The speaker features Sony’s signature EXTRA BASS for deep, thumping lows, paired with Live Sound Mode that creates a 3D immersive experience mimicking live concerts.

At $69, this older model offers flagship-level features at a fraction of newer prices, making it a smart buy for value hunters searching for the best portable Bluetooth speaker under $100.
Pros
The Sony SRS-XB31 shines in several areas, earning its high ratings from users who prioritize fun, power, and reliability. Here are the top advantages:
- Immersive Sound with EXTRA BASS and Live Sound Mode: Delivers punchy bass and 3D audio that fills large rooms or outdoor spaces. Users rave about its performance on EDM, hip-hop, and R&B, outperforming competitors like JBL Charge 3 in party scenarios.
- Exceptional Battery Life: Up to 24 hours of playtime keeps the music going all day and night, ideal for extended events without frequent recharges.
- IP67 Waterproof and Dustproof Design: Worry-free use at beaches, pools, or dusty environments. Splashes wipe right off, and it survives submersion.
- Party Features with Lights and Party Chain: Multicolored lights and strobe sync to the music, creating a vibrant atmosphere. Link up to 100 speakers for epic setups.
- Portable and Lightweight Build: Easy to carry despite its powerful output, with a premium fabric cover and solid heft that feels durable.
- Stereo Pairing Capability: Add another unit for rich stereo sound, enhancing the listening experience without wires.
- Outstanding Value at $69: Premium features at a budget price, especially as an older model—saves money compared to newer iterations.
Cons
No speaker is perfect, and the SRS-XB31 has a few drawbacks noted by some users. While minor for most, they’re worth considering for balanced decision-making:
- Battery Degradation Over Time: Several owners report charging issues after prolonged use (e.g., 1-2 years), with batteries failing to hold charge reliably. This seems like a common wear-and-tear issue.
- Bass-Heavy Sound Profile: Excels at party genres but may lack balance for classical or vocal-focused music, coming across as boomy for audiophiles seeking neutrality.
- App Dependency for Full Features: Lights, EQ, and advanced settings require the Sony Music Center app, which works well but adds a step not needed on simpler speakers.
- Initial Pairing Hiccups: Stereo linking with another speaker can take time, frustrating users expecting instant setup.
- No Built-in Power Bank: While durable and long-lasting, it lacks a USB output for charging devices, unlike some rivals like JBL models.
Customer Reviews Analysis
With a 4.6-star average from 1,099 reviews, the Sony SRS-XB31 garners widespread praise, but a closer look reveals nuances. Positive feedback dominates, focusing on sound quality and fun factor.
Positive Highlights
Five-star reviewers call it an “epic mid-sized all-in-one speaker,” highlighting its light show, durability, and stereo drivers spaced for wide soundstages. One user, a JBL fan, declared it their new favorite over the Charge 3, loving the Live Sound Mode for EDM and hip-hop: “Awesome large room-filling sound while managing to keep bass present is excellent for a speaker this size!” The app integration on Android devices like the Galaxy S8 gets thumbs up for customizing lights and EQ.
Build quality impresses, with the fabric cover and heavy feel earning “expensive” vibes. Water resistance holds up to splashes, and battery life matches claims. Stereo pairing delivers “great stereo sound,” and at $69, many are thrilled they skipped newer models: “For the price, I am glad I bought this older model.”
Negative Highlights
Lower-rated reviews (including some 0-1 star outliers) point to reliability concerns. One buyer purchased a second unit after the first developed charging problems: “Sound quality and bass was great… but the second seemed to have the same exact problem.” Longevity is a pain point after “a few years combined.”
Some note the sound’s party bias: “Not heavy bass, not a tinny sound—best all round,” but others imply it’s tailored to bass-heavy genres. Pairing delays for multi-speaker setups frustrate, though most resolve. Overall, 80-90% of feedback is positive, with negatives clustered around battery life post-warranty.
In summary, if you prioritize immediate performance and value, it’s a hit. Long-term users advise gentle handling to maximize lifespan.
