How to Switch Modes on Dual-Form ANC Open Earbuds: Aerofit 2 Pro User Guide

The soundcore Aerofit 2 Pro represents a significant evolution in personal audio, offering a unique dual-form design that bridges the gap between situational awareness and immersive focus. Unlike traditional earbuds that lock you into a single listening experience, the Aerofit 2 Pro provides two distinct physical forms: an Open-Ear Form for staying connected to your surroundings and an ANC Form for deep, distraction-free listening. This guide will walk you through every method of switching between these modes, from the intuitive physical interaction to the smart automatic detection and the granular control offered by the soundcore APP. Mastering these techniques allows you to tailor your audio experience perfectly for any scenario, whether you're running outdoors, commuting on a noisy train, or needing to concentrate in a busy office.

Understanding Dual-Form ANC Open-Ear Earbuds: Open-Ear vs. ANC Mode

Before diving into the switching mechanisms, it's crucial to understand what each form offers. This foundational knowledge explains why you would switch modes and sets the stage for mastering the how.

The Open-Ear Form is characterized by its non-invasive design, a defining feature of modern Open Ear Earbuds. The speaker driver rests just outside the ear canal, delivering sound without creating a seal. This form is engineered for environmental awareness, allowing you to hear traffic, conversations, and ambient sounds clearly. It is an ideal choice for outdoor activities like running or cycling, working in environments where you need to remain approachable, or any situation where safety and spatial awareness are priorities. Comfort is a key advantage, as the open design eliminates direct ear canal contact, helping avoid the stuffiness and itchiness commonly associated with traditional in-ear models.

The ANC Form is activated by gently rotating the adjustable ear hook, transforming the earbuds into ANC Open Earbuds by positioning the speaker tip into a shallow, sealed fit. This configuration enables Adaptive ANC (Active Noise Cancellation), which uses microphones to analyze and counteract external noise in real time. It effectively reduces ambient sounds in busy settings such as subways, airports, or open-plan offices, ensuring that music, podcasts, or calls remain clear and intelligible. This mode also minimizes sound leakage, supporting greater listening privacy without disturbing those nearby.

Method 1: How to Manually Switch Between Open-Ear and ANC Modes

The most immediate and tactile way to change modes is through the physical design of the earbuds themselves. This method leverages the innovative Adjustable Ear Hook 2.0.

Step-by-Step Process:

1. Locate the Ear Hook Joint:Identify the flexible hinge where the speaker housing connects to the ear hook.
2. For Open-Ear Mode:Ensure the speaker housing is positioned away from your ear canal, not creating a seal. The ear hook should be resting comfortably over the top of your ear.
3. For ANC Mode:Gently rotate the speaker housing forward and inward by approximately 56 degrees. You will feel it settle into a shallow, secure fit within the concha of your ear, creating the necessary seal for noise cancellation. The 5-gear adjustable ear hook ensures this movement is precise and the fit is secure for all ear sizes.
4. Confirmation:A subtle voice prompt will announce "Noise Canceling On" when you successfully switch to ANC mode and "Noise Canceling Off" when you return to Open-Ear mode.

This manual open/ANC switch is perfect for intentional, scenario-based changes. Heading into a loud coffee shop? Rotate to ANC. Stepping out for a walk where you need to hear traffic? Rotate back to Open-Ear. It’s that simple.

Method 2: Automatic Mode Detection via the Sensor on Dual-Form ANC Open-Ear Earbuds

Beyond manual control, the Aerofit 2 Pro features intelligent automation designed to streamline your experience. This is powered by a built-in mode detection sensor.

How It Works:
The earbuds are equipped with a sensor that detects their physical orientation and fit relative to your ear. When you manually switch forms using the ear hook, this sensor recognizes the change and triggers two key automated responses:

1. Mode Toggle:It automatically activates or deactivates the Adaptive ANC circuitry.
2. Adaptive EQ Adjustment:The system intelligently applies a tailored sound profile optimized for the specific form. In Open-Ear Form, the EQ boosts clarity and compensates for the lack of a seal. In ANC Form, it optimizes for bass response and immersive sound within the sealed environment. This audio adjustment happens seamlessly in the background, ensuring optimal sound quality regardless of how you wear them.

You don't need to fiddle with an app or remember settings. The earbuds intelligently match the audio output to your chosen wearing style. This smart integration of hardware and software ensures you always get the best possible sound for the mode you're in.

Method 3: Switching Modes Using the soundcore APP

For users who desire ultimate control and customization, the soundcore APP (available for iOS and Android) is your command center. This is where you can manage settings that the automatic systems handle, or create your own personalized profiles.

Key Features for Mode Management:

• Direct Mode Selection:Within the app's main control interface, you can manually select between "Noise Canceling" (ANC Form profile), "Transparency" (enhanced Open-Ear awareness), and "Normal" modes. This is useful if you want to force a specific audio processing mode regardless of the physical form.
• Adaptive EQ Customization:While the Adaptive EQ works automatically, the app gives you access to a full graphic equalizer. You can create and save custom EQ presets for different genres of music or specific activities, and these presets will be applied based on your mode selection.
• ANC Intensity Adjustment:In the ANC mode settings, you can potentially adjust the strength of the noise cancellation to suit your preference, from fully immersive to a lighter cancelation that lets some ambient sound through.
• Button Customization:You can reassign the functions of the physical touch controls on the earbuds. For instance, you could set a long-press on the left earbud to cycle through listening modes directly, adding another layer of switching convenience.

Learning how to use dual-form ANC open earbuds fully means becoming proficient with the soundcore APP. It unlocks a deeper level of personalization, allowing you to refine the automated experience to your exact liking.

Best Use Scenarios for Dual-Form ANC Open-Ear Earbuds

Knowing how to switch modes is most powerful when applied to daily life. Here are practical applications:

• Running & Outdoor Fitness:Start in Open-Ear Form. Enjoy your playlist while maintaining critical awareness of traffic, cyclists, and other people. The secure, comfortable fit from the adjustable ear hook prevents slippage during vigorous movement.
• Commuting (Bus/Train/Subway):Use the manual open/ANC switch as you board. Rotate to ANC Form to engage Adaptive ANC, dramatically reducing engine rumble and crowd noise for clear audio or peaceful silence.
• Office & Study Sessions:In an open office, use ANC Form to minimize distracting conversations. If a colleague needs your attention, a quick manual switch to Open-Ear allows for conversation without removing the earbuds. The mode detection sensor and Adaptive EQ will handle the audio transition seamlessly.
• Cycling:Always use Open-Ear Form for maximum safety. The open design ensures you can hear horns, sirens, and other vehicles clearly while still enjoying motivational audio.

Troubleshooting Mode Switching Issues on ANC Open-Ear Earbuds

• ANC Not Activating:Ensure the earbud is rotated fully into your ear to create a seal. The mode detection sensor requires this proper fit. Check the app to confirm ANC mode is not manually disabled.
• Voice Prompts Not Playing:Verify the voice prompt volume is turned on in the soundcore APP
• Sound Quality Seems Off in One Mode:Use the soundcore APP to check the EQ setting. Try resetting to the default Adaptive EQ profile. Ensure the earbud is clean, as a blocked grill can affect sound, particularly in the sealed ANC Form.
• Earbud Not Staying in ANC Position:Utilize the 5-gear adjustable ear hook to find a tighter, more secure fit. The 56-degree rotation should feel firm and locked in.

Frequently Asked Questions (FAQs)

Can I use ANC mode without switching to the sealed ANC form?

No, for optimal performance, the Adaptive ANC is designed to work in conjunction with the physical seal created by rotating the earbud into the ANC Form. The mode detection sensor typically enables ANC processing when it detects this sealed position. Using ANC without the proper seal will result in significantly reduced noise cancellation effectiveness and subpar audio quality.

Does automatic mode detection work inside the charging case?

No, the mode detection sensor and the earbuds' processing systems are active only when the earbuds are powered on and out of the case. Mode changes should be made while wearing the earbuds or while they are on and connected to your device.

Will the earbuds remember my custom EQ setting from the soundcore APP when I switch between modes?

Yes, custom EQ settings saved in the soundcore APP are stored on the earbuds themselves. When you manually select a listening mode (like Noise Canceling or Normal) via the app, your associated custom EQ for that mode will be applied. The automatic Adaptive EQ that triggers with the physical form switch uses soundcore's optimized default profiles, but you can override this with your preferred custom EQ for each mode within the app's settings.

How do I update the firmware on my Aerofit 2 Pro, and will it improve mode switching?

Firmware updates are managed through the soundcore APP. When an update is available, you will typically receive a notification within the app. It is recommended to keep your earbuds updated, as firmware releases can include improvements to the reliability of the mode detection sensor, enhancements to ANC performance, and refinements to the automatic audio adjustment algorithms.
