DACs with Bluetooth interface

Bluetooth

— the device supports Bluetooth wireless technology. The main application of this technology in DACs is the wireless transmission of audio from an external Bluetooth device (smartphone, laptop, etc.) to the converter. Initially, such a transfer was associated with a loss of sound quality, but relatively recently, the aptX format has appeared, which allows you to transfer audio via Bluetooth without loss in quality. So when choosing a transducer with Bluetooth, it doesn't hurt to check if it supports aptX (and, of course, this standard must also be supported by the signal source).
In addition to broadcasting sound, there are other options for using Bluetooth — for example, using an external gadget as a remote control. However, they are much less common.
