These powerful Fontopia headphones offer superb sound quality. The closed earphone structure, utilizing ultra small 9 mm driver unit and soft silicon earbuds (Sx2, Mx2, and Lx2) enables powerful bass reproduction and clear treble, reproduced by the 400 kj/m3 high-power Neodymium magnet.
Complete with earphone holder, case and 1.0m extension cord, they provide a stable and comfortable fit with easy wearing thanks to the long bushing, and connect conveniently to any remote commander. The accompanying earphone holder and soft carrying pouch make them a handily portable set!
