Customer Ratings & Reviews

Got this speaker for my daughter in college and she uses it all the time. She likes how it’s so portable and has great sound.

It's got a lot of bass for the price and the battery does last a good amount. Its definitely worth $50 that I bought it for.

My kids have used various other speakers over the past 2 years. This speaker appears to be much clearer and have better volume.

Its loud and the bass is crisp. good enough for a automotive shop keep it plugged in as the charge for it sucks. Hour or two max fully charged

I love the size and the quality of this little speaker. You can use it for music and a telephone amplifier.

The SRS-XB21 is a big sounding speaker for the price. It may actually be a little TOO bass-y. But the sound is especially good for music.

My daughter loves her speaker. The sound is great and the size perfect for her to carry wherever she wants to listen.

Excellent sound quality. Very loud, so teens would love it. Charges quickly. Only negative is the very short charging cable.

I love this speaker. The sound comes out amazing specially for music with a lot of bass. The sound can get very loud as well.

Great speaker option if you are looking for portability and sound quality. It is small (easily fits in your hand) but mighty. It is nicely designed and seems heavy for its size but I think that speaks to good construction and speaker magnets. It sits on 4 nice little rubber “legs”. In typical Sony fashion there are buttons on the top of the speaker that you can use to control an attached device (such as moving forward/back thru your playlist), pause/play. To do some functions you have to know the "combination" to use (multiple taps on certain buttons You can download Sony’s app for added control. With it you have access to a lot of different settings/functions such as bass/mid/treble, light affect, chaining other Sony speakers, etc. As such you should be able to tune the speaker to your particular preferences/sound. A unique speaker feature is – depending on where you tap it – a sound affect will play. You can set the sound you want such as percussion or drum kit, etc. Could be fun at a party I think. On the back there is a "port cover" under which you will find a USB attachment you can use to keep your device charged. An external input using I believe 3.5 mm (1/8 inch) jack - so you could use your old non-bluetooth devices - I used it with an old ipod and it worked fine. There is also the plug to charge the device as well as buttons to turn light on/off, VPC and to add a speaker to “chain”. Speaker has a nice battery voice feature. If you press the battery button within the back port it states how much battery charge you have. As far as charging – make sure you are use 1.5A to get it done ASAP (rather than 500mA). The only “negative” I have is since our speaker is black and the control pad is black – it was a little hard to see/navigate. But we have old eyes! Oh and it could have google or amazon built in… I would definitely recommend this speaker. It is water resistant, VERY portable, and certainly loud when both speaker and device are turned up full blast. It is supposed to play 12 hours on a charge (I only tried 8 hours and it was still going strong).

This was a house warming gift my sister-in-law, She loved the quality of the sound ease of use to her IPhone and MAC Air

Really like the great sound with plenty of bass, even at low volume, such as an office environment. Easy to sync and play.

Wonderful speaker at low cost with superb sound and Very nice to handle. Could possibly use at any place. easy to handle.

Bought this blue tooth speaker for my boyfriend and he loves it. Sounds good. Good clarity. Easy connection and portable.

the sound is good, same as bass the battery is not the best probably the flashing lights dry it fast but in general works fine

Really provides great quality sound for such a small speaker. It really is easy to transport and not too heavy.

We use our speaker in the golf cart, by the pool, and on the porch. We love the quality of the sound and the size is perfect.

This is a great speaker -good tone and like the rotating lights that move with the music. Easy to set up and use.

The speaker was easy to set up and pair with other devices. Good range. Good sound quality. A good buy for the price.

Just what I needed for the summer. Easy to take with you on trips or use for a bonfire. Good quality, Bluetooth capable.
