Both of our G-GRIP and G-TUBE portable Bluetooth speakers sound great. Both are rugged and are designed to stand up to your daily grind while on the go.
G-TUBE is the newer design of the two. It has dual 1.25” speaker drivers and is IPX5-rated water resistance, has a built-in rechargeable battery for up to six hours of play time. It also features a headphone jack so you can plug your headphones into G-TUBE’s headphone jack to stream music wirelessly while keeping your phone safe in your bag or backpack.
G-GRIP has a built-in rechargeable battery for up to eight hours of play time. It has dual 1.5” drivers with Neodymium magnets and a rear firing passive radiator. G-GRIP is a super tough portable speaker that in lab tests withstood drops of over 8 feet and a crush force of over 1,339 pounds - heres a link showing us run it over with our VW Jetta Wagon: https://www.youtube.com/watch?v=rw8_IIvR0kE
