Review on 🎧 FiiO FA1 Over The Ear Earphones: Premium HiFi Single Balanced Armature Driver with Detachable Cable Design for iOS and Android - Blue(L) and Red(R)-Swirl by Greg Muin

White box with Knowles logo is very stylish. The included hard case is very professional and the headphones themselves look fantastic. The shape should offer above-average insulation for almost everyone. Knowles' full-range balanced armature doesn't have much sub-bass, but anything above 60Hz is just great. Edit: I used the included red tips and a FiiO E10 amp to boost the bass on them and they are very responsive. An equalizer is also an option, but this reduces overall clarity.
