The development history of Bluetooth headphones

  • Author:Cindy
  • Release Date:2021-10-19

Bluetooth headphones  get rid of the shackles of wired, coupled with the removal of the 3.5mm headphone jack for Apple mobile phones since 2016, it has expanded the market for Bluetooth headphones.

Entering 2019, TWS true wireless Bluetooth headphones have experienced explosive growth. Let me explain the development history of Bluetooth headphones.




1. In 1994, Ericsson developed Bluetooth technology

The main purpose of Bluetooth technology research and development is to eliminate the traditional serial port data line (RS-232 interface) to provide a better information transmission method for its products.

2. Named Bluetooth by Intel engineers in 1997

In 1997, the word Bluetooth, which originated in Scandinavian, was proposed by an engineer at Intel and finally named Bluetooth as we know it today.

3. The first wireless Bluetooth headphones  came out in 2000

The first Bluetooth headphone uses the Bluetooth version 1.0. Due to the very limited bandwidth of Bluetooth 1.0, the voice can only be transmitted in mono. Although it can meet the needs of calls, it cannot be used to listen to music.

In addition, the first Bluetooth headphone is limited to headsets, and the purpose of its research and development is just to not disturb others when watching movies in the living room.

4. Stereo Bluetootsh headphone appeared in the following 10 years

Bluetooth technology has been continuously improved over the past 10 years, and finally stereo Bluetooth headphones appear.

However, after switching to wireless, the integration of the circuit in the earphone is greatly improved.

In addition to installing the Bluetooth chip, it is also necessary to provide enough space for the battery.

So for a period of time, headsets were still the mainstay.

Earbud headsets that are lighter and easier to carry have not yet appeared, and battery life was also an important constraint on the difficulty of Bluetooth headphones at that time.

5. Earbud headphones appeared around 2011

The earbud type earphone connects the earbuds on both sides with a short wire, and inherits the battery and circuit in the earbuds, and then adds the wire control function.

This kind of headset is light, easy to carry, and has good battery life, which greatly improves the consumer's experience, and it is still the mainstream product on the market to this day.

Earbud headsets have greatly improved in terms of sound quality, sound delay and battery life. The application of new coding technology has enabled the sound quality of Bluetooth headphones to reach the level of audio source playback that can support CD specifications or lossless specifications.

6. The first true wireless Bluetooth headphone appeared in 2015

The first true wireless Bluetooth headsphone in 2015 was the W800BT released by Japan's Onkyo at the 2015 IFA exhibition.

Then in 2016, Apple launched Airpods true wireless Bluetooth headphone.

7. Update Bluetooth 5.1 version in 2019

In January 2019, Bluetooth's governing body, the Bluetooth Technology Alliance (SIG), announced that Bluetooth 5.1, now available to developers, will bring enhanced location services to Bluetooth-enabled devices.

More than two decades have passed since 1994, although Bluetooth technology has received the impact of other technical standards.

However, during this period, Bluetooth technology has been continuously improved, and finally has the current Bluetooth 5.1 version.

Bluetooth technology is still one of the most important technical standards in the field of wireless communication technology.

Judging from the development history of Bluetooth headphones, the future development of Bluetooth headphones will also be improvements and enhancements in improving sound quality, battery life and sound delay. Of course, the implantation of smart AI in future headsets will become more and more common.
