How Do Bluetooth Speakers Work

Everyone uses Bluetooth nowadays. From home appliances to office equipment, this technology connects devices over short distances. As such, there are many advantages to using it for both consumer and industrial devices.

Once Bluetooth Low Energy technology was developed, it increased Bluetooth applications beyond audio streaming. Now, Bluetooth fulfills its promise of delivering a general-purpose connectivity solution. So, what is Bluetooth and how do Bluetooth speakers work? 

Read on as we fill you in on everything you should know about this wonderful technology!


What Is Bluetooth?

In order to understand how Bluetooth works, you must first know how we use phones to converse with one another. Cell phones use radio waves to communicate with cell towers that can be located as far as several miles away. For its part, Bluetooth is using radio waves that are much more weaker, which in turn means that Bluetooth range does not exceed 30 feet or 10 meters.

For example, a Bluetooth speaker should be within a few feet to an audio streaming Bluetooth device in order to work. The most advanced Bluetooth devices used for industrial purposes can have a range of about 100 meters (300 feet). But, you will not find such a range in any consumer device.


How To Connect Two Bluetooth Devices Together

It is easy to syncronizing Bluetooth compatible devices together. The connection is established automatically once you activate these Bluetooth devices within range. The communication between them occurs over a piconet, which is a short-range network and can comprise of multiple Bluetooth devices.

Once you have two Bluetooth devices within a single piconet, they will connect automatically every time they are able to communicate. One of them will act as a discoverable device and the other will work as a control center. That is how your Bluetooth keyboard and mouse become automatically available when you start your laptop and you can change their properties and settings.

So, in essence, Bluetooth is not only a communication technology. Just like other wireless technologies, Bluetooth offers data transfer capabilities. Otherwise, your Bluetooth speaker wouldn’t be able to play audio.

As explained above, wireless audio streaming is essentially the transfer of data between a streaming device (phone or computer) and a Bluetooth speaker within range. Hence, Bluetooth does indeed use data. 

One major advantage of using a portable Bluetooth speaker is that the user doesn’t require any tech skills. Simply switch on a Bluetooth speaker. Once your audio device discovers the Bluetooth speaker, the two devices will sync with each other.

The limited range of Bluetooth is also an advantage in this scenario as it prevents transmission of huge amounts of data over large areas and distances. This can disrupt the functioning of other connected devices and networks.

On the other hand, Bluetooth offers extremely low power consumption. This is because the transfer speed of Bluetooth networks is not very high. The same, of course, applies to other Bluetooth-enabled devices such as keyboards, mouses, keyless door locks, smartwatches, printers, webcams, and headphones.


Best Bluetooth Speakers To Consider Buying

The rapid advancements in audio streaming technology and the boom of music-streaming online services are making Bluetooth speakers one of the most popular Bluetooth devices. We have curated 3 of the best Bluetooth speakers available in the market for your consideration.

Sony SRS-XB501G is one of the big-sized party speakers on the market for wireless devices of this kind. It can play at full volume for up to 16 hours and you can control it through Google Assistant. It is an amazing party speaker to use on the go as its batteries last for 12 hours even with Extra Bass and lighting enabled.

You can control all the major features using the speaker’s buttons but you still need to install the Google Home app and Sony’s Music Center app to unlock the speaker’s smart functionalities.

The XB501G model is one that actually bridges the gap between a party and home speaker although Sony should put some effort into improving the voice detection capabilities of the device. Actually, average voice detection is one of the few shortcomings of the Bluetooth-enabled XB501G along with subpar app experience.

Nonetheless, it offers powerful sound for between 12 and 16 hours and has physical control buttons. The Sony SRS-XB501G portable Bluetooth speaker weighs 2.72 kg. That is why it is equipped with a sturdy carrying handle.

Final Thoughts

Bluetooth devices such as home and party speakers are getting increasingly popular thanks to a large number of advantages that Bluetooth technology provides.

It offers a very stable network connection. Also, while Bluetooth range is usually up to 10 meters (30 feet), the network does not interfere with other devices that transmit radio waves.

Bluetooth technology might not be suitable if you are required to set up speakers far away from the audio source. In this scenario, use cables is your best option. If you are in the market for an extension cord, we highly recommend the universal power strip from Krieger. It comes with 6 universal outlets and accepts most plug types from all over the world. Krieger universal power strip is available on Amazon for $19.97 and comes with free shipping for orders above $25.

Bluetooth technology is also relatively cheap to embed into a variety of products ranging from smart appliances to cars. Paired Bluetooth devices can also transfer data between each other and connect automatically once a discoverable device is within range. Bluetooth technology is also very suitable for installing beacons that interact with consumers passing nearby or provide information to visitors at a certain location.
