You can't easily get big sound out of a small object, and when a speaker is designed first and foremost to be tiny, you can be confident it won't rock the house. Sony's Bluetooth Wireless Mobile Speaker SRS-BTV5 is proof of that. This $69.99 (direct) speaker is a little larger than a pool ball and looks good, but it can't output loud music—or even close to it. It's a nice novelty speaker, but there are other Bluetooth speakers that are still portable at twice the size and sound much louder, such as the Editors' Choice Logitech UE Mobile Boombox($280.00 at Amazon). DesignThe speaker is a little black ball measuring 2.6 inches in diameter and standing 2.8 inches tall, making it only slightly larger than a pool ball. It weighs 4.8 ounces, and whether you toss it in your bag or hang it from the drawstring of the included mesh basket pouch you'd hardly notice it's there. It comes in black, white, and pink versions, all of which are otherwise identical. The single driver sits under the...

The Sony Bluetooth Wireless Mobile Speaker SRS-BTV5 is small, cleverly designed, and unfortunately low on power output.

Compact; Attractive; Easy to pair

Weak bass; Tinny treble; Speakerphone feature isn't very loud

Best little speaker to get and love the size

This small but mighty little speaker gives great clear sound at an astonishing volume for its size, it also has an excellent mic built in for taking calls and doubles up nicely as a hands free if you use a cradle for your phone in the car.

Small but powerful..,.you would be surprised!!!

Sony has a knack for coming up with products with great design. And weird names. The SRS-BTV5 wireless speaker has both of those qualities. A spherical wireless speaker of 6.5 cm x 6.76 cm x 6.5 cm dimensions, it is small and light enough (135 grammes) to slip into a trouser pocket and comes with...

Good sound, ultra portable, I take it everywhere with me, not only when I travel. Only issue perhaps is the battery life, which is like described, but longer would be better. However, it is not something that was not part of the specs, so I am ok with that.

Great sound for a little speaker. Only complaint is process needed to pair with bluetooth device. I would recommend this little beauty to friends.

It is a very small yet very powerful gadget. perfect for listening music alone/in a small party.

Connects Easily; Good Sound; Good Volume Control; Lightweight; Long Battery Life

Great design and build quality. The size makes it very portable, but it also limits the sound. The sound isn't very loud. If you want something that's portable, looks good and sounds better than your average phone or tablet this will be fine, but don't expect a drastic improvement.
