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.

Not a good fit for big ears.

All of the hype indicated these were a good choice if you had big ears, not so for me. Therefore if you can't get a good fit it's hard to say that they sound good and give good noise isolation / cancellation. In all fairness I must say that they were an exceptional build however.

Most crispy sound quality I’ve ever heard on a Bluetooth headset. ANC works well especially when playing music. Bass is natural and unfiltered. Sound separation is excellent for both music and video.
