The Bose QuietComfort Ultra Earbuds excel in wireless convenience, effective noise cancellation, and are sweatproof, suited for exercise and air travel with a well-rounded sound quality, making them great for music, gaming, and TV. The Etymotic ER2SE, being less expensive, offers excellent sound isolation and accuracy but lacks a microphone, active noise cancellation, and wireless capabilities, so they're less convenient but good for focused listening. The Bose provides a more versatile, high-quality experience suitable for various contexts, but with a higher price tag, while the Etymotic provides wired reliability and top-tier sound isolation for discerning listeners on a budget.

"Bose put the time in to fix the major issues with the previous earbuds, and the Bose QuietComfort Ultra Earbuds are very befitting of its price point. While you might be tempted to save a few bucks and go with the Bose QuietComfort Earbuds II on sale, fight the urge. There are enough upgrades here to justify the newer model."

"Etymotic isn’t playing around: it takes audio seriously and has mastered the art of the noise-isolation earphone. Sure, the fit of the earbuds looks silly but it’s a signature Etymotic thing and could be considered charming by some. If you’re looking for best-in-class audio for a realistic price, the ER2SE is it."
