However, the systems are costly compared to other models.
A wireless audio receiver and transmitter can perform multiple functions. If one device can receive and transmit signals, it can be used with speakers and other audio devices. The following features are key.
Bluetooth Version
The version is important because the latest versions, like Bluetooth 5.2, will have longer range and stability compared to older versions like 4.2. Transmitters with the latest version will work with devices that have older versions.
Compatibility
A wide range of compatibility to work with many audio devices is important. Ideally, the transmitter, receiver, and any device they connect to should all be compatible with each other. Transmitters and receivers should be compatible with at least three wireless audio transmission technologies: Bluetooth, Wi-Fi, and RF.
Low Latency
Audio latency or delay can cause sound and video to be out of sync, which is annoying. Look for low-latency transmission technologies like Bluetooth LEA and AAC to reduce latency.
High Definition (HD) Audio
Technologies like aptX HD, AAC, and LEA allow for lossless HD audio streaming. HD technologies can preserve the quality of lossless CDs or high-resolution audio files during wireless transmission.
Range
Devices with longer range allow for greater flexibility in setting up audio systems. The range depends on the transmission technology. Wi-Fi and RF devices usually have longer range than Bluetooth. Devices with the 2.4G RF band can transmit up to 100 feet.
Multi-Room Streaming
Wi-Fi and RF transmission allow users to stream audio to multiple devices or speakers simultaneously. Multi-room audio systems offer more convenience and features.
streaming Services
Wi-Fi Audio Transmitters allow users to connect to popular online streaming services like Spotify, Amazon Music, Pandora, Apple Music, and Deezer.
Device Control
New devices allow users to control the transmitter or receiver using their smartphone with transmitter apps or through a web interface.
Built-in DAC
A Digital-to-Analog Converter (DAC) can improve the audio output quality. It is useful if the device it connects to does not have a good DAC.
