The connectivity type of the headphones.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
aptx Adaptive is an audio codec for Bluetooth devices that is developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps), which means it can adjust the bit rate for different scenarios, such as listening to HD audio or reducing interference from other devices.
aptX is a codec used for transmitting audio wirelessly with Bluetooth. It is developed by Qualcomm, and supports 16-bit audio at a bit rate of 384kbps.
LDAC is a codec developed by Sony for Bluetooth audio. It is capable of a very high bitrate of 990kbps, which provides high resolution audio. It can also automatically adjust to a lower bitrate of 330kbps or 660kbps to increase stability.
aptX Low Latency is a codec developed by Qualcomm. It uses Bluetooth 5.0 technology to provide low latency audio (around 40ms), which is useful when you want to avoid audio lag (e.g. when playing games).
aptX HD is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 24-bit audio (at a bit rate of 576kbps).
aptX Lossless is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 16-bit/44.1kHz audio (at a maximum bit rate of 1200kbps). This codec provides CD-quality audio without any loss of data.
AAC is a codec that is used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.

Bang HX even better.

I already own the H9 and decided to get this one because I thought it would be decidedly better than the H9. It's not, at least not in sound. However, in terms of noise reduction, there is a significant improvement, but only for those who use them outside the house. For those who, like me, only listen to music, there's no difference. Both headphones are exceptional, and under 300 euros, they're great. Of course, the HX is more recent and has more usage options.

I only tested the HX for 5 minutes but that was enough to be 100 percent convinced about my next purchase... such a sound! And all that via Samsung tel a52 (which does stream Aptx at 44kHz) and bluetooth... so full... so balanced high/mid/low... for my fairly small ears it was very comfortable... and the noise isolation was already very good with the anc off (fits well)... conclusion a TOP SHELF PRODUCT!

Bang & Olufsen HX has an excellent sound and built in quality.It’s noise cancel.could be better.I’ve got an average ears size,still takes time to adjust the right position of the headphone circle shape.It’s size cold be bigger in mine oppinion…
