Headphones with Bluetooth are a great idea. The thought that you won’t be involved in pulling wires around when using Bluetooth headphones is amazing. Bluetooth is of several varieties we consider working range.

There are short and long-range working Bluetooth. If you are a genuine Bluetooth headphones user, you will notice that the blue light of your headphone’s Bluetooth goes off when you move a certain distance away from the other connected devices. 

Some headphones experience a break in communication at a certain distance, while others do so at longer or shorter distances. You probably did not know why and that is why you surely typed the question on google. You are at the right place, and we will give exactly the answer to the question you have been looking for. 

The range of Bluetooth connection is at about 10meters (30feet). Still, the maximum communication range depends on the electromagnetic environment, obstacles such as metals and walls standing in the way, and most importantly, on the class of Bluetooth in question.

Bluetooth headphones maximum range.

Bluetooth works on the same principles on all devices. The range of any Bluetooth depends first and foremost on the type (class) of Bluetooth you are using. There are three classes of Bluetooth, each working at a certain maximum range.

Before we continue, let’s clear away one misconception about Bluetooth. Bluetooth won’t be faster or slower when closer or far apart. Bluetooth is a wave, and like any other wave (short or long-distance wave), Bluetooth works well only within a specific range.

What are the classes of Bluetooth?

The range of a Bluetooth device depends on its class. You can pair two Bluetooth devices of different classes without difficulty. They will, however, default to the lowest class and its range limitations. Other factors, including interference and Bluetooth device location, can impact the overall operational distance of Bluetooth devices.

  • Class 1 Bluetooth: Class 1 Bluetooth Headphones range is 50-80 meters (164-262 feet). With high power and sensitivity, Class 1 Bluetooth can reach distances much beyond the standard 100m. However, it is also dependent on the device’s throughput requirements.
  • Class 2 Bluetooth: The power rating of a Class 2 Bluetooth headphone is 2.5mW. The operational range of these headphones is 10-20 meters. You can connect two devices of different classes. They’ll get the job done just fine. They will, however, revert to the lower class. A Class 1 headset with a Class 2 telephone, for example, will work up to 25-33 feet. Wireless headphones using Class 2 technology are the most widespread.
  • Class 3 Bluetooth: Class 3 Bluetooth, the shortest range of all, has a transmitting power of 1mW and operates at fewer than 33 feet (10meters).

Note: firstly, most headphones are class two Bluetooth devices.

Secondly, as mentioned above, the ranges are the manufacturers’ intentions and can be drastically altered (reduced) by obstacles such as walls between the two devices.

Therefore, the range is affected by obstacles, receiver sensitivity, and transmitting power.

What are the factors that affect Bluetooth range?

Transmit Power.

Consider transmitting power to be the same as the volume of your voice. The farther someone can hear you, the louder you speak, but it requires more energy.

When selecting a transmit power level, a design tradeoff between range and power consumption is made. As the transmit power increases, the likelihood of the signal being heard across long distances increases and the greater the effective range. 

However, raising the transmit power increases your device’s power usage. Bluetooth technology allows for transmission powers ranging from -20 dBm (0.01 mW) to +20 dBm (0.01 mW) (100 mW).

Sensitivity of the receiver.

Devices must reach a minimum receiver sensitivity of -70 dBm to -82 dBm, depending on the PHY employed, according to Bluetooth® technology. On the other hand, Bluetooth implementations generally attain receiver sensitivity levels of -95 dBm or better.

Consider the sensitivity of your receiver and how well you can hear or the quietest sound you can hear and understand. The least signal strength that a receiver can comprehend is measured by receiver sensitivity.

In other words, it’s the lowest power at which a radio signal can be detected, a connection maintained, and data demodulated.

Radio Frequency.

The radio spectrum covers a range of frequencies from 30 Hz to 300 GHz. The longer the range, the lower the frequency. However, the data rate depends on the frequency it can handle, the lower. As a result, choosing a radio spectrum requires balancing range and data rate.

The 2.4 GHz ISM radio band (2400 to 2483.5 MHz) is used by Bluetooth® technology, allowing for an excellent balance of range and throughput. Furthermore, the 2.4 GHz band is ubiquitous, making it a global standard for low-power wireless connections.

Other factors like the physical layer of the OSI model, path loss, and antenna gain all define a Bluetooth effective range.

How can you improve the Bluetooth range?

Get newer versions.

If you have an older Bluetooth device, the quickest approach to improving its range is upgrading to a newer one. An outdated version of Bluetooth on older devices may only allow you to connect devices up to 33 feet apart. Bluetooth will not connect if two devices are more than that distance apart.

However, if you choose Bluetooth 4.0 devices, you can range up to 100 feet. This indicates that you will have a strong signal beyond 30 feet.

When you have a new gadget, the signal will be weaker at 100 feet than at 50 feet, but you will still have a larger range. Most new products come with Bluetooth version 4.0 or 5.0, which are speedier and have a greater range. Bluetooth 4.0 has a longer range than previous Bluetooth versions and is safer.

Because they can connect over a great distance, these new Bluetooth devices are convenient. While driving, you can listen to music or make phone calls using an earpiece. Without wires, headphones and speakers now provide a better method to listen to your music.

 Avoid Physical Barriers.

Because Bluetooth, like Wi-Fi, relies on two-way radio transmission to function, any object obstructing the line of sight between the two connected devices reduces the connection’s effective range.

A Bluetooth signal, for example, travels further in an open space than in a crowded space.  Thick and heavy objects between the devices degrade signal quality; removing those barriers will improve the connection’s range. 

Repetition of Signals.

Install a Bluetooth repeater, which acts as a bridge between the two operating devices. The repeater should be within range of the least powerful device, but using the repeater gives the least powerful device a boost.

A headset with a 33-foot range connected to a 1,000-foot repeater, for example, will effectively have a 1,000-foot range


Bluetooth gives users the comfort of not having cables crossing here and there and having one stick to a particular place.

You can move about as you listen to your music. however, there is a certain range of distance within which you must work, and this distance depends on the class of Bluetooth you use.

The good news is that you can improve the operating range of your Bluetooth.
