        Overview

        Aurum Finish & Premium Aesthetics

        The Noise Master Buds 2 in Aurum colour are designed to deliver a refined and modern visual appeal. This finish gives the earbuds a sleek and understated look, making them suitable for both casual and professional settings. The signature vinyl-disc inspired charging case adds a distinctive touch, setting it apart from conventional designs. The smooth contours and compact build ensure that the earbuds not only look premium but also feel comfortable and secure during extended use.

         

        Sound By Bose for Balanced Audio

        At the core of the listening experience is Sound by Bose tuning, which prioritizes clarity and balance across frequencies. The earbuds are equipped with 10mm dynamic drivers that produce a rich yet controlled sound profile. Bass is present but not overpowering, mids remain natural, and highs are crisp without harshness. This makes the earbuds versatile for different content types, including music, podcasts, movies, and calls, ensuring a consistent and refined audio experience.

         

        Spatial Audio & Head Tracking

        The inclusion of 360° spatial audio with head tracking enhances immersion by creating a sense of depth and direction in sound. Powered by a built-in motion sensor, the audio adjusts dynamically as the user moves their head. This creates a more engaging experience, especially when watching videos or playing games, where sound positioning plays an important role in realism.

         

        Active Noise Cancellation & ENC

        The earbuds feature Active Noise Cancellation (ANC) that reduces unwanted background noise, allowing users to focus on their audio. Whether in a busy environment or during travel, ANC helps create a more controlled listening space. Additionally, the 6-microphone Environmental Noise Cancellation (ENC) system improves call clarity by filtering ambient noise and enhancing voice pickup, ensuring clearer communication.

         

        Smart Controls & App Features

        The earbuds come with intuitive touch controls that allow users to manage playback, calls, and volume with ease. They also support voice assistants, enabling hands-free operation. Through the Noise companion app, users can access custom EQ settings, firmware updates, and device tracking features, allowing for a more personalized and convenient user experience.

         

        Battery Life & Everyday Reliability

        Designed for long usage, the earbuds offer up to 30 hours of total playback with the charging case. Fast charging support ensures that even a short charge provides hours of listening time. With an IPX5 water resistance rating, the earbuds are protected against sweat and light splashes, making them suitable for workouts and daily activities. These earbuds deliver a balanced combination of style, sound, and smart functionality. The Aurum finish enhances their premium appeal, while features like Bose tuning, spatial audio, ANC, and app support make them a well-rounded choice for users seeking an elevated everyday audio experience.
