The Rockboard HA 3 is a handy little amp for anyone needing basic in-ear monitoring. It’s a great budget-friendly option for keyboardists, singers, or guitarists who want a clean, simple signal without needing a full-blown mixer. Just be aware it’s not a powerhouse, so IEMs with higher impedance might struggle.

Frequently Asked Questions
While technically possible, the HA 3's limited power is best suited for in-ear monitors. High-impedance headphones will likely sound weak and lack dynamic range.
It's a standard locking mechanism, so it should be compatible with most common XLR cables. However, extremely thick or unusually shaped cables might experience fit issues.
It’s a straightforward left/right balance adjustment, solely affecting the relative volume of each channel; it doesn't impact the overall output level.
