    • Worth it
Color: Tan Style: Black Handle
Got the Turtlebox Grande Speaker for the boat and it’s exactly what I wanted. Loud enough to hear over wind and water no problem, and it still sounds clean. Perfect for sandbars, river days, or just pulling up somewhere and turning heads. Battery lasts all day and it’s built to take a beating.

    • Lives up to its reputation.
Color: Gray Style: Black Handle
Bought this for my fiancé for Christmas. It lives up to its reputation for sound quality and durability. We take on our boat in the bayous, canals, and Atchafalaya. Nice to not have to worry about moisture. But what I love most, is the sound quality. It has amazing richness and depth. ♥️

    • Good sound quality
Color: Tan Style: Black Handle
Not as much bass as I would like but it still sounds really good and really clear. The range is also one of the reasons I bought this. You ca walk away from it pretty far and it doesn’t loose connection with your phone.

    • Deep Bass, Clear Sound, Built for Loud Environments
Color: Tan Style: Black Handle
Use: Outdoor Softball walk up and in game music. Reason for Purchase: To upgrade lower performing portable system. Previous System: JBL PartyBox On-The-Go / 100W / Bluetooth New System: Turtlebox Grande Huge upgrade from my JBL PartyBox On-The-Go (100W Bluetooth). The TurtleBox Grande delivers clearer vocals, stronger highs, and noticeably deeper bass without distortion. Where it really shines is outdoors — it easily cuts through the noise at busy youth softball complexes with multiple games and speakers competing for attention. If you need powerful, reliable sound in loud environments, this speaker is worth every penny. ... show more

    • Great sounding speaker Poor Packaging
Color: Tan Style: Black Handle
The Turtle Box Grande is awesome but for the price I paid for it I would have hoped the packaging would have been better. When I open the Amazon box to get the turtle box out the box was in pieces leaving the unit exposed. Not sure if it is a used unit or not.
