"  The Sony SRS-XB3 offers great sound and a powerful bass from a small package. If you want even more volume, it can be paired with another SRS-XB3 to build a great party sound system. It is water-resistant, with a rating of IPX5. The downside is that Sony did not build any playback controls into the speaker so you will have to use your phone to play, pause and change tracks.    How We Tested: Our engineers in the Consumer Electronics and Engineering Lab evaluated wireless portable speakers based on ease of use, durability and performance. The lab tested each speaker for how easy it was to setup, connect to a smartphone and control music playback. The physical footprint and weight of each speaker was measured in order to factor in its portability. The sound level, sound quality and battery life were all assessed to evaluate the performance. Speakers that claimed to be waterproof or weatherproof were tested for these claims, and outdoor speakers were dropped multiple times to make sure they still functioned.
