LDAC reception provides a high-resolution wireless option when a compatible source supports and enables the codec. SBC provides another Bluetooth connection path. The headphones’ published response extends from 20Hz to 40kHz, while the complete result still depends on the source, content and connection settings.\u003c\/p\u003e\n\u003ch3\u003eWireless And USB Audio In One Pair\u003c\/h3\u003e\n\u003cp\u003eBluetooth 5.4 provides wireless listening, and multipoint supports switching between two Bluetooth devices. For a computer or other compatible digital source, the supplied USB-C-to-USB-A cable provides a wired connection. Wired listening disables Bluetooth mode, so select the connection that matches the source you want to hear.\u003c\/p\u003e\n\u003ch3\u003ePause For A Conversation\u003c\/h3\u003e\n\u003cp\u003eIn Bluetooth mode, touch and hold the right ear cup to pause playback and let ambient sound through.

The published battery test uses SBC decoding at 50% volume. Codec choice, listening level, content and environment affect actual runtime; the figures are a guide for planning, rather than a guarantee for every combination.\u003c\/p\u003e\n\u003ch3\u003eSettings On Phone And Computer\u003c\/h3\u003e\n\u003cp\u003eUse EDIFIER ConneX on a compatible mobile device for supported settings, including LDAC and Touch-to-Chat controls.
