MEElectronics M9 Earphones, maybe not the best but certainly a great deal - General Tech  1

"There are a lot of contenders in the earphone market. The prices range from $10 up into the $200s or more for those simple little speakers folks plug into their ears for a few hours at a time, listening to a variety of forms and genres of music. Some folks can’t tell the difference between the low-end ones and the high-end ones, and prefer affordability over demonstrable sound quality. After all, if you can hear something, the earphones are working well, right? Clearly, we audiophiles know there is a difference. However, we, too, fancy ourselves frugal, so we’ll find the highest-quality au dio devices we can afford. Enter the MEElectronics M9 earphones, a $20 set of earphones which sound like $80 earphones."
