Billie Jean is the latest collaboration of In-Ear-Monitors (IEMs) between Astell&Kern and Jerry Harvey Audio. Featuring a new Dual Balanced Armature (BA) driver system and patented freqphase™ technology, Billie Jean is equipped with an internal sound bore design that brings clear, impeccably balanced sound, resulting in a real audio experience that will take your music to the next level.
The new IEM shell has been optimized to fit nicely in the ear, while the 2-Way 2-BA design brings more power with less weight for efficient, yet powerful sound. The cable itself is manufactured from compressed, silver plated copper wire, which is then flattened and rolled into a steady interval and wrapped around Kevlar. This provides the cable with astounding tensile strength and delivers the full dynamic range of music. Conventional straight cables do not handle the frequent bending of cables and often short out, but Billie Jean's intertwined cable disperses the stress to the cable to offer enhanced, long lasting resilience.

The cable is detachable as it can be changed out. For example, a cable terminated in a different connection (3.5mm unbalanced jack or 2.5mm balanced jack) or a custom cable. They are not wireless earbuds.Do these have a microphone for voice calling?
The cable does not include a microphone for voice calls. The cable is detachable so if there is a cable that uses the same 2-pin connector and has a microphone it could be possible.Are they water resistant? Can I wear them while working out and sweating or will they short out?
Billie Jean In-Ear Monitors are not water-resistant/waterproof. However, the way they are made is to dodge sweat due to the length of the canal inside your ears. The IEM concept was originally for musicians, who sweat a lot. That being said, when sweating, don't take them out and put them in repeatedly because the sweat from the outside of your head could get inside the end of the canal.
