@mychaelp Had this been a year or two ago, I would've suggested the following:
Panisonic RP-HJE120-K @~$25 for the inline mic version
I bought a pair of these about a year ago, coil them in my pocket on a daily basis, and spent about 6 months sweating all over them. However, they've yet to start failing, and have provided a decent balance of audible highs and lows we all seek from our audio reproduction devices.
Unfortunately, according to this guide, their current $10 price point direct from the manufacturer is considered sub-par. Although it could be argued that with the quality I've experienced with these, you're likely to find something better in Panisonic's current in-ear lineup for the money you're looking to spend. As for what though, I have no other anecdotal reference to suggest from.
Also worth noting with my suggestion: Buying directly from Panisonic is a little strange, and can be a bit unsettling for some as they required me to send them a scan of my ID to confirm that I was in fact myself.
