Bose QuietComfort Ultra Headphones: Advanced Noise-Cancelling Excellence

Quiet Mode (Default)

By default, the headphones power on in Quiet Mode, delivering maximum noise cancellation for total focus. It’s perfect for flights, offices, or any situation where you want complete silence.

Aware Mode with ActiveSense

In Aware Mode, ambient sounds are blended with your audio to keep you connected to your surroundings. With ActiveSense technology, sudden loud noises are automatically softened, ensuring a smooth and safe listening experience in dynamic environments.

Custom Mode

Custom Mode lets you personalize noise cancellation based on your specific needs.

• Immersion Mode: Delivers enhanced noise isolation for deep focus, perfect for meditation or creative work.
• Wind Mode: Reduces wind interference during outdoor activities for clear, uninterrupted listening.

Default Favorite Modes & Customization

The QuietComfort Ultra comes with three default favorite modes: Quiet, Aware, and Immersion. You can easily toggle between these modes using the Multi Function button. If you want to personalize or reset the modes, use the Bose Music App to adjust settings and save your preferences.

Personalized Sound Calibration

CustomTune technology adapts the audio output to your unique ear profile, ensuring every detail is clear and every tone is rich. This feature guarantees a tailored listening experience, whether you’re enjoying music, podcasts, or calls.

High-Fidelity Audio Drivers

Equipped with 40mm precision drivers, the QuietComfort Ultra delivers high-resolution sound with balanced highs, rich mids, and deep, punchy bass. The result is studio-grade audio performance for audiophiles and casual listeners alike.

Advanced Qualcomm Snapdragon Sound Technology Suite

The QuietComfort Ultra headphones leverage Qualcomm’s Snapdragon Sound Technology Suite for superior audio performance. Key features include:

• aptX Adaptive: Provides lossless audio and low-latency performance, ideal for high-quality streaming on compatible Android devices.
• AAC Codec: Ensures consistent high-quality audio for both Apple and Android users.
• SBC Codec: Offers reliable and stable audio performance across various devices.

Compatibility Considerations for aptX Adaptive

While the aptX Adaptive codec enhances sound quality, it is supported only by some Android smartphones. Compatibility depends on the manufacturer’s implementation of aptX licensing. For instance, some flagship models from Samsung and Google may not fully support aptX, potentially limiting its benefits on those devices.

360-Degree Soundscapes

Bose QuietComfort Ultra headphones take audio immersion to the next level with spatial audio technology, delivering 360-degree soundscapes that envelop you. Whether you’re watching movies, gaming, or streaming music, the sound feels vivid and lifelike, creating a sense of being at the heart of the action.

Immersive Audio Modes

These headphones come with two distinct immersive audio modes to adapt to your activity:

• Still Mode: Designed for stationary use, this mode ensures precise and consistent sound placement, ideal for movies and music where sound directionality matters.
• Motion Mode: Perfect for active scenarios, this mode dynamically adjusts the audio to your movements, keeping you immersed even as you move.

Advanced IMU Chip for Precision

At the core of the immersive experience is the Inertial Measurement Unit (IMU) chip, which tracks head movements with remarkable accuracy. This chip ensures that the spatial audio adjusts in real time, keeping the soundscapes perfectly aligned no matter how you move.

The Bose QuietComfort Ultra Headphones provide a variety of listening modes tailored to different environments and user needs. Here’s a detailed overview of the modes, how to switch between them, and how to manage your preferences.

Available Listening Modes

• Quiet Mode: The default mode when the headphones power on, offering full noise cancellation to block out distractions. Ideal for use in noisy environments like commutes, offices, or flights.
• Aware Mode with ActiveSense: Keeps you aware of your surroundings by allowing external sounds to pass through. ActiveSense technology automatically adjusts to reduce sudden loud noises while maintaining transparency, ensuring an uninterrupted yet safe listening experience.
• Custom Mode: Allows you to personalize noise cancellation and sound settings to match your environment. For example, you can create a “Wind Block” mode to minimize wind interference during outdoor activities. Custom modes can be created and saved using the Bose Music App, providing up to seven unique configurations.
