This pair of Knowles CI-22955 Balanced Armature Receiver units is engineered for one purpose: to deliver exceptionally powerful and precise bass response in custom in-ear monitor builds. As the largest and most potent receiver in Knowles' acclaimed CI series, the CI-22955 bass driver transforms your audio experience with authoritative low-end clarity that you can feel.

    Beautiful dress
    Really happy with this purchase. I only wish I had steamed it before trying it on because it arrived with a few wrinkles from shipping.

    Worth every dollar
    The quality surprised me. The material has a nice weight and doesn't feel see-through at all. I'll definitely order another style.

    Runs slightly roomy
    I was between sizes and ordered the larger one. It still looked great, but I probably could have gone with my usual size.
