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.

Great headphone for the value.

Bought these for work. I operate heavy equipment, so lots of very loud background noise, and with this noise cancelling turned out, it does a very good on cancelling the noise for how loud the machine is. We are required to hearing protection. I may upgrade to the 910, or even xm4 one day, but on sale for 99 dollars canadian. You can't go wrong. They worked great in the gym, did not hear a single thing when the NC is on! Gets a little warm, but just take em off for certain workouts to keep your ears cool.

Decepción total

A simple vista se ven de lo mejor, lees sus especificaciones y piensas que son unos muy buenos audífonos, pero una vez que los tienes en tus pasos empiezas a decepcionarte, los plásticos son de lo peor, el sonido es plano en su totalidad, la cancelación de ruido es demasiado chafa, y lo peor es que a diferencia del modelo anterior este modelo no es compatible con la app de Sony, lo que significa que no contamos con ecualizador de audio nativo, lo cual le vendría muy bien si lo tuviera, ya que se podría solucionar el problema del audio plano.
