Pairing Two Bluetooth Headphones to a Single Phone: Understanding the Limitations and Future Prospects

Introduction to Bluetooth Headphone Pairing

No, most modern mobile phones, running on either Android or iOS software, do not support simultaneous Bluetooth connections for both call and music purposes. Instead, you can either pair one device and use an application for another, or alternate between them. Bluetooth is primarily designed for transmitting audio and small files between devices, but it has limitations in terms of handling multiple simultaneous connections.

Understanding Bluetooth Connections on Smartphones

Modern smartphones allow you to connect a primary Bluetooth device, such as headphones, and an additional device that can be used for file transfer or other non-audio tasks. For instance, you can seamlessly switch between headphones and a smartwatch for calls. This creates the misconception that you can simultaneously play audio on two sets of headphones connected via Bluetooth.

Connecting Multiple Devices

To connect multiple devices, you must disconnect the primary one to connect the secondary device. For example, if you have a Bluetooth headphone and a smartwatch, you can connect your headphones and use the smartwatch for other applications, or vice versa. When a call comes in, you can switch between devices using the phone's built-in functionality.

Bluetooth 6 and LE Audio

The long-term solution for simultaneous Bluetooth connections is the upcoming Bluetooth 6, also known as LE Audio. This standard has been in development since May 2020, and while it promises significant improvements, its implementation is delayed due to the global impact of the COVID-19 pandemic. LE Audio is expected to be available by the end of 2022, with further availability in the early months of 2023.

Expected Features of LE Audio

Once LE Audio is available, users will be able to pair multiple headphones to a single BT transmitter. This will be especially beneficial for true wireless earbuds (TWS) where audio can be sent to separate channels to left and right earbuds. This improvement reduces the sync burden and enhances audio fidelity. Additionally, LE Audio will include functionalities such as Auracast, which will enable applications like hearing aids and public address systems. In Auracast-enabled environments, users can select specific audio streams, such as announcements or live events, tailored only to their needs.

Current Limitations of Bluetooth Headphones and Earbuds

As of now, Bluetooth 4.xx and 5.xx headphones and TWS earbuds cannot be used for LE Audio and Auracast. They will need to be replaced with newer models to take advantage of these new features. Future-proofing your audio equipment is important if you want to enjoy the latest advancements in wireless audio technology.

Conclusion

While simultaneous Bluetooth connections for call and music are not yet available, the advent of LE Audio and Auracast promises a significant improvement in the way we use Bluetooth headphones and earbuds. By the end of 2023, users should be able to enjoy better audio quality and more versatile usage with new LE Audio-enabled devices. Keeping up with technological advancements in this space is crucial for enjoying the best possible audio experience.
