EF Sound Speaker

I love to listen to music wherever I go, whenever I want to and this unit makes that possible. It has a battery that offers a ton of music playtime, though I would say a bit less than the 25 hours of time that is stated in the description of the item itself. I find that the volume works well in all levels high, medium, and low without any distortion at all. It delivers on the bass sound as advertised in a major way. The construction of this speaker is awesome and very sturdy giving it the ability to survive a long time and many uses. It is very easy to travel with due to the handle that has been provided by the seller. I found that this speaker worker any device from android to IOS without issue. The Efsound speaker has a very strong signal and great sound which leads me to the highest recommendation I can give a device. The fact that I received this product free of charge or at a discounted rate had no influence on my thoughts regarding this product.
