Wi-Fi is better for music since these connections have much higher bandwidth than Bluetooth, meaning your music isn’t additionally compressed, making for higher-quality audio. Bluetooth can still sound good and is very useful (and is probably good enough), but for lossless or hi-res audio, Wi-Fi is your only option.
Bluetooth may not offer the highest-quality audio, but the good news is in many cases, this doesn’t matter much. If you’re doing most of your listening via Spotify, a higher bandwidth connection isn’t going to offer any sort of upgrade anyway (since Spotify doesn’t have the best audio quality).
Some streaming services like Tidal, Deezer, Apple Music, and Amazon Music Unlimited offer either lossless audio, hi-res audio, or both. With these, you may notice a slight upgrade in sound quality over Wi-Fi, but even that is debatable.

Bluetooth and Wi-Fi are two ways to wirelessly stream music from your devices to speakers, but which is the best option for you? While one definitely has higher-quality audio than the other, as you’ll see they’re both still worthwhile.
