Know before you buy
The UM Pro 50 uses five balanced armature drivers per ear, which are tuned for professional studio monitoring rather than casual listening. This design provides a much higher level of detail and a flatter, more accurate frequency response than typical consumer-grade headphones.
Yes, they are specifically designed for professional stage use. Their high sensitivity and effective passive noise isolation allow musicians to hear their own mix clearly even in loud environments.
Yes, the UM Pro 50 features a replaceable EPIC cable. This modular design allows you to swap out the cable if it becomes damaged, significantly extending the overall lifespan of the earphones.
With an impedance of 45 ohms, these earphones can be driven by most smartphones, laptops, and professional audio interfaces without needing a dedicated external amplifier. However, using a high-quality source will help you get the most out of the detailed driver configuration.
Passive noise isolation is achieved through the physical fit of the ear tips in your ear canal, which blocks out external ambient sound. Because these are designed for professional monitoring, they provide a very tight seal that is highly effective at reducing background noise.
The UM Pro 50 is designed with an ergonomic, low-profile shape that sits securely in the ear. While comfort is subjective, the lightweight construction and variety of included ear tips allow most users to find a secure, fatigue-free fit for extended studio or stage use.
