• Touch Controls: Some Bluetooth audio adapters have touch controls to adjust the volume, skip tracks, answer calls, and power on and off. They are easy to use and respond quickly to light taps.
• Noise Cancellation: Some audio adapters have active noise cancellation technology that reduces environmental sounds. This enables users to have clear conversations and listen to music even in crowded and noisy places.
• Multipoint Connectivity: This feature enables Bluetooth audio adapters to connect to two or more Bluetooth devices simultaneously. For instance, one can connect the audio adapter to a Bluetooth transmitter and smartphone or two music players at the same time. Incoming calls or audio signals will interrupt the streaming playing so the user can respond or continue listening. This feature improves versatility and convenience since users don't have to disconnect and connect the transmitter repeatedly.
• Built-In Microphone: A built-in microphone allows users to make hands-free calls. The microphone picks the user's voice and transmits it to the other person, ensuring the conversation is clear and understandable.
• Smart Voice Assistant: Some Bluetooth adapters support smart voice assistants like Alexa, Siri, and Google Assistant. Users can command the voice assistant to do various tasks like making calls, playing music, and sending messages.
• Easy Pairing and Configuration: Bluetooth adapters with easy pairing and configuration features have simplified setup processes. They use NFC, voice prompts, LED indicators, or touch controls. These features make the adapter accessible to people with little technical knowledge.

How to choose a Bluetooth audio adapter

When choosing a Bluetooth audio adapter, there are several factors one should consider to find an adapter that better suits their needs.

• Audio Quality

  The audio quality should be good and the adapter should support efficient codecs to provide a better sound. Look for an adapter that supports AptX, as it improves the quality of the streaming audio. These codecs help reduce the amount of compressed sound that is sent over Bluetooth.

• Compatibility

  Make sure the adapter is compatible with the audio device intended to be used, whether it is a smartphone, tablet, laptop, or PC. Also, check the compatibility with the audio device the adapter is going to be connected to, whether it is a pair of Bluetooth headphones, speakers, or any other audio gear.

• Connectivity Options

  The best Bluetooth audio adapter should include multiple connectivity options. Although Bluetooth is becoming a standard in audio transmission, some adapters still have a wired connection option using a 3.5mm audio jack with a cable to connect to a speaker. Some adapters come with a toslink optical cable that aids transmitting digital audio to a speaker or soundbar.

  Also, look for an audio adapter that features a 3.5 mm audio jack or RCA so it can connect to stereos and other devices without Bluetooth connectivity.

• Battery Life

  Check how long the Bluetooth adapter battery lasts on a single charge. The adapter should at least last for 8 hours on a single charge without needing to recharge. Also, consider how long it takes to recharge the adapter after the battery runs out.

• Range

  Consider the range of the Bluetooth adapter and make sure it is suitable for the intended use. Most Bluetooth adapters offer a range of 30 feet. However, some adapters can go as far as 120 feet. These long-range adapters give users greater flexibility, as they can easily move around without losing the connection.

• Particular Needs

  Consider any additional features that meet specific audio needs. For low-latency streaming, look for an adapter that supports AptX Low-Latency. These encoders offer less than 40 milliseconds latency, which is perfect for streaming-sensitive content like gaming and video.

  If using a Bluetooth audio adapter with a built-in microphone, look for an adapter with multi-function buttons that allow to answer or end calls.
