Is the Anker Soundcore 2 Bluetooth speaker worth it?

Here's the part worth understanding before you buy one. IPX7 doesn't just mean splash resistant, it means the speaker can be fully dunked in about a meter of water and still work, which is a different, much more useful promise than the wipe-it-off rating on cheaper speakers. That's what actually lets it sit at the edge of a pool or get rained on at a campsite without anyone panicking. The bass side works on a similar cause-and-effect logic: a speaker this size physically can't move enough air to produce deep low end on its own, so Anker's BassUp technology uses a processor to boost those low frequencies electronically, then pushes the reinforced air through a spiral-shaped port that's tuned to carry it without buzzing or distorting. That's the whole trick, software correcting for what the size of the driver can't do alone. The battery works the same way, not a bigger battery so much as smarter power management stretched across a 5,200mAh cell, which is why it can run close to a full day instead of the three or four hours smaller speakers manage.
