Bluetooth is commonly used to transfer sound data with telephones (i.e., with a Bluetooth headset) or byte data with hand-held computers (transferring files). Bluetooth protocols simplify the discovery and setup of services between devices. [55] Bluetooth devices can advertise all of the services they provide. [56]
Bluetooth HID is a lightweight wrapper of the human interface device protocol defined for USB. The use of the HID protocol simplifies host implementation (when supported by host operating systems) by re-use of some of the existing support for USB HID in order to support also Bluetooth HID. Keyboard and keypads must be secure.
Active noise control ( ANC ), also known as noise cancellation ( NC ), or active noise reduction ( ANR ), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...
Anechoic chamber. An anechoic chamber ( an-echoic meaning "non-reflective" or "without echoes") is a room designed to stop reflections or echoes of either sound or electromagnetic waves.

The card is the first in the Sound Blaster series to use a 32-bit/384 kHz SABRE 32 Ultra DAC (ES9016K2M), along with a custom-designed discrete headphone amplifier (1 W output power and low output impedance of 1 Ohm so it can provide high damping factor for virtually any dynamic headphone).
Headphones that use cables typically have either a 1 ⁄ 4 inch (6.4 mm) or 1 ⁄ 8 inch (3.2 mm) phone jack for plugging the headphones into the audio source. Some headphones are wireless, using Bluetooth connectivity to receive the audio signal by radio waves from source devices like cellphones and digital players. [5]
