Your site width is minimum 1300 px but your image are getting rendered 750 px. That’s why it’s blurry.
I attached the image that is getting rendered.
Onionstrips_Merch_E-Shop_Website.png (750×422) (southdrops.eu)
vibe.jpg (750×422) (southdrops.eu)

This is not a theme problem, Shopify render responsive image means according to screen size the image will render. It’s good for optimization. But you can control it via liquid code.

If theme can render this size: vibe.jpg (1500×844) (southdrops.eu) then problem solved.
