I use sony earbuds. 7.99 at Meijer. I've run in the rain for hours with them and they keep going strong. I would never waste my money on expensive headphones.
You can get them for less than half I paid on Amazon right now.
For another $100 you can go to the earplugstore.com and have custom ear mold made for them.
It's beyond good and when they fit to your ear, off the hook. 😎
Shure se215
They are a little pricier than what I would normally buy, but I happened to have a $50 amazon GC. I'm glad I bought them. They have excellent sound quality, bass, and noise isolation, for earbuds. Plus, their unique wiring allows you to change the wires easily and for a cheap price.
Sony MDR EX38IP/BLK (earbuds with volume control and mic on the left cable). They get plenty of abuse from running and gym work, and everyday use during my commute. I paid $25.
My Shure e3c's were expensive and only lasted slightly longer than a year before they started shorting out in one ear, so since then I go cheap on earbuds.
