Frequently Asked Questions - soundKey Cyrus Audio

What is the Cyrus soundKey?

The Cyrus soundKey is a high-quality, in-line DAC upgrade for mobile devices and computers, encased in a solid aluminium body. It improves audio performance when listening with headphones.

Which Android devices are supported?

The soundKey works with Android mobile devices that are OTG (on the go) compatible. Use the supplied OTG cable: the grey plug connects to the device, the black plug to the soundKey.

How do I connect soundKey to an Apple device?

For Apple devices with a Lightning connector, you need an Apple camera kit (not supplied) to enable USB connection. Use genuine Apple camera kit references MD821ZM/A or MK0W2ZM/A, then connect the supplied USB cable to the soundKey.

Can I use soundKey with a computer?

Yes, it can be used with any laptop or desktop that has a USB port with specification USB 1.0 or later. Connect the supplied USB cable and set the computer's audio output to route through the soundKey if necessary.

Why doesn't the hands-free microphone work?

The soundKey is a high quality headphone upgrade and does not include connectivity for a hands-free microphone. It only routes audio to the headphones, so microphone functionality is not supported.

What causes occasional clicking noises?

Clicking sounds occur when the audio signal from the source is not stable, making the soundKey re-lock to the signal. Try using a different audio source for a more stable performance.

What is included in the box?

The package includes the soundKey, a USB connection cable, an OTG micro USB cable, an OTG USB-C cable, and a quick-start guide.

How should I clean the soundKey?

Clean only with a dry cloth. Do not use water, liquids, or cleaning agents, and do not use the apparatus near water.

What is the warranty coverage?

The warranty period is one year. Keep the sales receipt as proof of purchase. Claims should be made through the retailer; unauthorized servicing or damage may void the warranty.

Can I repair the soundKey myself?

No. There are no user-serviceable parts inside. Refer all servicing to qualified service personnel and do not attempt to open the device.
