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.

I really enjoyed these headphones. I've tried other models such as JBL, Sony, and Apple, but these headphones blew me away. I won't even consider the cost-benefit, because they're truly TOP notch! Very comfortable for long hours of use, like watching movies or listening to music for hours, in addition to very good sound quality. They have multi-point Bluetooth, which allows you to connect two devices at the same time. Ex. Tablet and Cell phone. There's a Philips app that you can download to your phone, allowing you to equalize the sound on the headphones. Very good bass output. 60h with a single charge! I've had them for over a year now and the only downside I can mention is that when you increase to the maximum volume through the headphones, it gives you an auditory warning (a beep). The problem is that the music lowers and this 'beep' comes, then everything increases all at once, causing major discomfort in the ears. However, if you increase the volume through the device itself, there's no alert (beep). Nonetheless, kudos to Philips for producing such excellent headphones.
