If you've been searching for a way to boost your computer's audio, two names come up repeatedly: Boom 3D, the well-known desktop audio enhancement app, and Hearably, a browser-based audio extension for Chrome and Edge. Both promise louder, better sound — but they take fundamentally different approaches to the problem, and the right choice depends entirely on how you use your computer.
Boom 3D is a native desktop application available for macOS ($19.99 one-time) and Windows ($14.99/year subscription). It installs a virtual audio driver that intercepts your system's audio output, applying EQ, volume boost, and its signature 3D surround sound virtualization to everything — music apps, games, video players, video calls, system sounds. If you want every sound on your computer enhanced, Boom 3D's system-wide approach is powerful and well-executed.
Hearably takes a different path. It's a browser extension under 300KB that runs entirely inside Chrome or Edge. It uses Chrome's tabCapture API and Web Audio API to process audio on a per-tab basis — no drivers, no system modifications, no admin access required. You install it from the Chrome Web Store and it works immediately. The tradeoff: it only processes browser audio. Desktop apps like Spotify, VLC, or games are outside its scope.
For many users in 2026, this tradeoff makes Hearably the better choice. Consider how you actually consume audio: YouTube, Netflix, Spotify Web Player, Twitch, Zoom, Google Meet, podcasts in the browser, online courses. If 80% or more of your audio happens in the browser — and for most knowledge workers, remote employees, and students, it does — Hearably's per-tab control, zero-install simplicity, and free tier offer a more practical solution than a $20 desktop app.
But we want to be honest: if you need system-wide enhancement for desktop music players, games, or creative software, Boom 3D is better suited. If you value spatial audio virtualization for headphone listening, Boom 3D's 3D Surround feature is genuinely impressive and something Hearably doesn't attempt. This comparison breaks down every meaningful difference so you can make an informed decision based on your actual needs — not marketing claims.

System-Wide Driver vs. Browser-Level Processing
The fundamental architectural difference between Boom 3D and Hearably explains most of their respective strengths and limitations.
Boom 3D installs a virtual audio driver (kernel extension on macOS, virtual audio device on Windows) that sits between applications and your physical audio output. Every application's audio passes through this driver, where Boom applies EQ, volume boost, and spatial processing. This gives Boom 3D system-wide control but comes with costs: driver installation requires admin privileges, virtual drivers can conflict with other audio software (DAWs, virtual meeting apps), and macOS Ventura and later require explicit kernel extension approval. The driver approach also means Boom processes a single mixed audio stream — it cannot treat individual applications differently.
Hearably operates entirely in the browser's Web Audio API context. When you enable it on a tab, Chrome's tabCapture API captures that tab's audio stream and routes it through Hearably's DSP chain: a 10-band parametric EQ, 3-band Linkwitz-Riley crossover feeding per-band compressors, per-band gain stages, and a look-ahead limiter AudioWorklet. Each tab gets its own independent processing chain with its own settings. This browser-level approach means zero driver installation, zero system risk, and cross-platform compatibility (Windows, macOS, Linux, ChromeOS) — but it only processes audio inside Chrome or Edge.
On audio quality: Boom 3D's processing adds approximately 15-25ms of latency due to the driver pipeline. Hearably's Web Audio processing adds under 10ms (5ms from the look-ahead buffer plus Web Audio scheduling overhead). Both are imperceptible for media consumption, but Hearably's lower latency is noticeable in video calls where lip sync matters.
How to get the best audio on Hearably vs Boom 3D
Choose Hearably if most of your audio is in the browser
If you primarily use YouTube, Netflix, Spotify Web, Twitch, Zoom, and Google Meet, Hearably gives you per-tab control that Boom 3D cannot match. You can boost a quiet tutorial to 400% while keeping a background music tab at 80% — each with its own EQ preset.
Choose Boom 3D if you use desktop audio apps
If you regularly use desktop Spotify, Apple Music, VLC, or PC games, Boom 3D's system-wide audio driver will enhance all of them. Hearably only processes audio inside Chrome and Edge — it cannot touch desktop applications.
Choose Hearably if you want zero installation risk
Hearably is a browser extension under 300KB — no kernel drivers, no admin access, no system modifications. Boom 3D requires a virtual audio driver that can occasionally conflict with DAWs, virtual audio cables, or conferencing software. If your work depends on audio stability, Hearably is the safer choice.
Choose Boom 3D if spatial audio matters to you
Boom 3D's 3D Surround virtualization is genuinely impressive for headphone listening — it creates a convincing sense of speaker-like width and depth. Hearably focuses on volume, EQ, and dynamics processing but does not attempt spatial audio simulation.
Choose Hearably for cross-platform consistency
Hearably works identically on Windows, macOS, Linux, and ChromeOS — anywhere Chrome or Edge runs. Boom 3D has separate apps for macOS and Windows with different pricing models, and doesn't support Linux or ChromeOS at all.
Consider using both together
Boom 3D handles system-wide audio (desktop apps, games), while Hearably handles browser audio with per-tab precision. They operate at different levels of the audio stack and don't conflict. This gives you the best of both worlds if you need comprehensive enhancement.
Choose Hearably if you want a free option
Hearably offers a free tier with up to 120% boost and 3-band EQ — enough for many users. Boom 3D has no free tier; it's $19.99 upfront on macOS or $14.99/year on Windows. Hearably Pro (800% boost, 10-band EQ, all presets) is $4.99/month or $49.99/year.
Built for this exact use case
Per-Tab Audio Control
Hearably gives each browser tab its own independent audio chain with separate volume, EQ, and presets. Watch a Netflix movie at 300% with Cinema mode while a background YouTube tab plays at 80% with Bass Boost. Boom 3D processes all audio as a single mixed stream.
Zero-Distortion Look-Ahead Limiter
Hearably's custom AudioWorklet limiter analyzes peaks 5ms before output and smoothly reduces gain to prevent clipping. At 800% boost, audio stays clean. Boom 3D uses traditional limiting that can introduce audible pumping at high volumes.
No Driver Installation
Install from Chrome Web Store in 3 seconds. No admin password, no kernel extensions, no virtual audio devices, no reboot. Works on locked-down corporate laptops, school Chromebooks, and shared computers where Boom 3D cannot be installed.
10-Band Parametric EQ
Precise frequency shaping from 31Hz to 16kHz with ±12dB per band. Boom 3D offers a simpler EQ with fewer bands. Hearably's EQ runs per-tab, so you can shape each audio source independently.

Frequently asked questions
Can I use Hearably and Boom 3D at the same time?
Yes. They operate at different levels — Hearably processes audio inside the browser's Web Audio context, while Boom 3D processes audio at the system driver level. They don't conflict. Browser audio would pass through Hearably first, then through Boom 3D's driver.
Does Boom 3D have per-app volume control?
No. Boom 3D processes a single mixed audio stream at the driver level. It cannot apply different settings to different applications. Hearably provides per-tab control within the browser — each tab has independent volume, EQ, and preset settings.
Which has better audio quality at high volumes?
Hearably. Its look-ahead limiter prevents distortion at any volume level by anticipating peaks 5ms before they occur. Boom 3D uses traditional processing that can introduce artifacts at extreme volume levels.
Does Boom 3D work on ChromeOS?
No. Boom 3D requires macOS or Windows and installs a system-level audio driver. Hearably works on any platform that runs Chrome or Edge, including ChromeOS, Linux, macOS, and Windows.
Which is cheaper?
Hearably has a free tier (120% boost, 3-band EQ). Boom 3D has no free option — it costs $19.99 on macOS (one-time) or $14.99/year on Windows. Hearably Pro costs $4.99/month or $49.99/year for 800% boost, 10-band EQ, and all presets.
Does Boom 3D work with Netflix and YouTube?
Yes, but only system-wide. Boom 3D boosts all audio equally — it can't give Netflix a Cinema preset while keeping YouTube flat. Hearably applies independent processing per tab.
Which is better for video calls?
Hearably. Its per-tab control lets you boost a quiet Zoom call to 300% without affecting other tabs. The sub-10ms latency keeps lip sync accurate. Boom 3D's system-wide processing and higher latency (15-25ms) make it less ideal for real-time communication.
Can Boom 3D boost volume above 100%?
Yes, Boom 3D can amplify system audio above the OS volume limit. Hearably can boost to 800% (8x). Both achieve significant volume increases, but Hearably's look-ahead limiter ensures distortion-free output at extreme levels.
