Two pairs of headphones at a similar price can differ in battery life, noise canceling and weight, and buyers want those differences side by side. Accessories add a compatibility question, because a case, charger or cable has to work with the exact model the customer already owns.

Specs deserve a fixed place on every product page. Look for a Shopify theme that can display them as a table filled from metafields, Shopify’s structured product fields, so every listing follows the same format. Some themes add a comparison tool for products that differ by only a few specs. Warranty terms and a “what’s in the box” list answer questions that would otherwise arrive as support emails.

Accessories are the natural add-on, but automatic recommendations don’t know that a case fits only one phone model. Hand-picked complementary products, set up in Shopify’s Search & Discovery app, are safer, so check whether the theme can show them on product pages or in the cart. Deep electronics catalogs also need a mega menu and filters for storage, screen size or connectivity.
