Can Hush Stream Music From My Smartphone?

Hush is a smart earplug that is designed to protect your sleep throughout the night and in order to get meaningful battery life with our miniature ergonomic form factor, we had to limit what Hush could play. Currently hush can only play preset soothing sound tracks.

What if Hush is Uncomfortable For Me?

We’ve implemented many features that should make sleeping with Hush a pleasant experience, including an ultra-thin design and a variety of tip options (memory foam, silicone, custom molds). All ears are shaped differently though and we can’t guarantee that Hush will be comfortable for everyone. So, once we ship the product, we will have a 30-day return policy.

Does Hush Provide Active Noise Cancellation?

Hush reduces sound in two ways:

  1. The sound eliminating foam provides passive noise reduction as a first sound barrier.
  2. The in-ear speaker plays a track to mask any residual sound that the earplugs do not block out.

We combine these two time-tested popular approaches to dealing with noisy sleep environments. Active noise cancellation is a technology that is not generally effective at canceling out the sudden sounds that are most responsible for disturbing your sleep at night. That is why we do not use active noise cancellation but use the combination of two other effective means of noise isolation.

How Does Hush Deal With Radiation?

Hush achieves ultra-low radiation exposure because we do not stream audio throughout the night. Instead, Hush plays back audio files stored in the earplugs. Over the entire night, users are exposed to a fraction of what business professionals using Bluetooth® headsets are exposed to during a single phone call.

How Do You Clean Hush?

All of our tip options can be wiped down with a damped cloth or be replaced. The tips should be swapped as often as your hygienic tolerances allow – e.g. we personally replace the foam tips weekly however some people use the same foam for months on end.

If the Earplugs Fall Out While I Sleep, Will I Still Hear My Alarm?

The earplugs should not fall out if the correct sized tip is used and inserted correctly.* However, in the chance that both fall out, the earplugs will know because the user will not turn off the alarm. After three attempted one minute alarms within Hush, the system will sound the smartphone’s alarm. The user will then be able to hear the alarm through the smartphone’s speaker.
*See the Hush user manual for proper fitting of the earplugs.
