Features

Overview: The Sennheiser Momentum Sport True Wireless in-ear headphones are two individual ear buds with no connecting wires. They connect to your smartphone or tablet (and to each other) via Bluetooth version 5.2. These Sport headphones can track your heart rate and body temperature. Three pairs of transparent silicone ear tips (S, M, L), and four pairs of silicone ear fins (N, S, M, L) are included for a secure and comfortable fit. The headphones are equipped with Adaptive Active Noise Cancellation (ANC) to shut out the outside world while you listen to your music or phone call. The Momentum Sport True Wireless headphones come with a charging case for storage, and for recharging the earbuds.

Drivers: The True Wireless ear buds feature 10mm dynamic drivers that reproduce a wide frequency range and provide the Sennheiser Sport sound. You can tailor the sound of the earphones through the equalizer found in the Sennheiser Smart Control app, available for iOS and Android devices.

Bluetooth 5.2: The Momentum Sport in-ear headphones feature Bluetooth version 5.2 which pairs to your phone or audio device in seconds. The ear buds can pair with up to six Bluetooth devices, and make up to two active connections simultaneously (multi-point). You can make and receive phone calls and stream audio wirelessly in a range of up to 33' (10 meters), depending upon environmental conditions. The headphones have a maximum of 10mW of output power, and have the following profiles: HFP, AVRCP, and A2DP. The headphones support aptX and aptX Adaptive, as well as AAC (advanced) and SBC (standard) codecs. Either the right or left ear bud can be used alone, if desired.

Active Noise Cancelling (ANC): Each ear bud is equipped with three microphones, two on the outer panel and one on the inner panel, for Active Noise Cancellation. Tapping the left ear bud three times activates (and deactivates) ANC. The noise cancellation is "adaptive," with the maximum noise reduction occurring in a noisy environment, and the minimum in a quiet environment. There is also an "Anti-Wind" feature to reduce ambient noise caused by windy conditions. The Transparency Mode lets you hear ambient sounds or have a short conversation without having to remove the ear buds. In addition to the touch controls on the ear buds, you can turn on or off ANC and Transparency Mode in the Smart Control app.

Voice Assistants: The ear buds are compatible with the voice assistant that is native to your smartphone, such as Siri or Google Assistant. Tapping the right ear bud twice activates the voice assistant for you to make a request or ask a question. You can also activate voice dialing through the voice assistant.

Rechargeable Batteries: The Momentum Sport True Wireless headphones are powered by built-in Lithium-Ion rechargeable batteries. Each ear bud has a 3.8V / 72 mAh battery, while the charging case has a 3.6V / 820mAh-900mAh battery. The complete charging cycle of the charging case and earphones is approximately 1.5 hours. A 10-minute Quick Charge provides about 1 hour of playback time. The battery in the charging case charges via USB-C power (5V, 1000 mA) using the supplied cable from a laptop, an AC-powered USB charging port, or a mobile 12-volt USB charging port. The charging case is also compatible with Qi wireless charging (charging time is slightly longer). Fully-charged batteries in the ear buds provide approximately 6 hours playback. The charging case provides enough stored power to charge the ear buds 3 additional times, to extend the playback time to 24 hours.

Phone/Music Controls: Touch Panel controls for music playback and phone call functions are located on the outside of both ear buds. Various touch patterns can also activate ANC, Transparency, Voice Assistant, and Volume.

Smart Pause: The ear buds automatically detect when they are being worn, or when they are removed from the ear. When you remove one or both of the ear buds from your ear, the Smart Pause function pauses the music automatically. The music automatically resumes if you reinsert it within a minute. You can turn this feature on or off in the Smart Control app.

Voice Prompts: The ear buds provide a voice prompt to confirm certain functions and conditions. Voice Prompts include subjects such as Power ("Power On", "Power Off"), Bluetooth ("Connected", "Pairing", "Pairing cancelled/successful/failed"), Battery Status ("Battery Status" (percent), "Recharge headset"), Phone Calls ("Call Rejected", "Call Ended"), and Volume ("Volume Minimum", "Volume Maximum"). On the Smart Control app, you can change the language of the prompts (8 languages available), choose between voice prompts and beep sounds, or deactivate the status messages.

Health Data Collection: The Momentum Sport earbuds offer the option of measuring your heart rate and body temperature while you work out. The sensors are located in the sound channel of the left earbud. The collected data can be viewed in the Smart Control app. A secondary fitness app, such as Polar Flow®, that supports the use of the health values can help you use the data more effectively. Heart rate tracking can help you determine the intensity of your training and track your fitness progress. It can also help you avoid overexertion and injury. Monitoring your body temperature during workouts helps you to avoid heat-related illness, such as heat cramps, heat exhaustion, and heat stroke.

Smart Control App: In addition to the on-board controls, the Momentum Sport True Wireless in-ear headphones can be controlled by Sennheiser's Smart Control app for Android and iOS devices. The app lets you personalize and enhance the sound to suit your current mood with the easy-to-use equalizer. The Transparent Hearing function lets you adjust how much of your surroundings you can hear while wearing the ear buds. You can shut out your surroundings if you want to concentrate on your music, or allow ambient sounds in if you need to listen for announcements, or carry on a conversation with another person, without having to remove the ear buds. Firmware updates for the earphones are also available through the app. The Smart Control app is compatible with iOS devices (iPhone, iPod touch) running version 13.0 and later, and Android devices with version 8.0 and up.
