It happened to you that your headphones take time to connect to
Bluetooth? Or that you receive a call that you cannot answer because you are connected to a speaker? And what about when you want to watch a movie with your partner in an airplane without sharing headphones?

Bluetooth Special Interest Group (BSIG), the business association that controls the standards of this wireless connection technology, believes it has solutions for these problems.

This Monday,
the board of specialists of the BSIG gave details about the new version of the
Bluetooth, LE Audio, at the Consumer Electronics Show (
CES 2020), the world's largest technology fair in Las Vegas.

The specialized media catalog it as
one of the most important advances since 20 years ago This technology was created.

"With nearly a billion Bluetooth audio products marketed last year, wireless audio is the largest Bluetooth market," said Mark Powell, executive director of BSIG.

"The launch of LE Audio is an excellent example of how the Bluetooth community drives technology and product innovation and allows the delivery of even better and more capable Bluetooth audio products."

The new launch promises progress in
four different aspects: multiplicity of destinations, connection, audio quality and help for the disabled.

1. One issuer, multiple destinations

As part of the Bluetooth advancement package launches the
Broadcast Audio, a technology that allows users and developers
connect more than one device to an audio source.

For example, that several cell phones connect to the same speaker. Or vice versa, several headphones to the same tablet. With this you will not have to have two speakers of the same brand to be able to match them, and increase the volume and improve your party. This also allows the audio of a TV in an airport to be heard from your headphones and those of other people at the same time.

"The
location-based audio sharing it has the potential to change the way we experience the world around us, "said Peter Liu of the Bose audio company and a member of the board of directors of BSIG.

"Places like theaters and conference rooms can share audio to help visitors with hearing problems and provide audio in several languages," he added.

2. Connection and multiplicity of sources

Part of the reason why it is sometimes slow to connect wireless headphones is that the Bluetooth source only allows a connection, then it must first be linked to a headset and then they must be linked through an alternative system.

For that Bluetooth launches the
Multi-Stream Audio, a technology that allows a single source, such as a cell phone,
stream synchronized audio to multiple devices at the same time.

That makes it easier to connect fully wireless headphones, but also that you can
connect the same headphones to several different devices, like a tablet, a phone and a computer.

With that, if you get a call when you're listening to music on a speaker, you won't have to disconnect to answer it.
