The first-generation Bose QuietComfort Ultra Earbuds deliver industry-leading active noise cancellation paired with pioneering CustomTune audio personalization. Every time you wear them, an acoustic chime scans your inner ear to instantly optimize sound and noise suppression for your unique anatomy. Outfitted with Bose Immersive Audio spatial technology, these earbuds turn standard stereo into a wide, lifelike three-dimensional soundstage. Featuring a split-piece Fit Kit with 9 eartip/stability band configurations and a sweat-resistant IPX4 chassis, they offer up to 6 hours of continuous ANC playback per charge. Available directly from our Beirut showroom, this flagship personal audio package gives Lebanese audiophiles and creative professionals uncompromised acoustic perfection.
Experience an absolute standard in personal audio with the first-generation Bose QuietComfort Ultra Earbuds. Meticulously designed for professional media creators, discerning music enthusiasts, and high-frequency travelers who refuse to compromise on signal purity, these flagship earbuds redefine active noise cancellation (ANC). Moving past standard consumer earphones that flatten your music or leak ambient rumble during critical commutes, the QC Ultra Gen 1 utilizes a highly sophisticated proprietary hardware array to block out environmental distractions completely, surrounding you in a black hole of silence where only your media exists.
At the core of this engineering triumph is Bose’s revolutionary CustomTune technology. Every single time you place these earbuds into your ears, a brief chime sounds, initiating a physical acoustic scan. The internal feedback microphones analyze the unique physical geometry of your ear canal within milliseconds, automatically recalibrating both the sound profile and the noise-cancelling performance to match your ears perfectly. This results in incredibly deep, balanced low-end frequencies, rich mid-range textures, and shimmering highs, all tailored precisely to you. Coupled with Bose Immersive Audio—a cutting-edge spatialized processing engine—stereo tracks are pushed out of your head and into a wide, three-dimensional room speakers layout, creating a lifelike soundstage that mirrors a pair of premium studio monitors.
Craft your perfect listening environment while maintaining total physical comfort during multi-hour studio or travel sessions:
CustomTune Personalization: Automatically profiles your ear’s unique acoustic signature to optimize high-fidelity sound delivery and maximize external noise suppression.
Bose Immersive Audio Stage: Utilizes a custom digital signal processor (DSP) to spatialize standard stereo tracks, offering “Still” or “Motion” configurations for an expansive soundstage.
Progressive Fit Kit Architecture: Separates the silicone ear tips from the physical stability bands, providing 9 distinct size combinations to stay secure without creating painful pressure points.
Aware Mode with ActiveSense: Seamlessly balances transparency with safety, passing natural environmental sounds through while automatically suppressing sudden, loud noise spikes.
Advanced Bluetooth 5.3 Framework: Supports high-resolution streaming via Snapdragon Sound and Qualcomm aptX Adaptive codecs, delivering minimal audio latency and robust link stability.
Engineered to withstand demanding daily routines while keeping deep customization tools right at your fingertips:
Sweat-Resistant IPX4 Rating: Shields the internal acoustic transducers from unexpected water splashes and heavy sweat during high-intensity workouts or outdoor travel.
Responsive Touch-Capacitive Strips: Features integrated touch sensors along the outer stems for smooth volume adjustments, track skipping, or quick ANC mode switching.
Intelligent Wear Detection: Smart optical sensors pause your media playback automatically the moment an earbud is removed, saving battery life between tracks.
Bose Music App Integration: Unlocks a customizable 3-band equalizer (EQ), battery tracking, custom preset modes, and over-the-air firmware upgrades.
🎵 Acoustic Sealing Pro-Tip: To unlock the full depth of Bose’s legendary low-frequency performance, spend a few minutes testing different stability bands and ear tip sizes independently. A perfect physical seal prevents bass frequencies from leaking out and significantly increases the efficiency of the active noise cancellation microphones against low-frequency engine or traffic hums.

No, the Gen 1 charging case charges via USB-C exclusively. For wireless charging convenience, you can easily pair it with the optional Bose Wireless Charging Case Cover accessory, or upgrade to the newer Gen 2 model which has wireless charging coil circuitry built directly into the base housing.
“Still” mode is optimized for stationary listening (like sitting at a desk or on an airplane); it locks the audio soundstage in space directly in front of you, using built-in head-tracking sensors to shift the music if you turn your head. “Motion” mode is tailored for walking or commuting; it allows the spatialized 3D sound field to move smoothly alongside your physical travel trajectory.
Yes! While the Gen 1 model originally launched without this feature, Bose pushed out a comprehensive firmware update (Version 4.0.20 and newer). By updating your earbuds through the official Bose Music app, you unlock full Bluetooth Multipoint capabilities to switch seamlessly between your laptop and phone.
