Bose has once again taken a thoughtful step forward in the true wireless earbuds space with the announcement of the second-generation QuietComfort Ultra Earbuds. At first glance, they may look familiar—retaining the design language and comfort that made the original QuietComfort Ultra Earbuds popular—but under the hood, Bose layered in AI-driven refinements that promise smoother, more natural noise cancellation transitions and clearer calls. Announced on June 12, 2025, and slated to arrive later this summer for $299 in black, white smoke, and a limited deep plum, these earbuds show that Bose isn’t content to rest on its laurels in the increasingly crowded ANC market.

If you’ve ever been listening to music or a podcast and had the noise cancellation abruptly clamp down when an ambulance siren passes, you know how jarring it can feel. The original QuietComfort Ultra Earbuds already offered top-tier ANC, but Bose’s latest iteration introduces an updated AI algorithm on top of its CustomTune calibration to personalize audio and noise cancellation to the unique contours of your ears. Now, when a sudden noise spike occurs—like a passing train, a siren, or a gust of wind—the earbuds dial ANC levels more gradually rather than slamming into maximum cancellation immediately. This subtle approach in awareness mode means you’re less likely to feel like your audio is being abruptly swallowed by the environment, preserving immersion while still blocking unwanted noise.

Behind the scenes, this refined adaptive ANC leverages machine learning models that have likely been trained on diverse noise scenarios, enabling the earbuds to predictively modulate cancellation intensity. While Bose doesn’t publish the exact architecture of its AI system, the concept is similar to what we’ve seen in higher-end headphones and even some hearing aids: a continuous feedback loop of listening, assessing, and adjusting in near real-time. As a result, the transition between hearing ambient sounds and blocking them out should feel more natural and less like a binary on/off switch. For users who frequently move between quiet and noisy environments—say, stepping off a quiet street onto a bustling sidewalk—this smoother handoff can enhance comfort and reduce ear fatigue over long listening sessions.

Another area where Bose applied its expertise is in call performance. The second-gen QuietComfort Ultra Earbuds borrow noise-suppression techniques originally developed for hearing aids to isolate the speaker’s voice against challenging backgrounds. With eight microphones per earbud working in concert with dynamic mixing and adaptive filters, the system reduces distractions like wind rustle or office chatter, keeping voices crisp and intelligible whether you’re using a single bud or both. This is especially welcome for people who take calls on the go—remote workers, frequent travelers, or anyone juggling calls in less-than-ideal acoustic environments.

Comfort has always been a strong suit for Bose’s QuietComfort line, and the second-gen Ultra Earbuds maintain that reputation with a stable, ergonomic fit designed to stay put during activity. But Bose didn’t stop at fit: the new model introduces a “wax guard” that helps reduce earwax buildup in the speaker meshes, making cleaning simpler and extending the earbuds’ effective lifespan. Additionally, if you find capacitive touch controls too sensitive (leading to accidental pauses or mode switches), you can now disable them in the Bose app—handy for fidgety fingers or when wearing gloves in cooler weather.

Battery life remains consistent with the prior model—up to 24 hours total with the charging case—yet Bose added wireless charging support for the case itself. You can pop it on a Qi pad for a quick top-up rather than digging out a cable, which aligns with the move toward cable-free convenience. Of course, wired charging via USB-C is still available for faster replenishment when needed.

Bose didn’t limit its summer refresh to earbuds. The SoundLink Micro Bluetooth speaker gets a 2nd Gen upgrade for $129, adding a USB-C port (finally), doubling battery life from six to 12 hours, and improving high-frequency clarity. It also joins Bose’s mobile app ecosystem, letting you fine-tune EQ settings and reassign shortcut buttons—features that previously resided in larger, pricier speakers. For existing Micro fans, the extended runtime and app integration may be tempting reasons to upgrade.

More exciting, perhaps, is the introduction of the SoundLink Plus, a new portable speaker positioned as a premium offering. Available for pre-order June 26th at $269 in black and blue dusk (with citrus yellow joining on June 18th), it sports a single subwoofer, a tweeter, and four passive radiators, promising robust sound for its size and up to 20 hours of playback per charge. With IP67 waterproofing, it can be submerged briefly or float if it goes overboard—perfect for poolside parties or beach trips. The feature set signals Bose’s intent to compete more aggressively in the portable speaker segment against rivals from JBL, Ultimate Ears, and others, offering a balance of sound quality, durability, and battery endurance.

The wireless audio market in mid-2025 is fiercely competitive. Sony’s WH-1000XM6 and Apple’s AirPods Pro 2 remain strong contenders in ANC and ecosystem integration, while newcomers from smaller audio specialists push innovative features or aggressive pricing. By doubling down on AI-enhanced ANC, personalized calibration, and call clarity, Bose aims to differentiate itself through a refined user experience rather than raw specs. Comfort, in-ear hygiene, customizable controls, and wireless charging round out a package that emphasizes thoughtful details over flashy gimmicks.

For audio enthusiasts who prioritize seamless transitions between cancellation and transparency, and for those who frequently take calls in unpredictable noise settings, the QuietComfort Ultra Earbuds (2nd Gen) offer a compelling proposition. At $299, they sit in the upper tier of the TWS market, and while they’ll face stiff competition, Bose’s long-standing reputation in ANC and user comfort could make them a go-to choice for many. Meanwhile, the revamped SoundLink Micro and new SoundLink Plus ensure Bose remains relevant across different form factors and use cases, from solo listening to group gatherings.
