The elegant new, next-generation Modus 6450 wraps the best in functionality, fun and fashion in a sleek crystal-blue form factor. The Modus is designed for consumers looking for a conventional noise-cancelling Bluetooth headset with the capability to stream stereo audio. It can be worn as a mono-style headset for placing and receiving calls and readily transforms into a stereo Bluetooth headset when connected to the included stereo ear bud headset for an enhanced audio experience. The 6450 improves on its predecessor, the HM3500, with a premium headphone set, voice command functionality, and EQ settings. Rather than just simple voice prompts, the Modus 6450 implements voice commands and EQ settings through a separate Voice Command Button on the headset, distinguishing it from most competitors that must use a multifunction button for voice command start. The Modus supports a multitude of advanced noise cancellation features and a dual microphone design to separate the user's voice from the surrounding background noise. When enjoying rich, full-fidelity Bluetooth stereo while also connected to a phone, the Modus will gently mute the stereo audio, allowing the user to answer or initiate phone calls and seamlessly restores its settings when the call is complete. The user can also stream full fidelity audio and enjoy the rich sound through the single earpiece of the Bluetooth headset. The Modus 6450 is compatible with its own specially-designed Android application, the Samsung Bluetooth FreeSync equipped with several features that set it apart from other applications, including EQ settings for stereo mode, LED settings, and language selection. The FreeSync application allows for text-to-speech messaging and caller ID services and the ability to enable or disable Bluetooth headset functions through the application.
