The KSC35, an ear-clip headphone from the American audio brand KOSS! While the KSC75 is available domestically, this model is not widely distributed! The lower number might suggest it's a lower-end model, but it's actually priced higher. The KSC75 features a titanium-coated driver from the Porta Pro, whereas this model uses the standard Porta Pro driver. Also, the ear clips on the KSC75 are more comfortable due to their resin covering. However, please understand the higher price due to limited availability. Even so, it delivers the reliable Porta Pro sound, allowing you to enjoy music with powerful bass! Recommended for those who love the Porta Pro sound but can't wear the headband! #KOSS #KSC35
