Features

Overview: The Sennheiser SPORT True Wireless in-ear headphones (CX200TW1) are two individual ear buds with no connecting wires. They connect to
your smartphone or tablet (and to each other) via Bluetooth. Six pairs of
silicone ear tips (3 closed, 3 open) and 4 pairs of ear fins are included for a secure and comfortable fit. The SPORT True Wireless headphones come with a charging case for storage, and for recharging
the batteries.

Drivers: The SPORT True Wireless features 7mm TrueResponse dynamic transducers that deliver high-fidelity sound with clear treble, natural midrange, and deep bass. You can tailor the sound using the equalizer found in the Sennheiser Smart Control app, available for iOS and Android devices.

Bluetooth 5.2: The SPORT True Wireless headphones feature Bluetooth
version 5.2 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: 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).

Designed for Sport: The SPORT True Wireless headphones are designed to withstand rigorous activity. The earbuds feature a splash, dust, and sweat-resistant design with an IP54 rating, so you can work out anywhere, even in the rain or snow, without worry. The silicone ear fins tuck behind the folds in your outer ear to help hold the earbuds in place, even during your workout. The fins come in four sizes (N, S1, S2, S3) to help you find the most secure and comfortable fit.

Adaptable Acoustics: The Adaptable Acoustics feature lets you choose the level of immersion or awareness you desire when wearing the headphones. Two types of ear tips are included with the headphones to match the special Adaptable Acoustic EQ modes in the Smart Control app. For an immersive listening experience, you can choose the Focus mode in the app, and install the special Closed ear adapters (with the black cross inside) onto the ear buds. The Focus mode and closed ear adapters minimize your awareness of your surrounding to help you focus on your music or your task. The Aware mode, along with the Open ear adapters (with the blue marking inside), helps you to hear sounds around you. This helps keep you safe when walking or running in public or in high traffic areas.

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 3 times activates the voice assistant for you to make a request or ask a question. You can also activate voice dialing through the voice assistant.

Voice Prompts: The ear buds output voice prompts to confirm events or headphone status. These voice prompts include "Power on," "Power off," "Connected," "No connection," "Pairing," "Pairing successful," "Pairing failed," "Recharge headset," "Call rejected," or "Call ended." In the Smart Control app, you can change the language of the voice prompts, choose between voice prompts and beep sounds, or deactivate some of the status messages.

Rechargeable Batteries: The SPORT True Wireless headphones are powered
by built-in 3.7VDC Lithium-Ion rechargeable batteries. Each earbud\’s
has a 55-72 mAh battery, while the charging case has a 400-420 mAh 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, 600 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 9 hours
playback. The charging case provides enough stored power to charge the earbuds approximately 2 additional times, to extend the playback time to 27 hours.

Phone/Music Controls: Controls for music playback and phone
call functions are located on separate earbuds. Both earbuds are equipped with touch-sensitive controls. The left earbud controls Volume Down (hold), and
music playback functions Play/Pause (1x) and Previous Track (2x). The right
earbud controls Volume Up (hold), Voice Assistant (3x), Play/Pause (1x), and Next Track (2x). For phone call functions, you can use either ear bud to accept (1x), end (1x), or reject (2x) calls. When you\’re on a call and another call comes in, you can tap either earbud to accept (1x) or reject (2x) the incoming call.

Microphones: Each SPORT True Wireless earbud is equipped with a dual microphone system in a beamforming array (4 mics total). This pickup pattern helps to reduce ambient noise. The microphones have a 100Hz to 10kHz frequency response.

Smart Control App: In addition to the on-board controls, the
SPORT True Wireless in-ear headphones can be controlled by Sennheiser\’s
Smart Control app for Android and iOS devices. The app lets you customize the ear buds\’ on-board controls as you desire. An easy-to-use 3-band EQ, with preset 6 EQ settings (Rock, Pop, Dance, Hip Hop, Classical, Movie), help you personalize the sound. The Adaptable Acoustics feature in the app lets you select the level of immersion or awareness of your surroundings by switching between Focus and Aware modes. Firmware updates for the earphones are
also available through the app. The Smart Control app is compatible with iOS
devices running version 13.0 and later, and Android devices with version 8.0 and
up.
