Review: Me gustó mucho, es sencilla de utilizar, sonido aceptable para la fiesta, no esperes sonido Hi end.
Review: I have used a JBL Flip 5 for a few years and am still happy with it. I wanted another bluetooth speaker to use in my workshop. The sound samples from Flip 6 were good in the bass but sounded too hot in the treble for me. The Wonderboom 4 also sounds like the high end has too much sizzle for my taste. The Flip 7 sounds a lot better but is $50 more expensive than the current Boom 4 at $139 CAD. Note: The Boom 4 price has moved back up to $199. Flip 7 might be the better deal at this price point. Boom 4 seems to really shine in the clear and dynamic presentation of a natural midrange. The Boom 4 low end rolls off a bit more than the Flip 5 but retains a punchy presence. The Boom 4 really outshines the Flip 5 in its clarity and dynamics. This little speaker seems very well suited for my listening tastes of classical, jazz and other laid back styles. The UE app has battery indicator, a nice remote power on feature and a simplified EQ adjustment. It can also control playlists from Apple and apparently some others. This speaker will please people with similar tastes but probably not satisfy younger beach party listeners whose contemporary playlists appreciate the boosted bass and treble frequencies of other designs.

*by C***S on 9 January 2026*

Enjoy using this speaker with my tablet. It allows me to walk away, even into another room, without carrying the tablet or even the phone and still listen. Just turn up the volume and you're hands free. If I go a greater distance into the kitchen I'll carry the speaker there. It will start fading in and out when I've gotten too far from the tablet or phone and I just reposition it. It's nice to hear music in the car because the quality is better than the phone when I connect the speaker to it. Very convenient and very portable.....gives a greater listening distance to what it's connected to and the audio is an improvement from the devices' speaker with nicer tones. Really like the convenience of it. Used it during the holidays. Connected it to my phone and played dinner music....guests enjoyed it and were curious how it worked. It uses a simple Bluetooth connection to pair. There is an UE Boom App that can be downloaded that will help with pairing also, if needed. I enjoy that I can move around or drive and don't need to have something in my ears to listen and it's light enough to move and sit on a table or the seat of the car. I haven't tested how water proof it is but I did spill some water on it and just wiped it off with no problems. Durable speaker and the sound is deeper and richer for something so portable. Hope you enjoy the speaker if you decide on one.
