Debra Audio ST-MINI is a compact stereo wireless in-ear monitoring system with Type-C charging and rechargeable lithium battery, variable-frequency UHF transmission (claimed 11–16 channels) and a stated 30–50 m range. It’s targeted at performers who need a lightweight, multi-receiver-capable IEM link with manual channel switching, but reviewers disagree on battery life and channel/range specs, so expect some specification uncertainty.
For solo musicians or small ensembles needing a lightweight, stereo wireless IEM with manual channel switching; avoid if you need tightly verified specs or guaranteed long battery life.
