Download and run the installer. No admin rights needed — it works right out of the box.
Toggle on the Bluetooth earbuds, speakers, or wired devices you want to broadcast to.
Press Start Broadcasting — your music, movies, or calls now play on every selected device in perfect sync.
Professional audio broadcasting without the professional complexity.
Whatever your laptop is playing goes to all your headphones and speakers together. Bluetooth or plugged in, it doesn’t matter.
Separate volume slider for each device. Give the speaker full blast while keeping earbuds at 30% — your call.
Devices slowly drift apart on their own — that’s why other setups start echoing after a while. SynchCast keeps correcting it, so a 3-hour film still lines up at the end.

Install in one click, connect your devices, and press play. That’s it.
Tuck it away next to the clock and forget it’s there. It keeps everything in sync while you watch.
Toggle devices on, adjust volume, hit broadcast. That's it.

SynchCast runs on Windows 10 and Windows 11. It only works on Windows — it relies on a part of Windows that macOS and Linux don't have, so there's no Mac or Linux version.
No. Nothing extra gets installed and you won't be asked for an admin password — just install it and open it. If you're weighing it up against VoiceMeeter, Virtual Audio Cable or Windows 11's Shared Audio, this comparison covers all four.
Up to about 5 at once. There's no limit built into the app, but most laptops start to struggle past five, so that's the honest number for playback without glitches. Most people use 2–3. SynchCast tells you roughly how many yours can handle.
No. Devices naturally drift apart over time — that's what makes other setups start echoing. SynchCast keeps correcting for it while you watch, so you can run a 3-hour movie and every device is still lined up at the end.
During the trial you get every feature unlocked with no limitations. After 30 days, you'll need to purchase a lifetime license ($10.99 one-time₹299 one-time) to continue using SynchCast. No subscription — pay once, own it forever.
The license is valid on 1 device at a time. To move to a new PC, open the app on the old one and click "Release this seat" — that frees up your licence — then enter the key on the new machine.
