Imagine the convenience of effortlessly switching between your phone and computer audio without disconnecting and re-pairing your Bluetooth headphones. This dream is now a reality thanks to Bluetooth multipoint, a game-changing feature introduced with Bluetooth 4.0 in 2010. Initially, multipoint revolutionized workplace communication by allowing headsets to seamlessly switch between incoming calls on two phone lines. However, multipoint’s capabilities extend far beyond call centers, offering versatility for various devices and applications.
To understand multipoint, we need to grasp the fundamentals of Bluetooth. Essentially, Bluetooth creates a wireless network called a piconet that connects your headphones (Device A) to a Bluetooth-enabled source like your phone, tablet, or computer (Device B). In this setup, the headphones control the piconet, dictating volume, responding to voice assistants, etc., while the source device simply follows the headphones’ commands.
Multipoint enters the picture by allowing Device A (the headphones) to connect to two or more Device B (audio sources) simultaneously. This enables effortless switching between connected devices, keeping you connected to both your phone and tablet, for example, without needing to manually disconnect and reconnect.
There are three primary types of multipoint audio:
1.
Simple Multipoint:
The most common type, allowing connection to two sources at once.2.
Triple Multipoint:
Less common, but capable of connecting up to three audio sources to a single set of headphones or earbuds. The Technics EAH-AZ80 is a great example of triple multipoint.3.
Advanced Multipoint:
Similar to simple multipoint, but with an added feature that allows the headset to handle two calls simultaneously, placing one on hold while you attend to the other. This is typically seen in call center settings.Beyond these standard multipoint types, companies like Apple, Samsung, and Google have developed their own versions of automatic device switching. Apple’s automatic audio switching, for example, allows seamless transitions between your iPhone, iPad, and Mac using AirPods Pro. Samsung’s Galaxy Auto switching, via the Wearables app, similarly remembers your paired devices and automatically switches when a call comes in or music starts on another device. Google’s Fast Pair and audio switch features on Android enable similar effortless switching between compatible devices using Google Pixel Buds Pro.
The primary advantage of Bluetooth multipoint is its ability to connect a single set of headphones or earbuds to multiple devices simultaneously, allowing you to switch between them without manual intervention. But how does the system decide which audio takes precedence?
Consider a scenario where you’re wearing Sony WH-1000XM5 headphones connected to both your iPhone and your work computer. In general, the following hierarchy applies:
1.
Phone and video calls:
Take priority over voice assistants and system sounds.2.
Voice assistants, device alarms, and notifications:
Prioritize over audio from streaming services like Netflix and Spotify, as well as downloaded music or podcasts.Let’s imagine you’re at work, wearing your headphones connected to your iPhone and computer. You’re in a Teams video call on your computer when a text message notification from your partner reaches your headphones. You ignore it, but then your phone rings. Answering the call mutes the Teams audio while the phone call takes precedence. Upon ending the call, the Teams audio resumes.
Similar scenarios apply with Spotify music playing on your computer while notifications from your phone come through. The music pauses for the notification, then resumes. If a phone call comes in, the music pauses again, and resumes when the call ends.
While this seamless switching is ideal, several factors can affect the process. Device capabilities, compatibility, and settings configuration all play a role. For example, while music may pause for a notification or call, it might not automatically resume. You may also need to manually reactivate the microphone after a call. Despite these minor imperfections, Bluetooth multipoint remains a powerful technology offering convenience and ease of use.
When shopping for Bluetooth multipoint products, consider:
1.
Usage scenarios:
Are you looking for headphones for exercise, earbuds for commuting, a speaker for home use, or a car kit for hands-free calling?2.
Automatic switching:
Do you prefer seamless switching between devices or manual control?3.
Compatibility:
Ensure the product is compatible with your devices.4.
Key features:
Easy pairing, sound quality, battery life, build quality, and manufacturer support are crucial.5.
Reviews and research:
Read reviews and test the product if possible.6.
Budget:
Determine your budget and prioritize essential features.By carefully considering these factors, you can make an informed decision and enjoy the benefits of Bluetooth multipoint technology.
