Features

Overview: The Bose Ultra Open Earbuds feature a unique style and fit that doesn\’t block your ears. Bose\’s proprietary OpenAudio technology lets you hear the rich audio while staying connected to the outside world. The true wireless earbuds are inspired by ear cuff jewelry and hook securely around the outer portion of your ear. The lightweight grip is strong enough for the earbuds to stay put, but comfortable enough so you can wear them all day. The Ultra Open Earbuds come with a sleek charging case and a USB charging cable.

OpenAudio Technology: Bose\’s OpenAudio technology provides a rich audio experience that only you can hear. Your audio remains private, as almost no sound is heard by others around you. The earbuds are not inserted into the ear canal, but are positioned near it, so you can still hear sounds from your surroundings. The Ultra Open Earbuds direct audio into the ear canal while the proprietary technology minimizes sound leakage in other directions.

Bluetooth 5.3: The Ultra Open Earbuds feature the latest Bluetooth version (Bluetooth 5.3). They support A2DP, HFP, AVRCP, and BLE profiles, and operate at a range of up to 30 feet from your paired device. The earbuds support SBC, AAC, and aptX adaptive codecs. On Android devices certified with Snapdragon Sound, you\’re assured of getting the best audio quality and the lowest latency with the Ultra Open Earbuds. Android users can also enjoy simple, fast pairing with Google Fast Pair. When you turn on the headphones, a Google Fast Pair pop-up window appears for rapid setup of the device. The Bose Ultra Open Earbuds are compatible with your device\’s native voice assistant.

aptX Adaptive: AptX Adaptive helps to maintain the best sound quality and provide a solid wireless connection. When the Bluetooth connection is less than ideal, the earbuds will slightly lower the audio quality in order to obtain a stronger wireless connection to your device, thus avoiding audio dropouts. When you have a strong wireless connection, the Ultra Open Earbuds boost the sampling rate from 44.1kHz to 48kHz for higher audio quality and lower latency.

Immersive Audio: Bose\’s new Immersive Audio makes your music sound as if it\’s coming from beyond the earbuds. It gives it a wider sound stage in the front and on the sides for a more spacious listening experience. You can choose from two Immersive Audio Settings. The Motion setting makes your audio sound as if you\’re listening to two stereo speakers in front of you, and the sound stays in front of you, even when you turn your head. This setting works best when you are moving or have to turn your head or look down frequently. The Still Setting sounds like two stereo speakers that don\’t move with you–they stay in place. This setting is best suited to when you are sitting stationary. Immersive Audio shuts off temporarily when a phone call comes in. You can choose between two listening modes: Stereo Mode (Immersive Audio Off) and Immersive Audio Mode. Both modes can be customized in the Bose Music app.

Bose Music App: The Bose Music App helps you to enjoy your Ultra Open Earbuds even more. The app aids you in setting up and controlling your earbuds from any smartphone or tablet. In the app, you can select an action, such as checking the battery level or skipping a track, and save it as a Shortcut. The Auto Volume feature dynamically adjusts the volume of your music as the noise level of your environment changes, making sure you can always hear your music at the same level relative to the background. The buttons on the earbuds can be customized to trigger specific functions or switch devices the earbuds are connected to. The Bose Music app makes pairing easier and faster, lets you choose your voice prompt language, and manage your earbud settings. You can use the app to easily browse your favorite music sources. An equalizer in the app lets you adjust the bass, midrange, and treble to suit your listening preferences. The app is available from the App Store for iPhone, iPad, and iPod touch running iOS 15 or later, and from Google Play for Android devices (version varies with device).

Microphones: The Ultra Open Earbuds are equipped with four microphones, two on each earbud. The microphones are used for phone calls and for voice commands when connected to your phone\’s native voice assistant.

Water/Sweat Resistance: The Bose Ultra Open Earbuds have an IPX4 rating for their resistance to sweat, weather, and splashing water from any angle. The Charging Case is IPX1-rated, and is resistant to water and sweat that may remain on the earbuds after use, or gentle vertical rainfall. The earbuds and charging case are not waterproof, and should not be submerged.

Onboard Controls: Each earbud has a single, upward-facing button on the barrel-shaped part that rests behind your ear. The buttons control both phone calls and music playback:
