Full-size open headphones with branded "monitor" sound and a very light folding design (weight about 170 g), which makes them an excellent option for home and outdoor use. Large leatherette ear pads completely cover the ears, giving decent passive noise isolation and comfort even with long-term use, and the titanium diaphragm of the drivers provides clear, surround sound with pleasant bass processing and detailed tops.
