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
For travelers who want to use Bluetooth headphones with airplane seat 3.5mm audio jacks, without cables. Designed specifically for airplanes, seatback screens, and other 3.5mm audio-out sources – not phones or instruments.
Compatible with AirPods, Bose and all Bluetooth headphones. Simply plug the adapter into 3.5mm AUX jack to stream audio from airplane. (Not compatible with phones, car stereos, or hearing aids.)
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 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.
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)
