small compact case 3 inch (7.5 cm) by 1.5 inch (3.8 cm) by .75 inch (1.9 cm);
-the price is only about 11 US Dollars.
So would you want to buy such a device from a fellow DIYer, or not, and why or why not?

Pete

My impression is that I've developed a very useful network. A large part of my positive take on it is based on subjectively how playback of stereo music recordings are improved by inserting my network between amp and headphones. So I might be biased as it is my original creation.
Anyway, I have a small ad on the Net, and after about 4 months of the ad being posted, I haven't received any responses, let alone someone saying that he/ she would like to buy it. In the ad I solicit questions and comments. So I am trying to understand why I'm receiving such a negative response. My expectation was that there would be at least some interest in it. Any suggestions as to how I am "off the mark" in thinking that I could make a little bit of cash selling my device are appreciated.

one idea: If you can afford the investment, make a few samples and ask some people who's opinions are regarded to evaluate it and provide you with their assessment - a 'review' if you like.
Hi,
Head-Fi.org - Headphone forums and reviews for audiophiles
is probably the place to drum up some interest.
Original creation ?
Xfeed is not exactly new, dates back to at least Linkwitz 1971.

I think you would do better by advertising in a music orientated publication, rather than trying to sell a product to people
who usually build much of their own gear. There are many of these circuits available for DIY with a little research.
Thanks, that is a good idea. Making a few samples would not be expensive at all. However, in the past I've run across "audio authorities" who request a fair amount of compensation to do an evaluation. Getting several people's valued opinion would certainly help me in deciding whether it would be worthwhile trying to do something commercially with it. After that, though, I'm still stuck with figuring out if I can successfully market it on a small scale.
Thanks for the reference to Head-Fi.org. Yes, of course Xfeed for headphones is not new. All that I'm saying is that my circuit design to me looks different from what others have concocted. It's quite possible that someone else has cooked up the same thing some where, and I simply don't know about it. To my mind, the fact that inserting it between the amp and headphones results in a minimal reduction of volume is indicative of a "new" Xfeed circuit design.

Yes, I totally agree with you. Thanks for the input. It was not my intention to try to get people here to buy it, rather I am attempting to understand the lack of response to my ad at Audio Asylum, that being kind of not the best site at which to place my ad.
Thanks,
Pete

One of my HP amps (the FIIO E12) has a switch to activate that. The switch has been permanently stuck on OFF position since day 1.
One way to do this on a small scale would be to sell through one of the internet stores, if they like your product well enough to recommend it.
But remember, you're trying to sell to a subset of a subset of a subset of the audio market. Many people are also reluctant to buy
something from an unfamiliar business. And, the price may be too low. Even if your parts cost is only $3-$4, the selling price should
be more like $15-$20. I agree, you should focus on the headphone sites.
It's just that I am not a fan of "special effects", being them surrounds, xfeeds, or anything really.
