when it is unused for long periods of time.

X Do not use the product near water and do not expose it to rain or moisture to

reduce the risk of fire or electric shock.

Preventing damage to the product and malfunctions

X Always keep the product dry and do not expose it to extreme temperatures

to avoid corrosion or deformation. The normal operating temperature is from 0 to 40°C/32 to 104°F.

X Use only attachments/accessories/spare parts supplied or recommended by

Sennheiser.

X Clean the product only with a soft, dry cloth. X Only use the product in environments where Bluetooth® wireless transmis-

sion is permitted.

The MOMENTUM Wireless (M2 OEBT)

Bluetooth

The MOMENTUM Wireless (M2 OEBT) headphones comply with the Bluetooth technology 4.0 standard and are compatible with all Bluetooth 1.1, 1.2, 2.0, 2.1,

3.0 and 4.0 devices with the following profiles:

• Headset Profile (HSP) 1.2 - provides the basic functionalities used by the headphones to interact with a Bluetooth smartphone.

• Hands-Free Profile (HFP) 1.6 - provides extra functionalities as compared to the HSP. If a function, such as voice control, is not supported by the HSP profile, the HFP takes place.

• Audio/Video Remote Control Profile (AVRCP) 1.5 - used to control music on the Bluetooth device from the headphones (play, pause, skip music track, etc.).

• Advanced Audio Distribution Profile (A2DP) 1.3, supporting aptX® - used by a Bluetooth device to stream high-quality stereo music to the headphones.

• Device ID Profile (DIP) 1.3 - by the headphones to be identified, such as by its manufacturer, product ID, product version, etc.

NFC

Near Field Communication (NFC) is a short-range wireless technology that enables connection and communication between NFC-capable electronic devices by placing them near one another or with a single touch.

VoiceMax

VoiceMax™ dual microphone technology filters away the background noise. 2 microphones work in synergy; one to emphasize your voice, and the other to remove the ambient noise.

NoiseGard

The NoiseGard™ hybrid Active Noise Cancellation system is a combination of 2 noise-cancellation systems composed of a total of 4 microphones. Two microphones with openings to the outside of the headphones work as a Feed-Forward active noise cancellation system that reduces noise in the high-frequency band, while the other two microphones inside the headphones work as a Feed-Back active noise cancellation system that reduces noise in the low-frequency band. The combination of these 2 microphone systems results in a broad reduction in noise covering a wider band of frequencies.

aptX®

With aptX® audio coding, you can be assured of crisp, pure and full stereo sound. It allows you to not only hear, but experience and feel the audio as it was intended. Utilizing aptX®, Bluetooth technology can now offer wireless audio quality that is indistinguishable from the highest quality wired connection.

Getting started

Charging basics

A complete charging cycle takes about 3 hours. Before using the headphones for the first time, charge their rechargeable battery for a complete charging cycle without interruption.

When the battery is almost empty or when the headphones are being charged, the LED lights up or flashes as indicated in the table below and a voice prompt announces the charge condition of the battery. When the battery charge drops to a low level, a voice message prompts you to recharge the headphones to avoid call and music disruptions.

It is recommended to charge the headphones using only the supplied USB cable. If you are charging using an external USB-power adapter, it is recommended to use an adapter with an output rating of 500 mA or higher.

Pairing the headphones

AUTION

Danger of malfunction!

The transmitted radio waves of mobile phones can impair the operation of sensitive and unprotected devices.

X Only make calls with the headphones in locations where Blue-

tooth wireless transmission is permitted.

To pair your headphones with a Bluetooth device, you can either use the Near Field Communication (NFC) or the Bluetooth search function. In order that a connection between the headphones and a Bluetooth device can be established, Bluetooth must be activated, whether you use Bluetooth or NFC pairing.

The M2 OEBT headphones comply with the Bluetooth 4.0 standard. In order that data can be transmitted wirelessly using Bluetooth technology, you have to pair your headphones with compatible Bluetooth devices that support the following profiles:

X Hands Free Profile (HFP) X Headset Profile (HSP) X Audio/Video Remote Control Profile (AVRCP) X Advanced Audio Distribution Profile (A2DP) X Device ID Profile (DIP)

When you switch the headphones on, they automatically try to connect to the last two connected Bluetooth devices. The headphones can save the connection profiles of up to eight Bluetooth devices with which they have been paired.

If you pair the headphones with a ninth Bluetooth device, the saved connection profile of the least used Bluetooth device will be overwritten. If you want to re-establish a connection with the overwritten Bluetooth device, you have to pair the headphones again.

You can easily pair and connect your wireless headphones with your smartphone if the device supports the Near Field Communication (NFC) technology.
