THE VERDICT

SRS-XB100 is the stronger buy for most people because it combines the broader spec lead with a more defensible price. Wonderboom 4 is not a bad pick, but it only makes more sense if its narrower strengths line up exactly with your workload.

Buy SRS-XB100 if you want the safest all-round choice in this price tier.
Pick Wonderboom 4 only when one of its standout strengths matters more than balanced value.
Do not compare these two in isolation; keep your actual budget ceiling in view.
