Sony Extra Bass Wireless Speakers: SRS-XB23 vs. SRS-XB33 vs. SRS-XB43

Sony recently released three extra bass wireless speakers with the SRS-XB23, SRS-XB33 and SRS-XB43. So which of these best fit your needs? You can find out in this comparison guide between the three products.

Quick Summary

The Sony SRS-XB43 Extra Bass Wireless Speaker is the best option out of the three as it comes with a built-in tweeter (for clearer vocal audio), Live Sound Mode (for 3D audio effects), lighting effects in addition to support for Fiesta App and NFC. The only disadvantage the SRS-XB43 has over the other two speakers is that it is more vulnerable to being damaged from bumps and drops.

Aside from not having a tweeter, the Sony SRS-XB33 Extra Bass Wireless Speaker is nearly identical to the SRS-XB43. If you don’t care about the benefits of a built-in tweeter, then you might want to get the SRS-XB33 instead as it is more affordable.

Although the Sony SRS-XB23 Extra Bass Wireless Speaker don’t have as many features as the SRS-XB33 and SRS-XB43, it is the most affordable option of the group.
