The Super.Fi 4 in-ear headphones from Ultimate Ears provide the same high-quality sound that you'll find in custom in-ear monitors at a fraction of the cost. These lightweight earphones fit snugly in the ear, and a variety of eartips are provided so you can find the most comfortable, stable fit. A proper fit can help extend the bass response of the earphones, as well as reduce ambient noise by up to 26dB.
Each earpiece contains a single custom armature speaker designed to provide a full frequency response. It is specially tuned for detailed bass, while also delivering crisp mid and treble tones. A proprietary filter shapes the sound for maximized detail.
In addition to the spare eartips, an in-line sound level attenuator is included, ideal for reducing the volume of overly loud sound sources. A compact storage case is also provided that slips easily into your pocket or bag.
