I have been using Sony portable wireless Bluetooth speakers since SRS-X3 came out and love both the quality of the hardware and the sound.

It is probably the loudest bluetooth speaker I have had my hands on in the year

Sony doesn't disappoint with this small portable Bluetooth speaker

For the price, this is a good wireless bluetooth speaker to use outdoors by the pool, on the go, or in the classroom.

This is one of the best Bluetooth

The Sony app easily works with my iPhone and allows for easy Bluetooth connection, changing audio settings, and connecting both to my Songs and TuneIn apps

Set up was a “breeze,” Bluetooth is strong and available on all the devices tried; iPhone, iPad and Mac Air.

Portable Wireless Bluetooth Speaker puts out

I've tried so many Bluetooth speakers, inexpensive and not, that my expectations for this Sony were low, so I was pleasantly surprised when the sound quality and construction proved to be exceptional for a speaker of this size.

The Sony SRS-XB31 portable wireless Bluetooth speaker is great

This is far and away the best bluetooth speaker that I own--and I own many (though admittedly, this is also the most expensive)

I have a competing bluetooth speaker, the Anker Soundcore 2 Portable Bluetooth Speaker with Superior Stereo Sound, Exclusive BassUp, 12-Watts

This portable Bluetooth speaker arrived well-packaged with a simple start up instruction sheet and other information.

The bass left a little to be desired, but I have to say that it is the best I have ever heard from one of these little portable Bluetooth speakers

Mind you, I've had quite a few bluetooth speakers that have been smaller than this, less expensive, and have better sound.

Very nice Bluetooth speaker with colored lights which flash according to the music

The Sony SRS-XB21 is an attractive bluetooth (BT) speaker that has many 'extras' that other speakers this size do not -- including NFC pairing, 'party lights', and the ability to 'chain' several speakers together

Still, this is the best portable Bluetooth speaker in its size that I have ever used
