Audeze LCDi3 are ultra high performance planar magnetic earphones with great connectivity: the include a 3.5mm plug cable, a lightning cable for iphones and a state of the art bluetooth cable.
LCDi3 are open back, so they do not isolate and are not meant to use on a plane or where you need isolation. They are more like a compact, tiny headphone. LCDi3 use a lightweight magnesium housing like the flagship LCDi4 model, along with Audeze's patented voice coil and Fluxor magnets to provide outstanding dynamics and sound quality.
New ear tips and improved ear hooks provide a more stable fit. The Bluetooth cable uses BT5, apt-xHD and Audeze's DSP to provide great wireless sound quality with your phone. LCDi3 are easy to drive, with a low impedance and high sensitivity = good results with a huge range of sources.
