Review on Sony SRS-XB33 EXTRA BASS Wireless Portable Speaker – IP67 Waterproof, Bluetooth, 24-Hour Battery, Built-In Mic for Phone Calls (Red) by Todd Wigfall

The sound quality of this speaker is good and the blinking lights feel nice. However, it's not nearly loud enough for my purpose. At full volume with my phone set to maximum, the speaker just fills the 12x10 interior. As it is intended to be used in PWC where it needs to overcome engine noise I'm not sure it will be loud enough. I suspected this would happen when Sony refused to discuss specs like SPL or performance and compare them to the competition. Unfortunately I have waited over a week for delivery due to Revain having stock issues on this new device. Also, the NFC function didn't work with my Samsung phone. It's ok as pairing via BT is quite easy. Now that Sony is overselling the XB33's capabilities, Revain gets a good product back and pays shipping both ways, but that's the beauty of the Prime.
