(Not compatible with phones, car stereos, or hearing aids.) 【Dual Headphones, One Source】Connect two Bluetooth headphones at the same time to share in-flight movies or music. Audio stays synchronized between both listeners, making it ideal for couples or family travel. 【NOT FOR Real-Time Or Instrument Use】NOT for musicians, gaming, live monitoring, karaoke, or electronic instruments. Bluetooth transmission introduces delay that makes real-time performance or rhythm-critical use unusable, even though audio quality itself is stable. 【LIMITED Bluetooth Behavior & Latency】Relay is a transmitter only and pairs only with headphones, not phones or tablets. Bluetooth must be turned off on previously paired devices to avoid auto-connection issues. Latency depends on headphones:aptX Adaptive ≈ low delay; Standard Bluetooth ≈ 150–200ms (lip-sync may be noticeable) Avantree Relay - Premium Airplane Bluetooth Adapter with Advanced Qualcomm Chipset, 2 Headphones Support, 25hrs Play Time, aptX Adaptive & HD Audio Transmitter for Airpods, Bose & Travel Flight
