For comfort and brain-shaking boom, custom-fitted earbuds are king. For those who don't want to drop a G on accoutrements you'll inevitably coat in wax then lose, check out LiveWires
At only $250 (around half the competitors' cost), LiveWires are the most cost-effective in-ear option this side of Q-Tips. Nevertheless, LW's still have dual drivers, enhanced signal-to-noise ratios, and a perfect canal-molded fit that'll keep the inserts put and give you the sensation you're not even wearing them (like perfectly tailored pants, or no pants). Also unlike the competition, LWs have tangle-preventing rotating connectors attaching the earpieces to replaceable cables -- so you can feel free to frantically chew through the chords when "Rump Shaker" segues into... that other song by Wreckx-n-Effect
As with any fitted pair, you'll need an ear mold from an audiologist -- buy a set, and they'll happily make a referral, provided they can hear the phone over the jaunty beats of "Knock-N-Boots".
