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.
