Are wireless earphones able to deliver the same sound quality as wired?

Are wireless earphones able to deliver the same sound quality as wired? - Image 1

Plenty of people nowadays are searching for practicality when it comes to headphones but sometimes this level or convenience and lack of wires causes the actual sound quality to take a massive hit, or at least that’s what most people think.

Typically, most wireless options are in the form of Bluetooth earphones. When Bluetooth was initially developed it was not designed for use with audio equipment like headphones. It has a tight bandwidth that means when people started using it for transferring sound, the sound had to be compressed to be able to be sent in the first place.

This compression makes the quality of the audio lower than if you were to listen with a direct wired connection but with technology constantly changing and advancing things are always changing.

For instance, the recent technology called aptX was released. The whole purpose of this technology was to be able to deliver that same quality you get when you are wired in directly but only this time with Bluetooth.

How aptX works is basically it uses a different compression technique which allows for transmission of a higher quality audio output one which they say has a CD like audio quality. Though because it’s a newer technology it means not many devices has the functionality and if you do find a device which offers it you also that the phone/tablet or whatever you are using it with to be functional with it too.

Also as Bluetooth continues to be updated with newer versions this audio quality and general connectivity continues to improve with each update. Bluetooth started with version 1.0 and now we are all the way up to version 5 being the newest with a host of updates in-between. Though the newest version is only starting to roll out on the newest devices like the Samsung S8. One of the main benefits of Bluetooth 5 is an improvement of double the top transfer speed. This element alone could improve listening but we will have to see as time progresses.

Though a lot of people look directly at the Bluetooth functionality there are also a lot of other factors to consider that can affect the sound quality. The devices which are being used can be called into question, if they are poor quality earphones, if the audio source isn’t high quality itself and even the distance from one device to another should be considered.

Overall wired earbuds offer better sound quality that is more consistent than their wireless counterparts but as technology advances and consistently improves that may not be the cause for much longer!
