## Description

desertcart.com: Syntech Airplane Bluetooth Transmitter Receiver 5.4 Adapter for 2 AirPods or Wireless Headphones, HD Display Low Latency 3.5mm AUX Jack Bluetooth Audio Adapter for Flying, TV, Car, Gym, Home Stereo : Electronics

Review: Bluetooth transmitters are great! Especially those from Syntech! - 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.
Review: Works Great in Both Modes - This adapter works well as both a transmitter and receiver. Pairing is quick, connection is stable, and the battery lasts a long time. Very useful for flights and other devices without built-in Bluetooth.

## Features

- 【2-in-1 Transmitter & Receiver: Break Free from Wires】Solve the hassle of tangled cables and incompatible devices—this 2-mode adapter works as both a transmitter and receiver for all scenarios. In transmitter mode, it wirelessly connects to in-flight entertainment systems, TVs, or gym equipment; in receiver mode, it streams audio from your phone/tablet to car stereos or home speakers effortlessly. The included dual 3.5mm AUX adapter ensures full compatibility with diverse aircraft audio interfaces, no extra accessories needed.
- 【HD Display & Dual Pairing: Share Audio with Ease】No more guessing connection status! The clear HD display lets you monitor pairing, battery level, and working mode at a glance, avoiding setup errors. Supports dual pairing to connect 2 AirPods or wireless headphones simultaneously—perfect for sharing in-flight movies with a partner, jamming to music with friends at the gym, or watching TV with family without disturbing others.
- 【Credit Card-Sized & Travel-Ready】Designed for on-the-go use: ultra-lightweight (lighter than a pack of gum) and only 1/3 the size of a credit card, it slips easily into your pocket, backpack, or carry-on. Comes with a dedicated storage pouch to keep the adapter, cables, and even earbuds organized—saves valuable space for your travel essentials, whether you’re flying cross-country or hitting the road.
- 【Stable Bluetooth 5.4 & Ultra-Low Latency】Powered by advanced Bluetooth 5.4 technology, it delivers lag-free audio with a minimum latency of only 180ms in SBC mode— the most widely compatible audio codec. Perfect for smooth movie watching on long flights (no lip-sync issues) or real-time music during intense workouts. With a 15-meter (49ft) connection range, you can move freely around the room, car, or gym without signal drops. Backward compatible with Bluetooth 5.3/5.2/5.0/4.2/4.0/3.0/2.0, it works seamlessly with all your wireless headphones, AirPods, speakers, and other devices. (Note: Packaging/user manual labels Bluetooth 5.3, but the actual chip supports Bluetooth 5.4 speed.)
- 【15-Hour Long Battery & Worry-Free Warranty】No need to panic about dead batteries during long trips: get up to 15 hours of continuous use on just a 1.5-hour fast charge—enough for 2+ cross-country flights or a full day of gym sessions. Backed by a 12-month warranty and responsive customer support, you can purchase with confidence, knowing any issues will be resolved quickly.

## Questions & Answers

**Q: What should I do if I can't connect the Bluetooth adapter to my Bluetooth headphones or speakers?**
A: First, ensure that the headphones or speakers are not connected to another device. Keep the devices close to each other (within 1 meter) during the pairing process. If connection problems persist, reset the Bluetooth adapter and headset/speaker.

**Q: No sound or only one side working when connected to headphones?**
A: 1. First, 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: 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.

**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: What should I do if there is a delay in use?**
A: 1. Stay within 10m of audio source; avoid walls/metal obstructions. 2. Prioritize devices with low-latency modes (e.g., LE Audio, aptX Low Latency). 3. Fewer Bluetooth devices nearby to prevent latency from channel congestion.

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Works Great in Both Modes

### ⭐⭐⭐⭐ Good quality, works well with minimal delay.
*by S***X on July 17, 2025*

This receiver worked extremely well and delivered excellent quality. There was a SLIGHT delay, but nothing overly noticeable that would last. It was very easy to set up and get connected. My only gripe is that I do not like how it just dangles, or how short the cord is. This leaves it hanging which can pull it out of the input, or leaves it susceptible to damage if someone is trying to squeeze by your seat, as the connector itself is fairly thin/low quality, evident by way too much wiggle and a feeling of bending when you move it with your fingers. Other than that, this is a solid adapter.
