Our first app

Every room, one screen.

KlingKlang is a controller for the Sonos speakers you already own. It is quick, it asks for nothing, and it speaks to your speakers directly over your own home network.

Affordable. No account. No adverts.

KlingKlang is made by us, not by Sonos. We are not connected with Sonos, Inc. in any way, and they have not approved or sponsored this app. We mention their name only so you know which speakers KlingKlang works with.

Why we made it

Because the old app was slowing your Mac down

Sonos' own desktop app was written for the Intel processors Apple stopped using years ago. On a modern Mac it has to be translated as it runs, which makes it slow to open and heavy on the battery. Apple will not keep that translation forever.

Sonos have not replaced it with a new Mac app. What they offer instead is a website, play.sonos.com, which you open in a browser and sign in to with a Sonos account. Your commands travel out to Sonos' servers and back again, so if your internet is down, you cannot turn your speakers up — even though they are sitting in the next room, on your own network.

KlingKlang was written from scratch for today’s Macs, and then for phones and tablets too. It opens immediately, it talks to your speakers directly over your own network, and it will keep working.

Put rooms together, or take them apart

Tap a room to see which others are playing with it, then add or remove them as you like. Send one song to the whole home, or give the kitchen something of its own. There is a button for grouping everything at once, and one for undoing it.

Turn one speaker down without touching the rest

Touch the volume of a group and every speaker inside it appears, each with its own slider. Turn the television speaker down while the rest of the room carries on. Move the group slider instead and they all follow together, keeping the balance you set.

Keep your speakers up to date

KlingKlang tells you what each speaker is running and installs the update Sonos is offering, without making you open another app. Older speakers that Sonos keeps on their own release are marked as such and left alone, rather than being offered something that was never meant for them.

Everything else it does

The small things you use every day

Your own music

Point KlingKlang at the folder of music on your network drive and browse it by artist, album, genre or composer — even if there are tens of thousands of tracks.

The services you already have

Search and play from the streaming services set up on your system, such as Spotify, TuneIn, SoundCloud and Pocket Casts, plus your favourites and playlists.

Alarms and a sleep timer

Wake up to a room of your choosing, and let the music fade out after you have fallen asleep.

A record player, anywhere

If something is plugged into the back of a speaker, any room can listen to it. Put the turntable in the living room and hear it in the kitchen.

A smaller window

On the Mac, swap the full window for a small player that stays in a corner, and control the music from the menu bar without switching apps.

The buttons you already press

The volume keys on your Mac keyboard and the volume buttons on your phone control the room you are looking at.

Knows your speakers

Each room shows the shape of the speaker actually standing in it, and portable speakers show how much battery they have left.

Five languages

English, German, French, Italian and Spanish, chosen automatically from your device’s own language setting.

Get KlingKlang

Affordable, on the devices you own

KlingKlang is coming to the App Store and to Google Play. Getting it there is the only way we will offer it: the stores check every app before it is published, keep it updated for you, and let you remove it as easily as anything else.

It will carry a modest price, and the store you buy it from takes care of the payment and the updates. We will put the links here the day each version is approved, and this is where to look for them — we do not hand the app out anywhere else.

What you need

  • A Mac with Apple silicon (M1 and newer) on macOS 14 or later, an iPhone or iPad on iOS 18 or later, or an Android phone on Android 10 or later
  • Sonos speakers connected to the same home network as your device
  • For your own music: a shared folder on a network drive or computer at home
Before you ask

Questions people usually have

Does it replace the Sonos app?

For day-to-day listening, yes. You will still need the Sonos app once, to set a brand new speaker up on your network, and for a few settings that only Sonos can change. After that KlingKlang can do the rest.

Do I need a Sonos account to use it?

No. KlingKlang never asks you to sign in. It finds your speakers on your own network and talks to them directly.

Will it work with my speakers?

If your speakers work with the Sonos app on the same network, they will work with KlingKlang. It handles older and newer models side by side, including stereo pairs and portable speakers.

Why does my Mac ask about the local network?

The first time you open KlingKlang, macOS asks whether it may talk to devices on your home network. That is how it finds your speakers. Say yes, or the app will not see anything.

What does it cost?

KlingKlang is a paid app, priced to be easy to say yes to. You buy it once from the store, with nothing to subscribe to and nothing to unlock later. There are no adverts, and nothing about you is sold.

What does it send about me?

Nothing. There are no accounts, no adverts and no analytics of any kind. Updates arrive through the store you installed it from, like every other app on your device.

Privacy

It stays in your house

KlingKlang speaks to the speakers on your own network and to nothing else. There is no account, no advertising and no analytics — not a reduced amount, none at all. When you browse a streaming service, the app asks that service directly, exactly as the Sonos app does, and your login for it stays in your device’s own secure storage.
