Our Verdict

Sony SRS-XB33

Sony SRS-XB43

The Sony SRS-XB43 is better for most uses than the Sony SRS-XB33. Though both speakers have an uneven sound profile out-of-the-box, the XB43's are better balanced. It can also get louder. While the XB33 lists an IK rating for impact resistance, there isn't an IK rating specified for the XB43. Also, the XB33 has lower latency via Bluetooth with Android and iOS devices, though some apps compensate for latency, so your experience may vary.
