[Solid review from The Wirecutter]
After sifting through literally hundreds of options, seriously considering nearly 150 models, testing the top 40, and calling in audio experts to blindly evaluate the top 20, we’re pleased to report that if you want to buy an inexpensive pair of in-ears, you should get the Panasonic RP-TCM125 “Ergo Fit”. They sound good, they have a one-button remote and mic, they fit well, they come in a variety of colors, and they’re less than $15.
