These headphones break 

Conventional wisdom says that IEMs should be closed-back. That IEMs should be tuned to one sound signature. That IEMs should be plastic. The FiiO FH5s breaks with tradition. In fact, it shatters it. With a semi-open back design, on-the-fly tuning switches, and an aluminum-magnesium chassis, the FH5s offers an all-new IEM experience. 

Best in iconoclast

It’s one thing to stuff an IEM with a million drivers and another to equip it with good, high quality ones. The FH5s’ two dynamic drivers are coated in beryllium, a rare element that’s strong and lightweight qualities provide rapid bass response and velvety mid-range. The Knowles TWFK-30017 balanced armature is placed as close as possible to the sound tube for airy staging and dazzling extension. 

Suit your sound

Traditional IEMs confine you to one sound tuning, but what if you don’t like it? You’re stuck. The FH5s features three tuning switches--for bass, mid-range, and treble--that can be adjusted on the fly. Try the crowd-pleasing Harman Curve, the mid-forward vocal performer, the bass bump, or one of eight total combinations. Find the signature that suits your sound.
