What the Soundcore Boost “original model” pre-2021 offers: A great sounding neutral speaker. Watch for: This old version has micro-usb charging. Only IPX5.

Customizable EQ and speaker-pairing via the UE app. Watch for: Not much improvement over the old ones. Weak bass extension and thuddy bass. Gets distorted above 90%
