Hi, I'm Ohr-1.
Push to start
01Turn on and off using the push button on the front.
Charging
02Charge via the USB-C port on the back of the Ohr-1. The Ohr-1 is fully compliant with the USB-C specification and can be plugged into your computer or a power adapter.
The Ohr-1's battery lasts for ~100hrs of continuous use.
Indicator Light
03There is a power indicator light in the bottom-right corner of the display.
Fast flash = low battery (~3 hours left).
Slow flash = charging. The indicator light will stop flashing when the device is fully charged.
Level Guide
04The Ohr-1's display turns red at 85 dB(A), the threshold for hearing damage. Above that, exposure time starts to matter. Every 3 dB halves the safe listening time.
The level you require will depend on the space you're in and its purpose. In a studio, holding a consistent level helps protect your ears and keeps your mixing decisions consistent across a session. At FOH, a club or venue will almost always exceed 85 dB(A). The Ohr-1 is useful for keeping inside a venue limit, or working at a fixed volume night to night.

Placement
05The Ohr-1 is versatile and can be placed in a variety of locations from FOH booths to studios & venues.
In studio settings, as a general rule of thumb, try not to place the Ohr-1 directly in front of monitoring speakers as this will cause the Ohr-1 to read higher than the room level. The Ohr-1 works well when placed on your mixing desk, adjacent to monitoring speakers or on top of monitoring speakers.
Device Care
06We have built the Ohr-1 to be rugged and durable, however we recommend the following care:
- Avoid liquid exposure.
- Avoid getting dirt and liquid into the microphone port (located on the top of the device).
- While the Ohr-1 can take a beating we recommend wrapping the Ohr-1 in something soft to avoid any light cosmetic damage when placed in a bag.
We are firm believers in right to repair. The Ohr-1 has been designed in a modular way that allows easy repair and replacement of components. We stock and sell all the necessary replacement parts for the Ohr-1, just get in touch!
