I have a pair of headphones, cheap, ugly, made in China, and they sound great.
Don't get much from that, do you? There is no basis for comparison.
Now, what if I tell you that I went to a high end audio shop (McIntosh etc) and listened to a pair of $200 headphones and they did not sound any better than my $20 pair. Better made, may last longer, but 10x the price.
Again, what if I tell you that these cheap headphones made me question why I have a room and tons of equipment dedicated to listening to music when I can get a comparable sound for $20? These things are ridiculous for the price.
If you want an inexpensive way to know what good audio sounds like, get a pair of these, if you can find a promo code or 2, they get even cheaper.
