I have to agree with ya Bubba, but just can't 100% - for me anyway.
To me, sound quality has to be there, but a few other things must work for me.
I need comfort to prevent them from becoming annoying.
The cord can't be to long to get tangled or to short to prevent me from standing up when the machine is on the ground.
Material quality and craftsmanship - they should last a reasonable time of outdoor use.
And there are other factors that come into play but I'm cutting this short.
If it didn't matter to me, I would go get me a set for under 5 bucks and that would be that.
On my home stereo, myself and others sure hear a big difference if I jack in my Grado RS-1, or one of my Bose, then really talk about a difference on a 3 or 4 dollar set, even tho they say 20 - 20,000 Hz frequency, I hear and feel a difference as well as others. I know my hearing don't go that low or go that high, but what I do hear is a difference enough that I prefer some over others.
If I run a machine and air test a small target (like a gold picker that's at just detectable range), that just barely change the threshold a tad, I can discern a very small change better with some headsets compared to others.
On a single tone machine, I want the tone language to be conveyed the best I can get to my ears.
Otherwise - I see those $1.99 ear buds - but they are just not for me.
If your happy with what your using, I think that's great, I use what keeps me happy. I'm just the kind that I won't take my sport car and put on 4 for $79 set of tires on. I just wouldn't feel right, sure they both roll down the road, and sure they works for others, but I sure wouldn't feel right for my use.
Not trying to stir the pot here - just my 2 cents HH
