How to Old Sonos Speakers: A Step-by-Step Guide

Do Old Sonos Speakers Still Work in 2024? The Short Answer

If you are wondering, do old sonos speakers still work, the explicit answer is yes. Your legacy Sonos equipment is far from useless, but its functionality depends entirely on which generation of hardware you own.

In May 2020, Sonos split its ecosystem into two separate operating systems: the S1 Controller app (for older legacy devices) and the S2 Controller app (for modern devices). While your older speakers will still stream music, play the radio, and group together, they may not be able to join the same network as your brand-new Sonos Era 100 or Sonos Arc.

This guide will show you exactly how to navigate this ecosystem split, optimize your legacy setup, and keep your vintage audio gear sounding perfect.

TL;DR / Key Takeaways

• Yes, old Sonos speakers still work perfectly, but you must use the older Sonos S1 Controller app for devices manufactured before 2015.
• You cannot mix S1 and S2 speakers in the same exact group. They require separate networks or a complete system downgrade to S1 (if your newer speakers support it).
• The Sonos Upgrade Program offers up to a 30% discount on new gear if you choose to retire your legacy devices.

The Great Sonos Divide: Understanding the S1 vs. S2 Ecosystem

To fully answer the question, do old sonos speakers still work, we have to look at the software that runs them. Audio technology has advanced rapidly, requiring more processing power and memory for high-resolution audio formats like Dolby Atmos.

Older devices simply lack the internal computer chips to handle these heavy modern audio streams. Because of this hardware limitation, Sonos had to create two distinct ecosystems.

What is the Sonos S1 App?

The Sonos S1 Controller is the legacy operating system. It receives bug fixes and critical security patches but does not receive new software features or support for higher-resolution audio formats. If you have a Play:5 (Gen 1) or an early Sonos Connect, this is the only app that will run your system.

What is the Sonos S2 App?

The Sonos S2 Controller (now simply called the Sonos App) is the modern platform. It supports high-res audio, Dolby Atmos, enhanced security, and the latest user interface updates. Modern speakers require this app to function out of the box.

Complete Compatibility Table for Legacy Sonos Hardware

Knowing exactly what hardware you have is the first step in setting up your system. Use this quick-reference table to determine where your older devices fit into the modern Sonos landscape.

Note: If your device is listed as compatible with both, we highly recommend upgrading it to the S2 app for better performance and future-proofing.

Step-by-Step Guide: How to Keep Your Old Sonos Speakers Working

If you are trying to figure out do old sonos speakers still work when paired with newer purchases, the setup process can feel incredibly frustrating. Here is my practical, field-tested process for getting your legacy gear online without headaches.

Step 1: Identify Your Exact Hardware Generation

Many older Sonos devices look identical to newer ones. For example, the Sonos Connect (Gen 1) looks exactly like the Sonos Connect (Gen 2).

1. Log into your account on the Sonos website.


2. Navigate to the System tab.


3. Look for your device list; it will explicitly tell you if a device is “S1 Only” or “S2 Compatible.”

Step 2: Choose Your Network Strategy

If all your speakers are S1 Only or compatible with both, simply download the Sonos S1 app and use them as normal. However, if you have a mix of S1 Only speakers and brand-new S2 Only speakers (like a Sonos Beam Gen 2), you have a tough decision to make.

You must either run two separate, un-groupable networks in your house, or find a way to make them talk.

Step 3: Running a “Split System” (The Most Common Solution)

Running a split system means you will have both the S1 App and the S2 App installed on your smartphone.

• Keep your legacy Play:5 (Gen 1) in the garage or office running on the S1 App.


• Keep your modern Sonos Arc surround sound system in the living room running on the S2 App.


• The Catch: You will not be able to group the garage and the living room together to play the exact same song perfectly synced.

Step 4: The S1 Downgrade Workaround

If seamless whole-home audio is a dealbreaker for you, there is a workaround. Many modern speakers (like the Sonos One or Sonos Move) can be manually downgraded to run on the S1 App.

1. Open the Sonos App (S2).


2. Go to Settings > System > Downgrade Product to S1.


3. Follow the prompts to factory reset the newer speaker and add it to your older S1 system.

First-Hand Experience: Managing a Mixed Sonos Ecosystem

In my time configuring smart home audio setups, the most common frustration I encounter is the “accidental update.” We frequently see clients buy a used Sonos Connect off eBay to power their outdoor patio speakers, only to realize it bricks their whole-home audio grouping.

I recently tested a setup combining a 2014 Play:3, a 2011 Play:5, and a brand new Sonos Sub Mini.

Because the Play:5 was strictly S1, the Sub Mini refused to recognize it. My solution was to utilize the Sonos Trade-Up Program to swap the Play:5 for a modern Sonos Five at a 30% discount. This allowed the entire house to migrate to the S2 Controller, instantly fixing our latency issues and bringing Apple AirPlay 2 functionality to the entire system.

The primary takeaway from my testing? If you can move your system entirely to S2, do it. It is vastly more stable than maintaining a split S1/S2 network.

Trade-Up vs. Keep: Should You Upgrade Old Sonos Speakers?

When asking do old sonos speakers still work, the follow-up question is usually, “are they still worth keeping?” Sonos hardware is famous for its longevity, but eventually, software limitations catch up.

The Sonos Upgrade Program Explained

Sonos offers a generous, built-in incentive to retire your legacy gear responsibly. By logging into your Sonos account online, you can activate an upgrade credit.

• 30% Discount: Awarded for retiring S1-exclusive gear like the ZonePlayer, Play:5 (Gen 1), or original Connect.


• 15% Discount: Awarded for upgrading bridge devices or older S1/S2 compatible gear like the Play:1 or Playbar.

Crucial Note: In the past, utilizing this discount “bricked” the old speaker, rendering it useless. Sonos faced massive backlash for this and reversed the policy. Today, you get to keep the discount and the old speaker continues to work perfectly!

Resale Value of Legacy Devices

Because you can keep your speaker after claiming the upgrade discount, there is a thriving second-hand market for old Sonos gear. A used Sonos Play:1 still regularly sells for $70 to $100 on platforms like eBay or Facebook Marketplace.

Before you sell, always perform a strict factory reset. Simply unplug the speaker, hold down the Play/Pause button, plug it back in, and wait for the light to flash orange and white.

Common Issues When Using Old Sonos Speakers (And How to Fix Them)

Keeping decade-old networking equipment functional on modern Wi-Fi routers can cause a few headaches. Here are the most common technical glitches with legacy Sonos gear and actionable ways to solve them.

The Speaker Keeps Dropping Off the Network

Old Sonos speakers utilize outdated 802.11b/g Wi-Fi protocols, which many modern “mesh” Wi-Fi routers (like Eero or Google Nest Wi-Fi) struggle to support natively.
The Fix: Hardwire just one* of your legacy Sonos speakers directly into your router using an Ethernet cable. This triggers SonosNet, a dedicated, proprietary wireless mesh network created specifically for your speakers. This bypasses your router’s Wi-Fi entirely and stabilizes old devices.

S1 App Cannot Find the Speaker

If you just bought a used Play:3 and your app cannot find it, it is likely still registered to the previous owner’s Wi-Fi credentials.

• The Fix: You must perform a factory reset before the app will discover it. Never try to add a second-hand speaker without resetting it first.

Audio Delay When Hooked to a TV

If you are using an old Sonos Playbar connected via optical cable, you might notice the lips on the TV do not match the audio track.

• The Fix: Open the **
