Loud and Clear!
Color: Gray Style: Black Handle
Excellent Speaker. Arrived on time. Music is loud and clear. Battery lasts a long time in between charges (all day). Very sturdy. Glad we got the larger one. We also have the smaller one and it’s great for floating and outdoor activities and we have no complaints about the smaller one. However, there’s zero comparison between this one and the other. ... show more

Very good, not great
Color: Gray Style: Black Handle
Just received this speaker and testing it out, once you adjust the equalizer on your phone it sounds pretty good for what it is. Past 80% volume its not so great, loud yes, but sound quality drops. Majority of the time i wont have it up that loud. Was delivered quickly, and packaging was great. Actually pretty light weight for a 10" sub. Im on the fence with this speaker, for this price I think the JBL is a better choice. Debating on keeping it or send it back and get a JBL ... show more

Great sound!!!
Color: Gray Style: Black Handle
This speaker blows away all others. The sound is great and the waterproof feature is great for the rainy days at the softball field. Battery life is amazing and last about 3-4 days using it for walk up songs plus warmups. Yes it’s expensive but Ive wasted more money on speakers trying to find one that will produce like this one. Make sure you have your Bluetooth setting on speaker to get the max sound out of it. ... show more

Blown away good. Very loud, very clear, well balanced albeit a bit bass heavy. Battery life is awesome. It's damn heavy. Paired with a Audio2000s tripod, you have a good looking set, and keep the sound band at ear level.
