Bose QuietComfort Ultra Headphones (2nd Gen)

New Upgrades & Audio Performance

Q: What is the difference between the 1st Gen and 2nd Gen QC Ultra Headphones? A: The 2nd Gen models introduced several key upgrades, including lossless USB-C audio (allowing you to listen to high-res audio via cable while charging), an upgraded Bluetooth 5.4 chip for better connectivity, an extended 30-hour battery life, and a new Cinema Mode specifically optimized for movies and TV. They also feature a slightly refined adaptive noise-canceling algorithm for better mid-to-high frequency blocking.

Q: What is Cinema Mode? A: Cinema Mode is a new addition to Bose Immersive Audio. It applies spatialized, 3D audio to video content but uses a different equalization than the standard music modes. It reduces reverb and sharpens dialogue so voices remain clear and focused while keeping sound effects layered and immersive.

Q: Can I use them wired for lossless audio? A: Yes! A major upgrade for the 2nd Gen is the ability to use a USB-C to USB-C connection directly to your computer or Android phone. This acts as a digital audio interface, allowing you to listen to zero-latency, high-fidelity 24-bit/48kHz lossless audio while the headphones charge simultaneously. You can also still use the included 2.5mm to 3.5mm analog cable.

Q: Do they support high-resolution wireless audio? A: Yes. They are Snapdragon Sound certified and support the aptX Adaptive codec, which allows for high-resolution, low-latency streaming when paired with compatible Android devices.

Noise Cancellation & Modes

Q: Can I completely turn off Active Noise Cancellation (ANC)? A: Yes, unlike some older Bose models, the 2nd Gen allows you to customize your listening modes in the Bose app, giving you the ability to lower the ANC or adjust the transparency levels to your exact preference.

Q: What are the primary listening modes? A: Out of the box, they feature:

• Quiet Mode: Maximum noise cancellation.

• Aware Mode: Full transparency to hear your surroundings naturally, featuring ActiveSense to instantly dampen sudden loud noises.

• Immersion Mode: Combines full noise cancellation with spatialized Bose Immersive Audio.

Connectivity & App Usage

Q: Do they support Bluetooth Multipoint? A: Yes. With upgraded Bluetooth 5.4, you can connect the headphones to two devices simultaneously (e.g., a phone and a laptop) and seamlessly switch between audio sources without having to disconnect and reconnect.

Q: Do I need the Bose Music app to use them? A: No, they will work natively via Bluetooth right out of the box. However, the app is highly recommended to access software updates, adjust the EQ (bass, mid, treble), customize the shortcut button, and manage your immersive audio and ANC settings.

Fit, Controls, and Design

Q: Are they comfortable for long flights or workdays? A: Yes. Weighing only 250 grams (8.8 oz), they are among the lightest premium ANC headphones on the market. They feature deep, plush protein-leather ear cushions and a low-pressure headband designed for zero fatigue during extended wear.

Q: How do you control volume and playback? A: The right earcup features a physical multi-function button for play/pause and track skipping, a Bluetooth pairing/power button, and a capacitive touch strip—simply slide your finger up or down the strip to adjust the volume.

Q: Are they waterproof? A: No. They are not IP-rated for water or sweat resistance. While they can handle a light drizzle, they are not designed for intense workouts or heavy rain.

Q: Do they fold up? A: Yes, the aluminum yokes fold inward, allowing the headphones to collapse neatly into the included hard-shell carrying case for easy travel.

Battery & Charging

Q: How long does the battery last? A: You can expect up to 30 hours of continuous playback with ANC turned on (a 6-hour increase from the 1st Gen). If you use Bose Immersive Audio, the battery life drops to about 23 hours due to the heavy audio processing.

Q: How fast do they charge? A: A quick 15-minute charge will give you up to 3 hours of listening time. A full charge from 0 to 100% takes about 3 hours via USB-C.

Q: Do they turn off automatically when I take them off? A: Yes. They feature smarter on-head detection. When you take them off, the music auto-pauses. If left off your head, they enter an automatic Bluetooth standby and deep-sleep low-energy mode to preserve battery life.
