The Bose QuietComfort Ultra Earbuds (2nd Gen) are a masterclass in refinement. Building on the legacy of the original QuietComfort series, this latest iteration elevates nearly every aspect of the true wireless experience. From world-leading noise cancellation to immersive audio and ergonomic comfort, Bose has crafted a product that feels both premium and purposeful. In a market crowded with contenders, the QuietComfort Ultra stands out not by doing everything, but by doing the essentials exceptionally well.
Design and Comfort
Bose has always favored function over flash, and the QuietComfort Ultra Earbuds reflect that philosophy. The design is sleek and understated, available in Black, White Smoke, and Deep Plum. Each earbud is slightly bulbous but ergonomically contoured to nestle securely in the ear. The short stem sits flush, minimizing protrusion while maintaining a balanced weight distribution.
Comfort is a standout feature. The earbuds come with three sizes of soft silicone ear tips and stability bands, allowing users to find a personalized fit that stays secure even during movement. Whether you’re commuting, working out, or relaxing at home, the earbuds remain comfortable for hours. Their IPX4 rating ensures resistance to sweat and light splashes, making them suitable for everyday use.
The charging case is compact and pocketable, with a matte finish that resists fingerprints. It now supports Qi wireless charging, a welcome upgrade from the previous generation. The USB-C port remains for fast wired charging, and the LED indicators provide clear battery status at a glance.
Noise Cancellation and Transparency Mode
Bose has long been the benchmark for active noise cancellation, and the QuietComfort Ultra Earbuds reaffirm that reputation. Using a multi-microphone array and adaptive algorithms, the ANC system dynamically adjusts to your environment, suppressing ambient noise with remarkable precision. Whether you’re on a plane, in a café, or walking through traffic, the earbuds create a cocoon of quiet that few competitors can match.
Transparency mode is equally impressive. It allows ambient sound in without distortion, making conversations and situational awareness feel natural. The transition between ANC and transparency is seamless, and users can toggle modes via the touch controls or the Bose Music app.
Audio Performance
Sound quality is where the QuietComfort Ultra truly shines. The earbuds feature dynamic drivers tuned for Bose’s signature sound profile: rich bass, balanced mids, and crisp highs. The low end is warm and full-bodied, giving music a sense of depth without muddying the mix. Vocals are clear and present, and instruments are well-separated, creating a spacious soundstage.
CustomTune technology takes personalization to the next level. Upon setup, the earbuds analyze the shape of your ear canal and adjust the frequency response accordingly. This ensures optimal clarity and balance tailored to your unique anatomy. The result is a listening experience that feels intimate and immersive.
Bose also introduces Immersive Audio, a spatial sound mode that simulates a surround sound environment. While not as expansive as Dolby Atmos, it adds a layer of dimensionality that enhances movies, games, and select music tracks. The effect is subtle but effective, especially when paired with high-quality content.
Connectivity and Controls
The QuietComfort Ultra Earbuds use Bluetooth 5.3 for stable and efficient wireless connectivity. They support AAC, SBC, and aptX Adaptive codecs, ensuring compatibility across Android, iOS, and Windows devices. Multipoint pairing allows users to connect to two devices simultaneously, making it easy to switch between a phone and laptop without re-pairing.
Touch controls are built into each earbud and can be customized via the Bose Music app. Users can manage playback, volume, ANC modes, and calls with simple gestures. The controls are responsive and intuitive, though some users may prefer physical buttons for precision.
The app also offers firmware updates, EQ adjustments, and battery monitoring. It’s cleanly designed and easy to navigate, enhancing the overall user experience.
Battery Life and Charging
Battery life is solid, though not class-leading. The earbuds offer up to 6.5 hours of playback with ANC enabled, and the charging case provides an additional three full charges, bringing the total to around 24 hours. While this won’t last through a long-haul flight without a recharge, the inclusion of fast charging helps mitigate the limitation. A 15-minute charge yields up to 2 hours of playback, which is perfect for quick top-ups.
Wireless charging via Qi pads adds convenience, and the USB-C port ensures fast wired charging when needed. The battery performance is consistent, and the earbuds hold their charge well over time.
Call Quality and Microphone Performance
Call quality has seen notable improvements in this generation. The earbuds use beamforming microphones and noise suppression algorithms to isolate the speaker’s voice from background noise. Whether you’re taking a call in a busy street or joining a virtual meeting from a café, your voice comes through clearly.
While wind noise can still pose a challenge, the overall performance is among the best in the category. The ENC system works effectively to reduce distractions, making the QuietComfort Ultra a reliable choice for professional and personal communication.
Verdict
The Bose QuietComfort Ultra Earbuds (2nd Gen) are a triumph of thoughtful engineering. They don’t chase gimmicks or overload users with features. Instead, they focus on delivering exceptional noise cancellation, immersive sound, and all-day comfort in a refined package. Whether you’re a frequent traveler, a remote worker, or a music enthusiast, these earbuds offer a level of polish and performance that justifies their premium price.
Bose has once again proven that quiet can be powerful and that true wireless audio can be both elegant and effective. If you’re looking for a top-tier listening experience without compromise, the QuietComfort Ultra deserves your attention.
