How Do Wireless Bluetooth Earbuds Work?

Wireless earbuds have become all the rage these days, and with good reason. They’re easy to carry around, and since they’re wireless, you don’t have to worry about continually untangling the wire.

In addition, not only do they provide the best listening experience, but they’re also quite simple to use. All you need to do is connect your earbuds to your device, and you’re all set.

If you’re still a little doubtful about how earbuds work, this post will clarify all your confusion.

We’re going to go into details about how Bluetooth wireless earbuds work. In addition to this, we’ll be providing you a few tips that will help you find the best audiophile wireless earbuds.

So, let’s get right into it. 

Types of Wireless Earbuds

With the popularity of wireless earbuds, you’re going to see a wide range when it comes to wireless earbud technology.

Don’t fret, though. We’re going to explain the different types of earbuds terminology for you—this way, you’ll be able to find the perfect pair of audiophile wireless earbuds.

●     Infrared Earbuds

Infrared technology transfers data through electromagnetic waves. This technology cannot work if there are any barriers between the transmitter and the receiver. It is so common that even your TV remote also has it.

With infrared earbuds, you’ll find two types based on how they transmit signals:

  • Single-channel: These earbuds allow only one audio signal to be transmitted at a time.
  • Dual-channel: This type enables two audio signals to be transmitted at a time without interruption.

In addition, infrared signals have a range of 33 feet.

●     Radio Frequency (RF) Earbuds

On the other hand, radio frequency earbuds transmit sound from the transmitter to the earbuds using a stereo frequency modulation system. These earbuds come with different frequencies ranging from 900MHz to 3.2GHz, depending on the specific model.

Not only does this allow you to connect for a maximum distance of 300 feet, but you can also connect up to 100 earbuds to one radio frequency transmitter. However, the biggest disadvantage is that the connection can be interrupted quite easily.

●     Bluetooth Wireless Earbuds

You’ve probably heard a lot about Bluetooth Wireless Earbuds, as most wireless technology - be it earbuds or otherwise - usually uses Bluetooth technology.

So, what exactly are Bluetooth earbuds?

With one of the most common wireless technologies, audiophile Bluetooth earbuds come with a low frequency of 2.4GHz. In addition, Bluetooth 4.0 provides users with a maximum range of 33 feet, while Bluetooth 5.0 gives users a range of more than 100 feet.

For instance, earbuds like ReduxBuds come with Bluetooth 5.0 technology, which gives you an uninterrupted listening experience with great connectivity. Moreover, it can maintain a stable connection over long distances as well.


Now that we’ve established the different types of audiophile wireless earbuds, let’s take a look at how exactly these Bluetooth earbuds function without wires.

How Do Wireless Bluetooth Earbuds Work?

Bluetooth operates at a frequency of 2.4GHz and works over radiofrequency. What this essentially means is that the signals can transmit easily without any interruption from other radio frequencies.

Each Bluetooth device has a unique address that allows it to connect to other Bluetooth devices. While Bluetooth technology provides smooth and stable connectivity, you can only connect to devices that are compatible with Bluetooth.

How to Connect Wireless Bluetooth Earbuds to Your Device?

There are three main steps when it comes to connecting your audiophile Bluetooth earbuds to your smart device:

Step One - Inquiry

If this is the first time you’re connecting your Bluetooth earbuds to your device, you need to run an inquiry to connect the two devices. Essentially, the two devices discover each other through their unique addresses in this process. You send out an inquiry request from one of the devices, the other device responds to this inquiry by sending out its unique address.

Step Two - Paging

You can only proceed to this step after the two devices have discovered each other. This step is quite simple. All you need to do is initiate the connection using the unique address and then accept to pair the devices.

Step Three - Connection

Once you’re done with the paging process, your device can begin the connection stage. When connected, there are four main modes your device can be on:

  • Active Mode

When your phone is in this mode, it will transmit signals actively.

  • Sniff Mode

This mode allows you to use the Bluetooth at set intervals. It acts as a power-saving mode. Your device is also less active when on sniff mode.

  • Hold Mode

With this mode, you can temporarily put your Bluetooth connection on hold for a set time. You can set up the desired time you want your Bluetooth to sleep and when you want it to resume activity.

  • Park Mode

This is the deep sleep mode, where your Bluetooth connection remains inactive until you activate it again.

How to Connect to Bluetooth Earbuds?

  • First, you need to ensure your device is compatible with Bluetooth.
  • Next, enable the Bluetooth on your device.
  • Switch on your wireless Bluetooth earbuds and search for their Bluetooth address on the device you want to connect with.
  • Once you’ve found the address, tap your earbuds to connect. Usually, you’ll hear a sound, indicating that the connection has been established.
  • In some cases, depending on the model, you might be required to enter a passcode. You can find this passcode in the user manual of your earbuds.

How Do Bluetooth Earbuds Convert Digital Signals to Audio?

You’ve probably wondered how digital signals convert to audio, especially when there are no wires involved.

Well, let us explain in simple terms.

  • The process begins when your device (smartphone, laptop, tablet, etc.) sends a digital signal to your earbuds.
  • As wireless earbuds cannot play digital signals, your earbuds convert the digital signals to analog music using a digital-to-analog converter.
  • The digital-to-analog converter sends this newly converted analog music to the amplifier of your earbuds.
  • The amplifier then transmits the music to the speaker, which plays the audio you hear.

Wired Vs. Wireless: Which Option Should You Pick?

You’ve probably stumbled across more than one debate about which one is better; wireless earbuds or wired earbuds. Honestly, it depends on your preference. However, after looking at some of the pros and cons of both, we’re leaning towards wireless earbuds.

If you’re having a hard time deciding, just take a look below and judge for yourself!

Wired Headphones


  • High Sound Quality - Usually, wired headphones have better sound quality as signals are directly transmitted through a wire. You don’t have to worry about interference.
  • Easy to Use - Connecting and using these is really not difficult, all you need to do is connect the earbuds through the audio jack, and you’re all set.
  • Don’t Need a Battery - You don’t have to worry about charging your earbuds all the time, as they don’t require a battery. You can use them all day long if you need them.


  • Wire Is Inconvenient - Not only is it annoying to constantly untangle the wire, but the wire is also limiting. If you’re listening to music while using your laptop and if you have to move, you’ll need to either take off your headphones or carry the device with you
  • Wire Might Break - Wires breaking or getting damaged after getting tangled up or getting stretched is quite common. A damaged wire might cause you to say goodbye to your earbuds before time.

Wireless Headphones


  • No-Hassle - Thanks to wireless earbuds, you no longer have to struggle with tangled wires and cords.
  • Comfortable - In addition to losing the wire, wireless earbuds come with enhanced ergonomics that make them more comfortable.
  • Easy to Carry - Most wireless Bluetooth Earbuds are quite easy to travel with. For instance, ReduxBuds come with a carrying case, which also acts as a power bank. So, you can easily carry and charge your earbuds without much worry.


  • Limited to Bluetooth Compatibility - The biggest limitation is that these earbuds can only work on devices that are compatible with Bluetooth. However, given the advancement in technology, we doubt you’ll run across this problem.

Things to Consider When Purchasing Wireless Bluetooth Earbuds

When purchasing audiophile Bluetooth earbuds, here a few things you should take into consideration:

Battery Life

This is very important; you don’t want to invest in a pair of earbuds that will only last you for a few hours. We suggest looking into how long the battery can last and how long it takes to recharge. Certain earbuds, like ReduxBuds, offer users up to 100 hours of battery life.


So, we really suggest digging deep and finding out how much battery life a particular pair offers.

Bluetooth 5.0

If you’re investing in a new pair of earbuds, you might get ones with Bluetooth 5.0 technology. Not only is the quality great, but there are no interrupts amidst transmissions.

Water Resistance

If you enjoy singing in the shower or living in a wet climate, we suggest getting water-resistant earbuds. For instance, ReduxBuds come with IPX5 water resistance, which can resist low sprays of water, adding to your earbuds' safety.


Whether you’re a tech expert or not, once you read through our post, you’ll have no trouble figuring out how wireless earbuds with Bluetooth feature function.
