  • Love this speaker
Color: White Style: Black Handle
Love this speaker. Great sound

  • 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

  • LOUD
Color: Tan Style: Black Handle
I have one normal turtle box, got this one for tailgating and larger gatherings, and man does this thing bump. Easily twice as loud as my original. When paired together the original is essentially drowned out unless you put them far apart. Will be buying another one for stereo

  • 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.

  • Awesome
Color: Gray Style: Black Handle
LOUD. It is awesome. Don’t sleep on the Turtleboxes. Have all three sizes and they are all great

  • Microphone did not work well
Color: Tan Style: Black Handle
Don’t really see what all the hype is about. I bought the grande to sync with the other speakers I have because I guess that’s the only way to sync with a microphone. The sound lags. It did not sound good. And it’s too heavy and too big…
