Keep them within 1 meter during pairing. If problems persist, quickly press the pairing button 5 times in succession to reset the Bluetooth adapter and your headphones/speakers. **Q: What should I do if there is a delay in use?** A: 1. Stay within 49ft of audio source; avoid walls/metal obstructions. 2. Prioritize devices with Bluetooth 5.2 or above that support low-latency mode. 3. Fewer Bluetooth devices nearby to prevent latency from channel congestion. **Q: No sound or only one side working when connected to headphones?** A: 1. Check if the audio cable plug has dirt, debris, or liquid causing a poor connection—wipe clean if needed. 2. Ensure the audio plug is fully inserted into the output jack and the audio output is set to headphones. **Q: What to Pay Attention to in TX/RX Mode?** A: 1. The device does not support microphone functionality. 2. In TX mode, two devices can be connected simultaneously and used together. In RX mode, two devices can be connected, but only one can be used at a time. **Q: Can it be used for guitar or piano?** A: The Bluetooth transmission process can lead to inconsistent sound quality and delays. Therefore, it is not recommended for musical instrument performances, music events, or situations with stringent sound quality and latency needs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfectly to add Bluetooth to an old record player, the LCD makes it the superior choice! *by T***H on July 20, 2026* Using this (with an RCA to 3.5mm adapter) on an old record player to send music to my Yamaha soundbar, which is bluetooth capable.

Battery life lasted my entire international trip. ### ⭐⭐⭐⭐⭐ Bluetooth transmitters are great! Especially those from Syntech! *by T***D on March 2, 2026* This transmitter/receiver works great! I bought 2 of them. They are both for my niece who has cerebral palsy. One is for the TV and the other is for the stereo. That way she can have the sound as loud as she wants and she does not disturb anyone. They are both connected to her headphones. If she is watching the TV and wants to switch to the stereo, all she has to do is turn off the TV and then turn on the stereo. All this by just using her remotes. She loves it and we love it also. ## Frequently Bought Together - Syntech Airplane Bluetooth Transmitter Receiver for 2 AirPods or Wireless Headphones, HD Display Low Latency 3.5mm AUX Jack Bluetooth 5.3 Audio Adapter for TV, Flying, Car, Gym, Home Stereo - Syntech Airplane Bluetooth Transmitter Receiver for Airpods or Headphones, LED Display Dual Pairs Low Latency Wireless Bluetooth 5.3 Audio Adapter with Extra Dual 3.5mm AUX Adapter for Flight Car --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/691043886-airplane-bluetooth-transmitter-5-4-for-2-headphones-hd-display](https://www.desertcart.com.br/products/691043886-airplane-bluetooth-transmitter-5-4-for-2-headphones-hd-display) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-15*
