SyncBuds
Listen together, perfectly synced, on your own earbuds 🎧
SyncBuds lets friends listen to the same audio in sync, each through their own earbuds. One phone hosts a room and others join over WiFi or hotspot. No backend, no accounts, and no internet required. Built with real-time clock sync, UDP audio streaming, jitter buffering, and drift correction. Open source.
Hey Product Hunt! 👋
I built SyncBuds because sharing one pair of earbuds is awkward, and playing audio separately on multiple phones never stays in sync.
🎧 One phone hosts
📱 Friends join from their phones
📶 Audio syncs over WiFi or hotspot
🚫 No backend, accounts, or internet required
The hardest part was keeping different phones synchronized despite network jitter and device latency. SyncBuds uses NTP-style clock sync, UDP audio streaming, jitter buffering, and drift correction.
It’s still early and open source. I’d love feedback, testers, and contributors! 🚀
