What customers say about "Key Specs"
JBL Flip 4 Waterproof Portable Bluetooth Speaker
  • The battery life is amazing and I believe it does indeed last for the time stated here, if not longer.
  • It is robust, has a great sound, and the battery life is pretty good too.
  • The battery life is good, I've only once used it from full charge to empty and it almost lasted the 12 hours stated.
  • Battery life 12-15 hours. We have it sailing but haven’t had to test its water resistance yet! Sound is excellent and I can walk round the house and down both ends of the garden without losing it
  • The battery life is shockingly bad. A full charge lasts about two hours when streaming music from my phone...
Ultimate Ears BOOM 2 Wireless Mobile Bluetooth Speaker
  • I use it on my computer, when I camp, when I go literally anywhere. Even with constant use I’ve got about two to three days use.
  • The audio quality is great, it gets nice and loud, never have any issues with a seamless bluetooth connection, and I really like the graphic design of the speaker grille.
  • The best feature about this speaker is the endless battery life. It seems like I almost never charge it and it has 100 ft Bluetooth connectivity.
  • The product itself is great, but there are some firmware bugs. For example, it cannot connect to two devices simultaneously as advertised.
  • It will disconnect one device to connect to another one. Also, the tap control to pause and skip songs is not the best.

What customers say about "Features"
JBL Flip 4 Waterproof Portable Bluetooth Speaker
  • Excellent sound quality, love that it's waterproof and battery lasts ages.
  • The sound quality is fantastic for a speaker of its size. I've dropped mine several times and not a scratch and so far totally waterproof. A great buy.
  • Truly waterproof (tried and tested). Definitely a product worth what it is.
  • Have used it while power boating, kayaking and around the pool. Good waterproofing.
  • No problems at all with it. ipx7 waterproof is very good tried it every thing works perfectly.
Ultimate Ears BOOM 2 Wireless Mobile Bluetooth Speaker
  • However, the 360 sound is great, and it is really loud. Even at low volume the sound is clear and the bass is strong.
  • Very impressed with the amount of sound that comes from this speaker.
  • It also is Alexa compatible. Apparently, it is supposed to work with Siri and Google Assistant but I haven't figured out how to make either of those work yet. Very happy with this speaker.
  • I've had it plugged into the wall, playing music and the UE Boom app on my phone shows the battery is charging. I really like that I can turn the speaker on and off remotely with the app.
  • I just hope they update the firmware soon and maybe add actual buttons instead of unreliable tap controls.

What customers say about "Interfaces"
JBL Flip 4 Waterproof Portable Bluetooth Speaker
  • The charging cycle doesn’t last long and the speaker comes with a nice USB cable for charging.
  • A big plus is that it doesn't have the additional weight/headache of batteries as it's usb chargeable!
  • Connection via USB works without problems, the battery saves a charge for a long time.
  • I wish the charger came with a plug in for a wall and not just the USB cable.
  • The micro usb connector is just too weak or doesn't give enough support and ends up breaking on the unit.
Ultimate Ears BOOM 2 Wireless Mobile Bluetooth Speaker
  • Third one and I love it this is an amazing product that can handle any situation. Highly recommending these.
  • Overall very impressed by how easy the functions are, the quality of the sound, the size of the speaker, and the design.
  • Great interface is very simple and beautiful. There is nothing superfluous.
  • It's a shame that it can not be used as powerbank. This function would be needed.
  • Usb connector broke after a month of use. Charging may fall from the connector.
