Design and Comfort
The QuietComfort Ultra Earbuds maintain Bose’s signature focus on comfort and practicality. The slightly larger design might seem bulky at first glance, but the soft silicone ear tips ensure a secure and comfortable fit. They’re perfect for extended listening sessions without causing ear fatigue.
Available in black, white, and sandstone colors, the earbuds sport a modern, understated aesthetic. The magnetic charging case is compact and pocket-friendly, making portability a breeze.
Sound Quality
Bose has always been synonymous with outstanding sound quality, and the QuietComfort Ultra Earbuds continue that legacy.
- Bass: The low end is deep yet controlled, offering satisfying punch without muddying the mids.
- Mids: Rich and natural, with vocals and instruments given plenty of space to shine.
- Highs: Crisp and detailed, providing a sense of airiness and sparkle that complements any genre.
The standout feature here is the Immersive Audio Mode, which adds a layer of spatial audio to your music. This feature doesn’t require specially formatted content, making it accessible for streaming platforms like Spotify and Apple Music. The result? A 3D-like listening experience that feels as if you’re in the middle of a live performance.
Active Noise Cancellation (ANC)
Bose continues to lead the pack in ANC technology. The QuietComfort Ultra Earbuds effectively block out background noise, from low-frequency hums to higher-pitched chatter.
The adjustable ANC levels allow you to customize the noise-canceling intensity based on your environment. Additionally, the Adjustable Transparency Mode lets you stay aware of your surroundings when needed, with audio clarity that’s second to none.
Battery Life
The battery performance of the QuietComfort Ultra Earbuds is solid, though not groundbreaking. You’ll get 6 hours of playback with ANC enabled, or 8.5 hours with ANC off. The charging case provides an additional 18 hours, bringing the total to 24 hours.
Fast charging offers 2 hours of playback with just 20 minutes of charging, and the case supports Qi wireless charging for added convenience.
Microphone and Call Quality
Equipped with 6 microphones (three per earbud), the QuietComfort Ultra Earbuds excel in call quality. The beamforming mic array ensures your voice comes through clearly, even in noisy environments. Wind noise and background chatter are minimized effectively, making these earbuds an excellent choice for business calls or video conferences.
Connectivity and Features
These earbuds come with Bluetooth 5.3 for stable and seamless connectivity. They support multipoint pairing, allowing you to connect to two devices at the same time—great for switching between a laptop and smartphone without hassle.
The companion Bose app provides intuitive controls for EQ settings, ANC levels, and firmware updates, though it lacks advanced EQ customization compared to competitors like Sony.
