Bose QuietComfort Ultra Earbuds

Product Description

Headline: Sound Just Got Real. Experience the Bose QuietComfort Ultra Earbuds.

Step into a new dimension of listening with the Bose QuietComfort Ultra Earbuds. Designed for the ultimate audiophile, these flagship true wireless earbuds combine Bose’s legendary Active Noise Cancellation (ANC) with groundbreaking Bose Immersive Audio. By spatializing what you hear, Immersive Audio takes your music out of your head and places it right in front of you, creating a lifelike, multi-dimensional soundstage that feels like a live performance.

Personalization is at the heart of the Ultra experience. Powered by CustomTune technology, these earbuds automatically analyze the unique shape of your ear canal every time you wear them, instantly optimizing both the sound profile and the noise cancellation for your specific ears. Shut out the world entirely with Quiet Mode, stay connected to your surroundings with Aware Mode, or combine maximum noise cancellation with spatial audio using Immersion Mode.

Comfort meets durability with the included Bose Fit Kit, featuring nine possible combinations of soft silicone ear tips and stability bands to ensure a secure, slip-free, and comfortable fit all day long. Powered by advanced Bluetooth 5.3, Snapdragon Sound certification, and aptX Adaptive codec support, you are guaranteed a high-resolution, drop-free connection.

Whether you are commuting, working out, or relaxing, the Bose QC Ultra Earbuds keep up with your lifestyle. Enjoy up to 6 hours of continuous listening, crystal-clear phone calls powered by an advanced AI-noise-rejecting microphone system, and an IPX4 water-resistant build.

• Bose Immersive Audio & Sound Quality

  1. What is Bose Immersive Audio? A: Immersive Audio is Bose’s proprietary spatial audio technology. It takes the music out of your head and creates a three-dimensional soundstage right in front of you, making it feel like you are listening to a live performance. It works with any stereo audio source.

  2. What is the difference between the “Still” and “Motion” Immersive Audio settings? A: Still mode keeps the audio fixed in one place, which is ideal when you are sitting down. Motion mode allows the audio to move with you as you turn your head, making it perfect for when you are walking or commuting.

  3. What are the three main listening modes? A: The earbuds feature Quiet Mode (maximum noise cancellation), Aware Mode (full transparency to hear your surroundings), and Immersion Mode (maximum noise cancellation combined with Bose Immersive Audio).

  4. How does CustomTune technology work? A: Every time you place the earbuds in your ears, a built-in microphone plays a chime to map your ear canal’s acoustic shape. It then instantly adjusts both the audio equalization and the Active Noise Cancellation (ANC) to perfectly suit your ears.

  5. Can I adjust the Bass and Treble? A: Yes. You can use the Adjustable EQ feature in the Bose Music app to manually customize the bass, mid-range, and treble levels, or select from pre-made audio profiles.

  Connectivity & Technology

  6. Do the QC Ultra Earbuds support high-resolution audio? A: Yes. Unlike previous generations, the Ultra Earbuds are Snapdragon Sound certified and support the aptX Adaptive codec. This allows for lossless, high-resolution audio streaming when connected to compatible Android devices.

  7. Do they support Bluetooth Multipoint? A: Yes. They feature true multipoint connectivity, allowing you to connect to two devices (like a laptop and a smartphone) simultaneously and seamlessly switch between them without needing to disconnect.

  8. Can I use just one earbud at a time? A: Yes. You can use either the left or the right earbud independently for listening to music or taking phone calls, while the other earbud remains charging in the case.

  9. Do I need the Bose Music app? A: While you can connect via basic Bluetooth, the app is highly recommended. You need it to toggle Immersive Audio, adjust the EQ, manage Bluetooth connections, customize touch controls, and download firmware updates.

  10. What Bluetooth version do they use? A: They use Bluetooth 5.3, which provides a highly stable connection, improved power efficiency, and a range of up to 30 feet (9 meters).

  Fit, Controls & Durability

  11. What is included in the Bose Fit Kit? A: The Fit Kit separates the earbud seal into two parts: three pairs of silicone ear tips (Small, Medium, Large) and three pairs of stability bands (Size 1, 2, 3). This provides nine possible combinations per ear to ensure a secure, personalized fit.

  12. How do I control the volume? A: You can adjust the volume directly on the earbuds by simply swiping up or down on the capacitive touch strip located on the stem of either earbud.

  13. Can I customize the touch controls? A: Yes. Using the Bose Music app, you can customize the “Touch & Hold” shortcut on each earbud to perform different actions, such as toggling Immersive Audio, switching listening modes, or accessing your phone’s voice assistant.

  14. Are they suitable for working out? A: Yes. They have an IPX4 rating, making them resistant to sweat and water splashes. They are perfect for the gym or light rain, but they cannot be submerged in water.

  15. How do I clean the earbuds? A: Remove the silicone tips and bands and wash them with mild soap and water (ensure they are completely dry before putting them back). Wipe the earbuds and the charging contacts with a soft, dry cloth. Never push objects into the speaker mesh.

  Battery, Charging & Troubleshooting

  16. How long does the battery last? A: You get up to 6 hours of listening time on a standard charge. However, if you have Bose Immersive Audio turned on, the battery life drops to about 4 hours due to the heavy audio processing.

  17. Does the case support wireless charging? A: No. Out of the box, the case only charges via a USB-C cable. However, Bose sells an optional Wireless Charging Case Cover accessory separately that you can slip over the case to enable Qi wireless charging.

  18. How fast do the earbuds charge? A: A quick 20-minute charge with the earbuds in the case will provide up to 2 hours of listening time. A full charge for the earbuds takes roughly 2 hours, and the case takes about 3 hours to fully recharge.

  19. How do I check the battery life? A: A voice prompt will announce the battery level every time you put the earbuds in. You can also check the exact battery percentage for both the earbuds and the case inside the Bose Music app.

  20. How do I factory reset the Ultra Earbuds? A: If you experience connectivity or audio bugs, place both earbuds in the charging case with the lid open. Press and hold the button on the back of the case for about 20 seconds until the LED light blinks white, then blinks amber, and finally turns white again. Your earbuds are now reset.
