 How do you know if your phone has the very important aptx HD technology, and here's how to activate it

The aptX HD audio technology was introduced by Qualcomm in 2018, and it is already present in dozens of phones on the market. In this guide, we explain in detail what aptx HD is and what it is for, what are the differences between it and aptX, and which phones you can currently buy aptx HD with. Let's go there!

aptX is a compression algorithm developed by Qualcomm to transmit sound with the best possible quality in the limited bandwidth of the bluetooth connection, that is, so that the sound quality is best when transmitted wirelessly to headphones or wireless speakers.

What aptX technology actually does is compress and then decompress the audio as it travels between a source device - a cell phone - and a receiver - a wireless headphone - so that the audio can be transmitted over Bluetooth without getting damaged, as shown on the aptX website.

In this way, aptX audio technology allows you to listen to music with headphones or wireless speakers in the highest possible quality. This phrase helps us confirm that no, it is not true that wireless headphones reduce sound quality.

What are the differences between aptX HD and aptX?

Aptx technology was born in the early 1990s, specifically, this compression algorithm is capable of transmitting sound in 16 bit / 48 kHz quality, at a bit rate of 384 kbps.

Time has passed and Qualcomm researchers keep working on this codec to improve it. 2016 arrived and came the aptX HD technology, capable of transmitting audio at 24-bit / 48kHz, at a bit rate of 576kbps. This technology also improves the signal-to-noise ratio, which translates into less background noise when transmitting audio.

In addition, aptX HD technology has been developed with low total harmonic distortion (THD) technology to enjoy music without interference. Ultimately, the aptX HD compression algorithm enables better quality wireless audio transmission, with less background noise and less interference than aptX technology.

Which cell phones have aptX HD?

There are over a hundred mobile phones with aptX HD technology to provide the user with the best possible quality when listening to music with their wireless audio devices. These are the most prominent phones:

ASUS Rog Phone 3

OnePlus 8 / One Plus 8 Pro

OnePlus Nord

Sony Xperia 1 II

Sony Xperia 5 II

Xiaomi Mi Note 10 / Xiaomi Mi Note 10 Pro

Huawei P30 / Huawei P30 Pro

We see brands like OnePlus, Huawei and Xiaomi are betting on aptX HD technology for some of their latest mobile phones. To see the rest of the smartphones using this compression algorithm created by Qualcomm, go to the aptX website.

Before saying we close the post, we encourage you to activate this audio codec on your phone if it is compatible. To do this, enter phone settings and activate developer options. Next, enter this menu, search for the "Códec de audio de Bluetooth" section and select the option "Qualcomm aptX HD Audio". Now, you can enjoy the best sound quality when listening to music wirelessly.
