The True Wireless 2 headphones are crafted to provide natural, high-quality sound with 7mm dynamic drivers and a built-in equalizer that lets you personalize the sound to your tastes. Audio is streamed to the headphones via Bluetooth-compatible mobile devices, such as a smartphone or tablet. When paired with a smartphone, you can also use the True Wireless 2 headphones for hands-free calling and interacting with Google Assistant or Siri. However you use them, you get up to 7 hours of power and an additional 21 hours via the included charging storage case.


Drivers: The True Wireless 2 features custom-made 7mm dynamic drivers that reproduce a wide frequency range and unparalleled sound. From the crystal clear highs to the natural midrange and low bass, you can enjoy your favorite music from any genre. 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 5.1: The Momentum True Wireless 2 headphones feature Bluetooth version 5.1 which pairs to your phone or audio device in seconds. 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: Headset Profile (HSP), Hands-Free Profile (HFP), Audio/Video Remote Control Profile (AVRCP), and Advanced Audio Distribution Profile (A2DP). If your audio source supports aptX or AAC, music is automatically played in high audio quality. Otherwise, the headphones will play in standard audio quality (SBC). The right ear bud is the master, and controls the Bluetooth connection to the smartphone and to the left ear bud. This allows you to listen to music or phone calls with the right ear bud only, but not the left one alone.

Voice Assistants: The ear buds are compatible with the voice assistant that is activated to your smartphone, such as Siri or Google Assistant. Tapping the right ear bud once 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 True Wireless 2 headphones are powered by built-in 3.7VDC Lithium-Ion rechargeable batteries. Each earbud's has a 55-60 mAh battery, while the charging case has a 600mAh battery. The complete charging cycle of the charging case and earphones is approximately 1.5 hours. A 10-minute Quick Charge provides about 1.5 hours of playback time. The battery in the charging case charges via USB-C power (5V, 650 mA) using the supplied cable from a laptop, an AC-powered USB charging port, or a mobile 12-volt USB charging port. Fully-charged batteries in the earbuds provide approximately 7 hours playback. The charging case provides enough stored power to charge the earbuds 3 additional times, to extend the playback time to 28 hours.

Phone/Music Controls: Controls for music playback and phone call functions are located on separate earbuds. Both earbuds are equipped with 5/8" diameter touch control panels. The left earbud controls Volume Down, and music playback functions Play/Pause, Next Track, and Previous Track. The right earbud controls Volume Up, Voice Assistant, Voice Dialing, Active Noise Cancellation, and Transparent Hearing. For phone call functions, you can use either ear bud. Touching both control panels simultaneously lets you pair and connect the earbuds to your Bluetooth mobile device.

Smart Pause: The ear buds automatically detect when they are being worn, or when they are removed from the ear. When you remove one of the earbuds 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.

Microphones: The True Wireless 2 earbuds are equipped with a beam-forming, noise cancellation, dual microphone system. Multiple microphones distributed between the two earbuds are used for both phone calls and noise cancellation.

Voice Prompts: The earbuds 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.

Smart Control App: In addition to the on-board controls, the Momentum True Wireless 2 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 Emotional Equalizer. The Transparent Hearing function lets you adjust how much of your surroundings you can hear while wearing the earbuds. 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 earbuds. Firmware updates for the earphones are also available through the app. The Smart Control app is compatible with iOS devices running version 12.0 and later, and Android devices with version 7.0 and up.
