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! π
I built SyncBuds because sharing one pair of earbuds is awkward, and playing audio separately on multiple phones never stays in sync.
π§ One phone hosts
π± Friends join from their phones
πΆ Audio syncs over WiFi or hotspot
π« 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.
Itβs still early and open source. Iβd love feedback, testers, and contributors! π
