Portable wireless speakers are so common today. They come in a huge range of sizes and styles, and with a variety of features. Sony has been at the forefront of this market, and has numerous portable Bluetooth speakers. I’ve reviewed many Sony products, including previous incarnations of Sony’s SRS-XB or EXTRA BASS speaker line.

All about Sony SRS-XB21, SRS-XB31 and SRS-XB41

New this season at Best Buy is another trio of speakers under the SRS-XB line: the compact SRS-XB21, the mid-sized SRS-XB31 and the full sized SRS-XB41. This review will take a look at each of the speakers, their differences, and how they sound.

Common features in SRS-XB lineup

Though there are some differences between each speaker, they do each have some common features.

What is Sony Extra Bass?

Sony’s Extra Bass technology is the key feature of these speakers; it’s what they’re named for, and what the “XB” in the name stands for.

EXTRA BASS technology essentially lets you get more bass out of your music. The Sony EXTRA BASS headphones and speakers use what’s called an Electro Bass Booster to make the lower tones of bass lines more prominent. This battery-powered enhancer digitally increases low-frequencies in the music and maximizes the deep, punchy sound and rhythmic feel. The feature can be turned on or off to suit your mood.


How to use Sony Party Booster?

Party Booster is available with SRS-XB41, SRS-XB31, SRS-XB21 and when it’s enabled, the speaker will make sound effects when you smack it; “makes the party atmosphere more exciting,” according to Sony.

There are several kinds of sound effects, which can be enabled or switched with the “Sony Music Center” app, or you can hold the volume up and down buttons simultaneously to turn this feature on and off.
