“a Flip 6 should be louder than 2 xb100, even though the sound quality at those high volumes is not the best. At moderate volumes, the Fllip 6 has stronger bass and is more crisp/more detailed.”
“The fabric starts to get loose overtime & if condensation builds inside could cause a short, it's really hit or miss on build quality with some ppl never having any issues & others having loose fabric after one shower”
“Overall I prefer the sound of the Bose and the overall better bass preformance. But on certain songs the flip 6 does have noticeably better clarity and I’d say it’s because the speaker has a tweeter.”
“The JBL Flip 6 is a solid update to the JBL Flip 5, and the IP67 rating is a welcome upgrade. It's rugged and durable and won't take up much room in your bag for that weekend getaway or trip to the beach.”
“The battery dies even when plugged in and suddenly the noise stops playing and the speaker turns off, leaving only the blinking white light.”
“Grip is warmer, also because it doesn't have a tweeter. But you can reduce treble on the flip 6 as well. It is more powerful than the grip.”
