I don't agree with the inverse. Bad speakers (eg laptops, especially Thinkpads) can make listening to good songs into a meh experience. It's better than nothing when you want music, but rarely will you notice that spontaneous feeling of love for what you're hearing. This doesn't justify the utterly diminishing returns of the audiophile world or the whole speaker cable nonsense, but paying something for a decent setup is worth it. Although from what I understand that effective price point is much lower with headphones compared to speakers.
For movies, I watched a cam rip once. The experience was so bad I vowed never again. And the weird bit is all the distortions were like only half-perceptable (warbly audio, mild shadows / reflections from people walking near the camera), so I would just feel like something was wrong but couldn't immediately place it.
There’s also the matter of familiarity — if you’ve already heard a song on good gear many times, your brain will fill in the gaps even on bad playback equipment, but finding new stuff might not be as enjoyable because much will be left out, like bass textures, interesting things happening with sound staging, and even entire bits of melody or background that aren’t easy to pick out with smartphone / laptop / normal car speakers.
Edit: the car case is particularly funny as many luxury brands offer $$$$-$$$$$ options for better sound systems when they can’t solve the fundamental flaws of compromised placement and background noise inherent to cars. That McIntosh system in your new $120k Jeep Grand Wagoneer might impress the neighbor but it still won’t do much to quiet the roar of real all-terrain tires on the highway.
