Bose QuietComfort Earbuds and QuietComfort Earbuds II Overview

Bose’s QuietComfort series of earbuds includes two standout models: the Bose QuietComfort Earbuds and the Bose QuietComfort Earbuds II. Both models prioritize high-quality sound, advanced noise-canceling capabilities, and comfortable, secure fits. However, they differ in some key areas, including personalization options, noise-cancellation technology, and battery life, providing users with choices based on their specific needs for sound customization and functionality.

Sound Quality and Customization

Both the QuietComfort Earbuds and QuietComfort Earbuds II deliver Bose’s signature high-fidelity audio, with crisp sound across bass, mid-range, and treble frequencies. The QuietComfort Earbuds are designed to offer consistent, powerful sound quality, ideal for an immersive listening experience with enhanced bass and clarity. These earbuds also support adjustable equalizer settings through the Bose QCE app, allowing users to customize audio output to their preferences.

In comparison, the QuietComfort Earbuds II take sound personalization a step further with CustomTune Technology. This feature calibrates the audio and noise-canceling levels to match the unique shape of the user’s ear canal. CustomTune sends a sound chime into the ear, which then bounces back and is detected by built-in microphones. Using this data, the earbuds adjust their settings to provide a sound profile tailored to the individual user. This level of customization offers a highly personalized audio experience, adapting to enhance clarity and richness in different environments.

Noise-Canceling Capabilities

Noise cancellation is a core feature of both models. The original Bose QuietComfort Earbuds feature Bose’s renowned active noise-canceling technology, which effectively reduces ambient noise.

The QuietComfort Earbuds II further refine this feature with proprietary active noise-canceling technology enhanced by CustomTune. By analyzing the specific acoustics of each user’s ear, the earbuds create a more precise and adaptive noise-canceling experience. This allows the QuietComfort Earbuds II to adjust dynamically to different soundscapes, providing enhanced performance in diverse environments.

Fit and Comfort

Both models prioritize comfort and stability, featuring soft silicone ear tips and stability bands in multiple sizes to fit different ear shapes. The QuietComfort Earbuds include three ear tip sizes and a secure in-ear design, ensuring a snug fit that can withstand various activities. With an IPX4 water-resistance rating, these earbuds are suitable for everyday use, including workouts and outdoor activities.

The QuietComfort Earbuds II offer an additional level of fit customization with a Fit Kit that includes three sizes of umbrella-shaped ear tips and three stability bands. This provides a total of nine different size combinations, allowing users to find a fit that feels both comfortable and secure for long-term wear. This model is also rated IPX4, making it resistant to splashes and sweat, so it’s appropriate for active use.

Battery Life and Charging Options

Battery life is robust across both models, though with slight differences. The QuietComfort Earbuds offer up to 8.5 hours of continuous playback on a single charge, and the charging case holds an additional 2.5 charges, bringing total listening time to around 31.5 hours. The case is compact and portable, providing ample power for extended use without frequent recharges. For quick top-ups, a 20-minute charge provides up to 2 hours of playback.

The QuietComfort Earbuds II have a slightly shorter battery life, with up to 6 hours of playback on a single charge. However, the charging case provides multiple additional charges, making it convenient for all-day use. A quick-charge feature also provides about 2 hours of playback with a 20-minute charge, ensuring that users can quickly boost battery life when needed.

Connectivity and Control

Connectivity is streamlined across both models with Bluetooth multipoint capability, allowing users to switch seamlessly between paired devices. This is useful for those who frequently switch between devices, such as taking calls on a phone and then transitioning back to a laptop without having to reconnect manually. The Bluetooth 5.3 standard in the QuietComfort Earbuds II provides a stable connection within a 30-foot range.

Both models also support customizable touch controls, allowing users to manage playback, adjust volume, and switch between noise-canceling modes with ease. The Bose QCE app enables further personalization for each model, including equalizer adjustments, noise control customization, and access to the latest software updates. Users of the QuietComfort Earbuds II can also take advantage of Voice ID through the app, which calibrates the earbuds to their unique voice for improved accuracy with voice commands.

Additional Features via the Bose QCE App

The Bose QCE app serves as a central hub for managing both the QuietComfort Earbuds and QuietComfort Earbuds II. It offers access to features like adjustable EQ settings, touch control customization, and noise-canceling adjustments, allowing users to tailor their listening experience. The QuietComfort Earbuds II benefit from added features like Voice ID calibration and CustomTune audio profiling, giving users greater control over their audio settings and voice commands. For both models, the app simplifies setup, firmware updates, and battery monitoring, enhancing the overall user experience.

Bose Noise-Masking Sleepbuds™ and Sleepbuds™ II Overview

The Bose Noise-Masking Sleepbuds™ were created to help those struggling with disruptive noises at night. Unlike traditional headphones, they didn’t stream music, podcasts, or external audio content. Instead, they came with a collection of pre-loaded sounds engineered to cover ambient noises, such as traffic, snoring, or other common sleep disturbances. Each sound was designed to create a relaxing environment that encouraged sleep by blocking out unwanted noise. This product has been discontinued, but Bose has expressed commitment to ongoing innovation in sleep technology, aiming to support restful sleep in the future.

Following the Noise-Masking Sleepbuds™, Bose released the Sleepbuds™ II, incorporating user feedback and technological upgrades. These improvements included enhanced noise-masking capabilities, increased comfort, and better battery reliability, addressing common feedback from users of the original model. While Bose Sleepbuds™ II are no longer available for purchase on the Bose website, Bose continues to support Sleepbuds™ II owners through customer service and resources.

Noise Masking with Soothing Pre-Loaded Sounds

The original Bose Noise-Masking Sleepbuds™ relied on a selection of ten carefully chosen sounds that played directly from the earbuds. These sounds were optimized to mask a wide range of noises, such as a snoring partner or urban sounds outside a window. Users could select their preferred sound via the Bose Sleep app, with options like “Swell” (ocean waves), “Cascade” (a waterfall), and “Rustle” (gentle wind through leaves). The masking sounds worked by “blending” with external noises in a way that distracted the brain, enabling users to fall asleep more easily.

The Sleepbuds™ II introduced an improved set of pre-loaded sounds, with a broader selection of ambient soundscapes available through the Bose Sleep app. These sounds were specifically designed to help the brain focus on calming audio rather than disruptive noises, creating a “masking” effect that could cover disturbances like nearby conversations or snoring. The updated sound library in Sleepbuds™ II included not only natural sounds but also relaxation-oriented music, allowing users more variety when selecting sleep sounds. Additional sounds could be added with firmware updates, making it easy for users to refresh their options as they developed new sleep habits.

Design for Comfort and All-Night Wear

The Noise-Masking Sleepbuds™ were built for comfort, with small, lightweight earbuds that came in three sizes. Each earbud had a pliable fin that conformed to the upper ridge of the ear, ensuring the buds stayed in place even for side sleepers. These silicone tips created a secure, soft fit, allowing for long periods of use without discomfort. The comfort-focused design helped users move freely in bed without dislodging the buds.

The design of the Sleepbuds™ II aimed to improve comfort and stability even further. Each earbud featured an anti-friction surface to prevent noise from being created when rubbing against a pillow, an issue some users experienced with the original model. Sleepbuds™ II included three different sizes of soft silicone ear tips that could be easily swapped out to accommodate a variety of ear shapes. This improved design ensured that the Sleepbuds™ II stayed securely in place throughout the night, even for users who often change positions or sleep on their side.

Battery Life and Charging Case

With up to 16 hours of battery life, the original Noise-Masking Sleepbuds™ were designed for all-night use. The charging case, which also doubled as storage, provided up to three additional charges, so users could rely on their Sleepbuds™ for several nights without frequent recharging. This design also allowed for quick recharging during the day if needed.

The Sleepbuds™ II utilized nickel-metal hydride (NiMH) batteries, which offered enhanced reliability compared to the original model’s battery. The earbuds provided up to 10 hours of continuous playback on a single charge, which was sufficient for a full night’s use. The redesigned charging case allowed for up to three additional charges and featured better magnet alignment to help users easily place the buds correctly in the case.

Ongoing Support and Research on Sleepbuds Technology

Bose conducted a sleep study in collaboration with the University of Colorado Anschutz Medical Campus to measure the effectiveness of their noise-masking technology. Results indicated that users experienced significant improvements in sleep quality, with participants reporting they fell asleep faster, stayed asleep longer, and felt overall improvements in relaxation. Sleepbuds™ technology was found to be effective in reducing disturbances from noise sources such as snoring and urban sounds.
