About This

• 【FOR In-Flight Wireless Listening】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.
• 【Stable Audio For Movies & TV】Uses a Qualcomm Bluetooth platform for reliable, interference-resistant audio during long flights. When paired with aptX Adaptive headphones, video and dialogue stay well aligned for movies and TV shows.
• 【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)
