How Do Wireless Bluetooth Hearing Aids Work?

Bluetooth Hearing Aids

Rapidly advancing technology has enabled those suffering from hearing loss to take back their independence. 

If you’re experiencing hearing problems and are looking for a solution, Bluetooth hearing aids may help you enhance your listening while providing direct streaming to your most commonly used electronics. 

This article examines how these Bluetooth-compatible hearing aids work, their advantages and disadvantages, and addresses some of the most commonly asked questions related to the technology.

Key Takeaways

What Are Bluetooth Hearing Aids and How Do They Work?-

Bluetooth hearing aids function as sound amplifiers for individuals with hearing loss while simultaneously allowing them to remotely connect to nearly any Bluetooth-enabled technology within range through a wireless platform. 

Most Bluetooth hearing aids can directly link to audio devices like cell phones, TVs, and other Android or IOS technology.

What Is the Advantage of Bluetooth Enabled Hearing Aids?

Advantages of Bluetooth Hearing Aids

Bluetooth-enabled hearing technology provides a modern alternative to the established sound amplifying technology. Beyond this, they offer distinct advantages over what some may consider outdated standard hearing accessories.

Improved Sound Quality

Connecting directly to your audio devices, Bluetooth hearing aids act similarly to headphones, streaming audio and eliminating the need for actions that may interfere with the quality of the sound they transmit, like putting your cell phone to your ear. 

Depending on the type of traditional hearing aid used, this could cause whistling or scratching noise, as well as difficulty finding the correct position for your phone’s speaker [1].

The technology is especially beneficial for people who like listening to music, vastly improving their listening experience. It enables a direct connection to most audio devices while eliminating unnecessary background noise [2].

Improves Noise Reduction and Sound Localization

Individuals making use of hearing aids due to hearing loss often experience a lack of audio localization, making it difficult for them to analyze their surroundings and focus on group conversations [3].

Certain hearing aids can help reduce background noise and improve audio signal localization, better mimicking the hearing abilities of those not suffering from hearing loss.

Control Your Hearing Aids Remotely

Hearing aids that function through Bluetooth connectivity typically come with a simple remote or smartphone installed application that allows you to remotely control your hearing aid volume, switch streaming devices, and connect or disconnect from various audio sources. 

Connect to Multiple Devices 

Instead of having to remove your hearing aids to listen to music or make calls, only to have to put them back on when you want to watch TV or join a conversation, Bluetooth hearing aids can connect to multiple electronic devices at once and switch seamlessly between them with the click of a button.

Technology capable of connecting to a Bluetooth hearing aid include [4]

  • TVs
  • iPads
  • iPods, including the iPod Touch
  • Any Bluetooth enabled music player (including modern car radios)
  • Android smartphones
  • Android tablets
  • iPhones
  • Other Bluetooth audio accessories (using either an IOS or Android platform)

This allows the individual to switch between phone conversations, music streaming platforms, and watching TV in seconds without reconnecting each device. 

Less Hassle to Wear

For people who spend a lot of time talking over their mobile phone or participate in sport during which they listen to music, Bluetooth hearing technology can be beneficial as it eliminates the need to remove and replace them repeatedly [5].

Many newer models are far less conspicuous, which could be advantageous for young people who could feel self-conscious while wearing them.

It’s estimated that hearing loss affects about 15% of the US adolescent population, with only obesity being more prevalent

What Are the Disadvantages of Bluetooth Enabled Hearing Aids?

Despite their overall benefits, Bluetooth hearing aids may have several disadvantages related to their connectivity and higher prices.

More Expensive 

Good-quality Bluetooth hearing aids can cost anything between $700 and $4000 each, which is substantially pricier than standard devices.

Manufacturers of hearing aid technology are actively attempting to make their Bluetooth-enabled devices more accessible to all budgets. Despite this, they are still more expensive than standard hearing aids. 

Drain on Battery Life

Hearing aids reliant on Bluetooth connectivity can quickly drain the battery of the accessories they are connected to, while frequent streaming could do the same to your hearing aid batteries [6].

Ideal standard hearing aid batteries could last up to 132 hours before needing replacement, while Bluetooth ones could run out long before that [7].

The hassle of replacing batteries every four to five days, along with the expenses of doing so, could become a frustrating disadvantage.

Requires Additional Accessories 

Some hearing aids may intermittently disconnect from some or be unable to connect to specific audio devices. To prevent this, users may need to purchase a streamer, which links the hearing aid and wireless technology. 

Streamers can link multiple electronic devices to your hearing aids through an FM signal.

Having to purchase and carry around extra accessories to ensure your hearing aids work may be a nuisance.

What Are the Best Bluetooth Hearing Aids?

There are many hearing aid brands out there, and deciding which one is right for you could seem overwhelming. Some of the best hearing aids that are Bluetooth enabled are described below.

1. MDHearingAid CORE

As one of the best Bluetooth hearing aids on the market, the MDHearingAid Core is a high-quality device that provides several beneficial features such as:
