The Bose QuietComfort Ultra Earbuds feature active noise cancelling, great for use in noisy environments or during air travel, are sweatproof certified, and have a more compact design, making them highly suited for exercise and portability; they also offer wireless convenience with a moderate battery life including the case, yet may fall short in battery life compared to others. In comparison, the EPOS PC38X headphones boast superior microphone quality, a spacious soundstage, are optimized for gaming with no latency due to their wired connection, and offer an excellent overall sound quality, suited for music, calls, and gaming. The Bose is more expensive but excels in active lifestyles and noise isolation, while EPOS stands out in home gaming setups and immersive listening experiences but is less suited for outdoor activities and noisy spots due to their open design and lack of active noise cancellation.

Christian Thomas | October 2023
"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."
