What is second screen behavior?

Second screen behavior is when viewers use a phone or tablet while watching TV or streaming. For Gen Z and Millennials, it’s now a natural extension of the viewing experience.

How common is second screen use among Gen Z and Millennials?

Very common. 85–89% of Gen Z use a mobile device while watching TV, and over 76% of Gen Z and Millennials say they often or always browse the internet on a second device. Smartphones are the dominant second screen, with ownership near universal.

What do people do on their second screens while watching?

Typical activities include checking social media and messages, looking up show-related info, and shopping links tied to what’s on screen.

Why does second screen behavior matter for streaming platforms?

It’s the norm, not the exception. Managed well, it drives deeper engagement, longer watch time, stronger retention, and new monetization opportunities.

How does Sound Dimension’s AiFi use the second screen?

AiFi turns phones into synchronized speakers, integrating them into the sound experience for social listening, surround sound across devices, and immersive group sessions.

How does AiFi improve engagement instead of causing distraction?

By keeping the phone inside the experience: the second screen becomes a sound extension of the story, reinforcing immersion rather than pulling viewers into competing apps.

Can second screen behavior help content go viral?

Yes. Second screens are where conversations happen. Shared listening and synchronized group moments are inherently social, boosting organic sharing and recommendations.

What monetization opportunities does AiFi unlock?

Premium synchronized live events, upsells for group sound experiences, sponsorships and branded events, plus audience intelligence on participation and session behavior.

How does AiFi help reduce churn?

AiFi makes the phone an extension of the platform, not an exit point. Synchronized sound across devices increases watch time, strengthens social bonds, and lowers churn.

Turn Phones Into a Mesh Sound System for Shared Audio

From Solo Listening to Shared Streaming

Most of us walk around with a powerful speaker in our pocket, but we usually use it for a very small thing. One phone, one listener, tiny sound. When friends get together to share a song or a video, everyone leans over one device, or someone fights with Bluetooth and a single speaker. The moment is shared, but the sound is not.

We asked a simple question: What if you could turn phones into a mesh sound system for instant shared streaming? Instead of one lonely phone on a table, every phone in the room could join in, filling the space with sound. In this article, we will talk about what that means, how it works, and why it can change the way people listen together.

What Is a Mesh Sound System?

A mesh sound system is what you get when you turn phones into a mesh sound system that cooperate instead of compete. It is a group of devices in the same space, like phones, tablets, or other speakers, that all play the same audio at the same time as one team. No one device is the boss; the sound flows across all of them together.

That is very different from a basic Bluetooth setup. With a normal Bluetooth speaker, one device sends the sound, and one speaker plays it. If you want more sound, you have to add more hardware, pair new devices, and hope they stay in sync.

With a mesh sound system, nearby devices can:

Join or leave the group without stopping the sound
Spread the audio around the whole room instead of in one direction
Give each listener their own speaker near them
Make shared moments feel more balanced and fair for everyone

The result is louder, wider, more immersive sound that feels like it comes from the whole room, not just from a single point.

How AI Audio Synchronization Makes It Work

Making this work is not as simple as pressing play on every phone at once. Each device has its own hardware, its own operating system, and its own delays. Networks are messy. If you try to sync sound by hand, you end up with tiny echoes and strange timing that make music and speech feel wrong.

This is where AI audio synchronization comes in. At Sound Dimension, we work with AI that listens to timing, latency, and room acoustics, then constantly adjusts each device so they stay in step. The AI reacts as conditions change, like someone moving their phone or joining the group late.

With AiFi, our software-only SDK, developers can reliably turn phones into a mesh sound system that sounds like a single smart speaker. Because AiFi is software-only, there is no need for special hardware or custom speakers. Apps and platforms can tap into the microphones and speakers people already carry and let AI line everything up in real time.

Real-World Use Cases for Shared Streaming

Once you turn phones into a mesh sound system, new shared streaming experiences become possible. Everyday hangouts and events can suddenly sound much richer, without anyone buying new gear or rewiring a room.

Here are a few simple examples:

Social listening: Friends in the same room hit a button in an app, and their phones link together. The group can play a playlist, and the music fills the room from every side, not just from one corner.
Video and watch parties: When people watch a movie or clip on a TV or laptop, their phones can join in, boosting the soundtrack. Dialog stays clear, and sound effects feel bigger without blasting a single soundbar.
Commerce and experiences: Retail spaces, events, and venues can invite visitors to join a shared audio experience with their own phones, like guided tours, mood soundscapes, or special promotions.

Because the system is software-based, these experiences can adapt easily to different spaces, from small apartments to larger public areas. In our home base in Sweden, where winter evenings can be long and indoor time is important, this kind of shared sound can make living rooms, dorms, and offices feel more alive.

Why Platforms Should Care About Shared Audio

For app makers and streaming platforms, audio is not just about volume, it is about connection. People want to share what they love, and they already pass phones around or shout for others to listen. A built-in shared mode makes that feel natural instead of clumsy.

By choosing to turn phones into a mesh sound system, platforms can:

Offer a unique shared streaming feature that goes beyond headphones
Encourage people to stay longer in sessions because they are listening together
Support group experiences without asking users to buy special speakers
Keep control inside the app, instead of sending the experience off to external devices

Because AiFi is software-only, platforms can turn phones into a mesh sound system without manufacturing hardware or changing user behavior drastically. Users just open an app they already know, tap to join, and their phone becomes part of the sound field. The shared feature becomes another reason to play one more song or watch one more episode with friends.

How Developers Can Integrate AiFi

From a developer’s point of view, all the complex audio logic sits inside the AiFi SDK. You focus on the user experience, while AiFi handles discovery, synchronization, and spatial effects in the background.

The basic flow looks like this:

Detect nearby devices running the same app and willing to join
Establish a local mesh between those devices
Sync playback and keep timing tight across the group
Adjust for different speakers, positions, and room acoustics

With AiFi, we provide tools for iOS, Android, and other platforms so the shared audio logic fits into existing technical stacks. With a few lines of code, you can turn phones into a mesh sound system directly inside your existing app experience. You keep control over the design, buttons, and flows. AiFi quietly runs the timing and sound shaping behind the scenes.

The Future of Shared Audio Experiences

We see a future where shared streaming is normal, not special. Dorm rooms, offices, hotel rooms, and family spaces can quickly turn into shared listening zones whenever people are together. Phones are already there, pockets are already full, and AI can make them feel like one smart, flexible sound system.

At Sound Dimension, we focus on software-defined audio that lowers the barrier to spacious, room-filling sound. As more platforms turn phones into a mesh sound system, shared streaming will feel as natural as pressing play.
