AONIC 50 Gen 2
Wireless Headphones

General Description

Engineered from decades of stage and studio experience, the second generation of the AONIC 50 Wireless Noise Cancelling Headphones deliver premium, high- fidelity audio with improved active noise cancelling technology. New Spatialized Audio takes your listening experience outside of your headphones to a whole new level by replicating the experience of listening through high- end speakers. A modern “all-black” design and up to 45 hours of battery life keep the music going in comfort and  style, while customizable EQ and environment mode provide a personalized, unparalleled audio experience.
Features

• Premium, studio-quality sound through custom-engineered 50mm dynamic drivers. Developed from decades of professional experience made for critical listeners.
• Spatialized Audio technology uses a proprietary algorithm to enhance the depth of your listening experience by widening the sound stage without introducing unnatural artifacts. Available in three unique modes – Music, Cinema, or Podcast. Music mode replicates listening through high-end speakers in a room and maintains the original integrity of the track. Cinema mode enhances low-frequency response and clarity of speech for a movie theater experience. Podcast mode brings the voice of your favorite speakers close to your ears.
• New Hybrid Active Noise Cancelling (ANC) technology blocks out distractions for a truly immersive and natural listening experience improved over the prior generation. Using microphones inside and outside of the earcup, the second generation ANC allows you to control how much (or how little) of the outside world you hear. Featuring four selectable modes (Light, Moderate, Max and MaxAware), the new MaxAware setting allows you to block unwanted noise while still maintaining awareness of your surroundings – great for conversations on-the-go.
• Environment mode allows you to hear the outside world with the flip of a switch. Refine the ambience settings via an adjustable slider in the ShurePlus™ PLAY app.
• Up to 45 hours battery life with quick charge capabilities, more than doubling runtime from the prior generation. Fifteen minutes of charge provides 5 hours of use.
• Customizable EQ. Choose from multiple presets, or create your own using the free ShurePlus™ PLAY app. Saves directly to your headphones for a seamless audio experience across other apps and devices.
• Long-wearing comfort and durability in a patented design built to last. Folds flat in a new zippered carrying case designed for portability.
• Customizable fingertip controls provide quick access to answer calls, adjust volume, pause music or access default voice assistant with the push of a button. Assign your preferred features including Spatializer, EQ or ANC settings directly on the headphone for advanced control.
• Premium communication with clear call quality through beamforming microphone technology and proprietary automatic gain control (AGC) settings. Utilizing 6 microphones, the precision-engineered system automatically adjusts settings to avoid surrounding noise, offering unmatched quality for video and phone calls. Hear and be heard clearly.
• Bluetooth® 5 wireless technology with a class 1 transmitter delivers enhanced stability with a range of up to 100 meters (320 feet). Pairs to phones, tablets and laptops.
• Premium headphone amplifier and support for multiple codecs including Qualcomm® aptX™ , aptX™ HD, aptX™ Adaptive, AAC, SBC and Sony LDAC. Featuring Snapdragon Sound™ technology.
• High-Resolution USB Streaming up to 32-bit/384 kHz for an unmatched wired listening experience. Connect to wired sources with included 3.5mm analog audio cable or USB-C digital input for charging and High-Resolution streaming audio.
• ShurePlus™  PLAY app allows you to customize your preferences and control parametric EQ, noise cancellation, Spatializer and Environment Mode settings. Free to download for iOS and Android.

ShurePlus PLAY Mobile Listening App

General Description
The ShurePlus PLAY Mobile Listening App is a high-resolution music player with advanced EQ controls. Play uncompressed audio files with your iOS or Android mobile device using the music tab. Use built-in Shure EQ presets to customize the sound, or create your own EQ presets in the settings tab. Unlock environment mode and ANC features by connecting to Shure wireless and True Wireless products in the device tab.
Features

• Import and play multiple, high-resolution and standard file types
• Customize presets with the parametric graphic EQ
• Adjust your volume with the full-screen fader
• Create playlists and organize your music library by playlist, artist, album title, song title, genre, or composer
• Quickly dial in your sound with EQ preset modes for a variety of listening situations.

AONIC 50 and PLAY app sound processing
AONIC 50, Gen 2 headphones use all of your PLAY app DSP settings, regardless of how you are connected to the audio source and even after you have closed the app. The DSP occurs on the headphones and the app provides the access to customize those hardware settings.
Environment mode
Environment mode allows you to hear the ambient noise around you. This is especially useful when you want to listen to music or are on a phone call, yet you still want to be aware of the sounds around you.
To use environment mode, push the vertical switch on the back of the right earcup to the up position.
In the ShurePlus PLAY app, you can adjust the environment mode across eleven levels: Hear myself on calls
The Hear myself on calls setting allows you to hear your own voice on phone calls at a volume based on your Environment Mode setting. When switched off, the mics in the headphones still pick up your voice for phone calls, it’s just that you are not able to hear yourself.
Active noise cancellation
Active Noise Cancellation (ANC) allows you to suppress some or all of the noise around you. This is especially useful when traveling where road noise in a car, bus, or train, or jet noise in an airplane can force you to increase the volume.
To use ANC, push the vertical switch on the back of the right earcup to the down position.
In the ShurePlus PLAY app, you can adjust the ANC between four levels of noise cancellation:

• Light
• Moderate
• Max
• MaxAware

Spatializer
The Spatializer uses digital processing to make it sound like you’re in a larger setting using a pair of loudspeakers. The Spatializer options are:

• None – no change
• Music – the audio sounds like you’re in a recording studio
• Cinema – the audio sounds like you’re in a theater
• Podcast – the audio sounds like you’re in the room with the podcasters

The 4-band parametric equalizer is used to adjust the volume of independent, adjustable frequency ranges, to precisely shape the frequency response. The equalizer can be bypassed for a flat frequency response.

value is represented in octaves.

Commonly used EQ Adjustments
Treble boost for improved speech intelligibility: Add a high shelf filter to boost frequencies greater than 1 kHz by 3-6 dB
Ambient HVAC noise reduction: Add a low cut filter to attenuate frequencies below 200 Hz
Reduce flutter echoes and sibilance: Identify the specific frequency range that “excites” the sound:

1. Set a narrow Q value
2. Increase the gain to between +10 and +15 dB, and then experiment with frequencies between 1 kHz and 6 kHz to pinpoint the range of flutter echoes or sibilance
3. Reduce the gain at the identified frequency (start between -3 and -6 dB) to minimize the unwanted sound

Reduce hollow, resonant sound: Identify the specific frequency range that “excites” the sound and lower it:

1. Set a narrow Q value
2. Increase the gain to between +10 and +15 dB, and then experiment with frequencies between 300 Hz and 900 Hz to pinpoint the resonant frequency
3. Reduce the gain at the identified frequency (start between -3 and -6 dB) to minimize the unwanted sound

Preset Modes
Use presets to quickly access commonly used listening scenarios. Seven selectable 4-band presets optimize settings for gain, equalization, and compression. Play a song and find the preset that you think suits the song best, and then adjust levels as needed.
