Review on Sony SRS-XB12 Mini Bluetooth Speaker with Extra Bass - Portable Wireless Speaker for Phone Calls - Waterproof and Dustproof Travel Music Speaker - Black (SRS-XB12/B) by Jose Ortega

Tiny speaker that sounds great considering its small size. Loud in the room. Haven't tried it outdoors yet so I don't know how it is. Connecting via Bluetooth is easy. Battery life is good. The bass is good for its size. Of course this is a small speaker so I don't expect it to sound like a party. I'm not a bassist. Heavy bass sometimes annoys me, so I was afraid of "extra bass" which I almost never bought. The good thing is that the bass isn't overwhelming, just the right amount and for my taste. Clarity is good enough for me. If you're not an audiophile, forget the bad reviews because the truth is the sound isn't terrible at all. If you try songs with high quality, you will appreciate it more. The only thing I don't like is that there is no way to disable Bluetooth. Please note that when the battery is low, the volume will automatically decrease even if it is maximum, so please charge it first. I noticed that the negative "low volume/not loud enough" reviews are from people who just opened the box. This speaker is definitely loud for its small size.
