    • The Sony SRS-XB31 portable wireless Bluetooth speaker is great
    • Mind you, I've had quite a few bluetooth speakers that have been smaller than this, less expensive, and have better sound.
    • First of all....I LOVE THIIS portable wireless Bluetooth speaker by SONY
    • It is probably the loudest bluetooth speaker I have had my hands on in the year

    Sony SRS-XB21 Portable Wireless Bluetooth Speaker, Blue (SRSXB21/Ll)

    • The sound is very good and the battery life is excellent.
    • This Speakers has big but detailed sound as well as an excellent battery life
    • This is a great speaker, very good sound, very good battery life
    • One issue I did have and found that other people have, though, is that it will stutter as if it’s buffering about once per song when connected to an Android phone running 6.0 Marshmallow, which admittedly is a few years old now
    • Took this on a float trip and the battery life is very good

    Sony SRS-XB21 Portable Wireless Bluetooth Speaker, Blue (SRSXB21/Ll)

    • It is a well built sturdy Sony product however and that's why I gave it three stars
    • I usually don't like products that also have an app, because the app is usually crap, but not so with this one
    • I love Sony products so I am a big fan and expected a lot from this speaker
    • When this Sony popped up in my Amazon Vine queue for products available for sampling and review, I almost passed on it since I already have all I need in small BT speakers, but the synced lighting effects on the face of the unit looked kind of fun to me (besides affording my wife the opportunity to roll her eyes at me saying, "Really
    • Awesome sound though with nice bass; an overall great little product.

    • However, I expect longer life now that I have seen all the lighting modes I need to see and have disabled the lighting
    • This is a nice speaker with amazing bass sounds and cool lights
    • Great bass and the lights are pretty cool when you have them going
    • Programmable LED lights (that syncs with the music)- Water
    • Hopefully they'll update the app to let you totally disable the strobe lights (like, really, they're an actual health issue for some people)

    Sony SRS-XB21 Portable Wireless Bluetooth Speaker, Blue (SRSXB21/Ll)

    • It's hard to find a good speaker these days without forking over hundreds - this is a great speaker at a really good price point.
    • Best buy wanted 100 bucks for the same speaker so this is an awesome price.
    • The sound is great and loud for such a small speaker and reasonably priced speaker
    • Sony has managed to get everything right with this portable wireless Bluetooth speaker and managed to get the price fairly reasonable as well
    • It is either defective, or the quality of this speaker is definitely NOT worth the hefty price tag

    • but if you disable it the sound quality becomes quite good
    • Sound quality is really good, easily rivaling that of our gen 1 Echo and UE Boom.
    • The sound quality is very good with excellent bass for such a small speaker
    • This is by far the best sound quality I've had from any Bluetooth speaker
    • Exemplary build quality- Water, rust and dust/dirt proof (

    Sony SRS-XB21 Portable Wireless Bluetooth Speaker, Blue (SRSXB21/Ll)

    • I got to thinking, in order to be fair and give Sony the benefit of the doubt, I had failed to consider in my first test run and review, that the short battery life might have been the victim of running the "light show" on the speaker, the whole time that it was playing loud music
    • so you get additional sounds out of while your favorite music is playing
    • It's lazy, and it ruins anything but a subset of popular music with no complexity to lose in the first place
    • It's lazy, and it ruins anything but a subset of popular music with no complexity to lose in the first place
    • If the music is even moderately loud, the tapping and hitting registers enough to trip the lights, but the playing of the music apparently overrides the party booster action.

    Sony SRS-XB21 Portable Wireless Bluetooth Speaker, Blue (SRSXB21/Ll)

    • (Sony XB10 Portable Wireless Speaker with Bluetooth, Black) speakers and assumed these would be like those but bigger and better
    • The only other experience I've had with Sony wireless speakers is with the Sony XB40 Portable Wireless Speaker with Bluetooth and Speaker Lights, Black, and that was very positive
    • Sony doesn't disappoint with this small portable Bluetooth speaker
    • Sony also reduced the number of controls on the top of the device, which is okay, since you are able to access all of the options via the Sony Music app
    • The speaker is loud, and maybe the Bose sounds better (sound link, sound revolve, etc, but they dont't sound as loud as the Sony, in my opinion I wanted to buy the best speaker there was an jbl that cost 450$ but it was to big, Sony is the best portable speaker period I checked all speakers in the store

    Sony SRS-XB21 Portable Wireless Bluetooth Speaker, Blue (SRSXB21/Ll)

    • These small Bluetooth speakers purposely overemphasize bass and trick the ear into being impressed
    • The sound profile was lacking bass and lacking good human singing voice reproduction, the sound's dimension felt small and narrow, and did not hold up in high volume
    • The mids and high come through convincingly and the bass is loud without being too boomy or clipped.
    • The sound quality is very good with excellent bass for such a small speaker
    • Not only is it great looking, it also has good bass and other cool features

    • Not only is it great looking, it also has good bass and other cool features
    • LOL.The multi-directional feature is cool, and works great for a small speaker like this.
    • I was really surprised how much I like the light feature
    • LOL.The multi-directional feature is cool, and works great for a small speaker like this.
    • If you pour water on your speaker you don't have to worry as it will bead off the thing.

    Sony SRS-XB21 Portable Wireless Bluetooth Speaker, Blue (SRSXB21/Ll)

    • I also got a hard case that fits perfectly (Esimen 2018 Design Hard Case
    • The color changing LED’s are really fun and give a cool ambiance to any party scene.
    • One issue I did have and found that other people have, though, is that it will stutter as if it’s buffering about once per song when connected to an Android phone running 6.0 Marshmallow, which admittedly is a few years old now
    • We use it for background music at home as well as when my daughters are practicing routines with their music.
    • Usually, I would recommend this option; however, the flat line on the EQ did sound as good as if you elevated each of the three areas (treble, midtone, bass) in some successive pattern

    • Where it loses stars is the power cord and battery life

    Sony SRS-XB21 Portable Wireless Bluetooth Speaker, Blue (SRSXB21/Ll)

    • The music app is a bit difficult for me at first, yet it all depended on if I had enabled Bluetooth, and registering this baby was not allowed at one point,
    • While the flashing lights are great for when I have guests, personally I enjoy the lights when I'm home alone too because I just love a bit of a light show any old time
    • The light system, while gimmicky, adds a bit of fun, as does the ability to setup multiple speakers in a group
    • It's always a bit difficult to review a non-book item as I never know how long it will last
    • The IP67 rating and the other features mentioned make it a decent option that will provide some durability that's missing from many other portables, but the bass response and lack of charger detract a bit.
