We are Shipping!

The first units went out a week ago, now we’re picking up speed.

Super quick update - stuff is going out the door now. There have been many, many small bugs to work out, but I think we have them all fixed. If all goes well, everything (speakers & kits from crowdfunding & pre-orders) will be shipped over the next two to three weeks. I’m going to be here at the shop a ton, but it’s great to have some work to do that is a little less brain intensive.

Logistics-wise: Crowd Supply is doing the actual shipping. You will receive an automated email from their system when your package is shipped. If your address has changed over the last few months and you haven’t contacted us yet, please do so ASAP to make sure we send your gear to the right place.

Thanks for waiting!

Product Choices



The Copper is a wired, powered speaker. It sounds great, and it looks killer - but it does have to be plugged into both power and an audio source. Includes power supply and 3.5mm cable - attach any device with a standard headphone audio output. Available in mono ($300) or stereo ($400). Stereo shown in image.


PILOT: Helium



The Helium is a capacitor-powered, portable wireless speaker. It charges in five minutes, plays for six hours at full volume, and sounds awesome. Includes Bluetooth receiver with Apt-X and AAC codecs, Fostex FE 126 driver, bamboo cabinet, and wall adapter. Built to last in Portland, OR.


EARLY: Helium



The Capacitizer is a DIY kit for building a capacitor-powered portable wireless speaker. Build your own enclosure for a high-efficiency driver, OR convert an existing high-efficiency passive speaker. Includes the assembled PCB, four 350F supercapacitors, a power supply for charging, hardware, and instructions. Tools and know-how required! Driver not included.


Double Down

A Helium Stereo speaker AND a Helium Mono for the ultimate listening experience.
