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).
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.
The device can connect at a greater distance via Bluetooth or infrared to another device.

Identical to QC45 except for soft carrying case

Manual refers to the headphone as QC45. When connecting to it from phone, it is also called QC45

Good sound quality but squeezes my head.

Je l’ai prit par e qu’il est moins chère que le QC 45 et qu’il semblait équivalent ! Et en effet c’est une copie du QC 45 ( c bizarre que bose sorte 2 casques identiques ) pour 200€ pas sur qu’on puisse trouver mieux ailleurs
