Share audio to multiple headphones simultaneously on Windows
No drivers. No complexity. Just click and listen.
You're on a train with your partner. You want to watch a movie together on your laptop. But Windows only plays audio through one device at a time.
Your options? Share one pair of earbuds (uncomfortable). Use a splitter cable (who carries those?). Let one person use the laptop speaker (everyone on the train hates you).
Double Headphones captures your system audio and routes it to two or more output devices at the same time. Bluetooth, wired, USB — any combination works.
- Connect both headphones
- Select them in the app
- Click Share Audio
- Both headphones play the same audio, in sync
That's it. When you stop sharing, everything goes back to normal automatically.
- Multi-device output — play audio on 2+ devices simultaneously
- No drivers required — pure Windows APIs, nothing to install
- Dead simple — three dropdowns and one button
- Any headphones — Bluetooth, wired, USB DACs, speakers, any mix
- Per-device volume — adjust each output independently
- Latency compensation — align Bluetooth with wired using a 0–2 second delay slider (type an exact value too)
- Crash-safe — if the app crashes, your audio restores automatically
- System tray — minimize and forget about it
- Lightweight — under 5% CPU
- Free forever — no ads, no telemetry, no tracking, no trial

Why do I hear audio from my laptop speakers?
You shouldn't. When one of your chosen outputs is also your Windows default device, the app quietly hands the default off to a spare output and mutes it, so nothing leaks out. If your machine has no spare device to hand it to, that one output plays normally and the app tells you — set a different device as your Windows default to silence it.
Netflix/Disney+ audio is silent
Streaming apps with DRM block audio capture. Use Chrome instead of the native Windows app — it works perfectly.
Audio is out of sync with video
Bluetooth adds 150-250ms of latency. Use the latency slider in the app, or adjust audio delay in your video player (VLC: press J/K).
Two Bluetooth headphones are stuttering
Two Bluetooth devices at once usually works fine — it's the whole point of the app. If you do hit stutters, moving the headphones closer to the PC helps most. On rare setups where a single built-in adapter can't keep up with two streams, a spare USB Bluetooth adapter (~$10) removes the bottleneck.
Can I use more than 2 devices?
Yes — the architecture supports unlimited devices. The current UI shows two, with more planned.
- DRM content (Netflix app, Edge) — use Chrome as workaround
- Bluetooth latency (150-250ms) — physics, use the latency slider
- Dual Bluetooth — works on most setups; a rare built-in adapter may stutter (move devices closer, or add a spare USB adapter)
- Windows 10 before build 20348 — required API not available
