Ultimate Ears BOOM 3 vs JBL Flip 6

The Ultimate Ears BOOM 3 is a slightly better speaker than the JBL Flip 6. The Ultimate Ears has a fantastic immersive, open-sounding soundstage. It gets as loud as the JBL with less compression at max volume, resulting in cleaner audio at louder volume levels. It also has a longer-lasting battery life making it better suited for long listening sessions. However, the JBL offers a better-balanced sound profile out-of-the-box and can produce a more extended low bass. It's a bit smaller in size, and you can pair it to up to two devices at a time, so you can easily switch between audio sources.
