The brief this store was built from
Ninety Ohm builds desktop headphone amplifiers on the third floor of a former textile mill in Lowell, Massachusetts. Two people run it: a technician who spent nine years repairing hearing aids, and a machinist who cuts the enclosures from aluminium bar stock on a mill older than either of them. Every unit is bench tested for an hour, and the measured numbers ship inside the box on a printed card with the serial number written on it.
- Product
- Model One Desktop Headphone Amplifier, $289
- About it
- A single input desktop amplifier that drives headphones from 16 to 600 ohms without a gain switch, built on a through hole board inside a milled aluminium case. The volume control is a stepped attenuator with 24 positions, so the left and right channels stay matched at low listening levels instead of drifting apart the way a cheap potentiometer does.
- Brand facts
- Every amplifier is bench tested for one hour and ships with its own printed measurement card. Enclosures are cut from solid aluminium bar stock, not folded sheet, so the case is the heatsink. Through hole boards with a socketed op amp, so a repair is a screwdriver and twenty minutes.
- Style
- Tech Warehouse. Electronics marketplace — short hero, colored buttons
Who this theme is for
A hardware brand that sells on specification rather than mood. Audio gear, keyboards, cameras, test equipment, bike components, anything a buyer researches for a week before spending 289 dollars on it. The short hero gets out of the way after one screen, which is what a specification shopper wants, and the colored buttons make the one action on each page obvious without a second competing button beside it. It suits a shop with one to ten products and a lot to say about each of them.
What was decided in the brief
The style is Tech Warehouse on the cyan variant. Product photography for electronics is grey on grey, brushed metal on a seamless backdrop, so the interface carries the color instead: a saturated cyan primary against slate, with a rose accent used only on price and add to cart. Headings are set in a plain sans with tight tracking, because a serif on a measurement card reads as costume. The three brand facts sit under the hero as short lines rather than a paragraph, since testing, machining and repairability are three separate reasons to buy and a buyer checks them one at a time.
What is in the ZIP

- The whole store shell: product, collection, cart, search and 404 templates, header, footer, announcement bar.
- Valid Shopify 2.0 sections with schema, so every line of text is editable in the Shopify editor.
- The photos you see in the preview, ready to swap for your own.
Questions
- Is this Shopify theme really free to download?
- Yes. You get a complete Shopify 2.0 theme ZIP and no account is needed. In your Shopify admin open Online Store, then Themes, then Add theme, then Upload zip file.
- My product pages need long specification tables. Will they fit?
- Yes. The product description area takes ordinary HTML, so a table renders in place and scrolls sideways inside its own container on a phone rather than pushing the whole page wide. The rich text block in the theme editor accepts the same markup.
- Can I change the cyan to my own brand color?
- Yes. The palette is five settings in the theme editor. Change the primary and the buttons, the header, the links and the section rules all move with it, because no color is hardcoded in the CSS.
