Older models: the Sony XB33 (ranked lower, rated 3.4/5), the Sony SRS-XE300 (ranked lower, rated 2.8/5), the Sony SRS-XB31 (ranked lower, rated 2.8/5) and the Sony SRS-XB30 (ranked lower, rated 2.6/5). See every Sony XB and ULT generation.

Same family: the Sony ULT Field 1 (smaller model, ranked lower, rated 3.1/5), the Sony ULT Field 7 (smaller model, rated 3.2/5), the Sony ULT Tower 10 (smaller model, rated 3.9/5), the Sony ULT Field 5 (larger model, rated 3.5/5), the Sony ULT Tower 5 (larger model, rated 4.5/5), the Sony ULT Tower 7 (larger model, rated 4.7/5), the Sony ULT Tower 9 (larger model, rated 4.2/5) and the Sony ULT Tower Max (larger model, rated 4.8/5).

Pros: A rugged waterproof stereo speaker with long battery life, a detailed app EQ, a shoulder strap and a phone charging port. A 1.2 kg IP67 stereo portable with a 24-hour battery, a 10-band app EQ and a USB-C output for charging your phone. It is dustproof and water resistant, Party Connect links up to 100 speakers, and a detachable shoulder strap is included.

Cons: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together: turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
