# CES Ultra > CES Ultra is a cranial electrotherapy stimulation (CES) device for the management of anxiety, insomnia, depression, and pain. Distributed by Miridia Technology. CES Ultra delivers gentle, sub-perceptible electrical current through clip-on earlobes electrodes to stimulate the brain's neurotransmitter production. Cranial electrotherapy stimulation (CES) is an FDA-cleared treatment modality used by healthcare practitioners and patients for relief from anxiety, insomnia, depression, and pain. CES works by delivering a mild alternating current (typically less than 1 milliamp) through electrodes clipped to the earlobes. This stimulation is believed to promote the production of serotonin, beta-endorphins, and other neurochemicals associated with relaxation and well-being. CES Ultra is distributed by Miridia Technology, based in Meridian, Idaho. ## Key Features - FDA-cleared cranial electrotherapy stimulation - Treats anxiety, insomnia, depression, and pain - Sub-perceptible current — patients feel little to nothing during treatment - Earlobe clip electrodes for easy application - Portable, battery-powered device ## Resources - [CES Ultra](https://cesrelief.com): Product information - [CES Ultra Articles](https://www.miridiatech.com/news/category/ces-ultra/): Blog posts about CES therapy - [Miridia Technology](https://www.miridiatech.com): Parent company - [Contact](https://www.miridiatech.com/contact): Support and inquiries
