JBL Flip 4 Review

JBL Flip 4 Review
The JBL Flip 4 is a wireless Bluetooth speaker with an ultralong runtime and robust waterproofing that makes it the perfect portable sound system for any outdoor gathering. Features like JBL Connect+ compatibility and the ability to synch more than one phone or tablet also make it a highly social speaker as well, cementing it as a favorite for on-the-fly gatherings.


12-hour runtime

The JBL Flip 4 stands out in the world of wireless Bluetooth speakers thanks it its remarkably long play time. Thanks to its high-quality li-ion polymer rechargeable battery, the JBL Flip 4 boasts a max runtime of 12 hours. That means you can use it woo you to sleep at night or to keep the party going until the break of dawn—all on a single charge. Additionally, charge time is roughly only 3 hours, so it has a very solid charge time to runtime ratio, which isn’t always the case in the portable speaker world.

The Flip 4 can be connected wirelessly via Bluetooth to up to two mobile devices at once. This means you can have your iPhone and your iPad synched at the same time, or, conversely, you and a friend can synch both of your phones and to find out which one has the better play list. This is great for parties as well, because it allows you to double your song library to keep the party hopping.

JBL Connect+

Perhaps the coolest feature about the JBL Flip 4 is its JBL Connect+ compatibility. You can link more than 100 JBL Connect+ enabled speakers together, creating your own custom sound system. Once again, this is a social-friendly feature, because it enables parties on the fly. We all know one portable speaker can’t reach the ears of dozens of people, but when you link them together, multiple Flip 4s can create a rich sound to rival any standard-sized speaker system.


The JBL Flip 4 boasts an IPX7 waterproof rating. This means that its waterproofing features go way beyond simple spills and getting caught in a light rain. The Flip 4’s waterproofing is so robust you can actually submerge it in water, which makes it an ideal poolside companion that’s perfect for pool parties, BBQs and water sports events.


The Flip 4 has a built-in noise-cancelling microphone and with its ability to synch with your phone, you can use the Flip 4 to up your conference call game. You’ll be able to hear your colleagues loud and clear; likewise, your voice will come out crystal clear on their end as well. With this feature, you also get Voice Assistant Integration, which allows you to access Siri or Google Now directly via your Flip 4 speaker.

First impression
First impression of the JBL Flip 4 Bluetooth Speaker

I like the fact that the Flip 4 comes in different colors. We got each of the colors for various members of our household so we can easily know whose is whose. I mention this issue as a parent, because it means that the kids aren’t going to fight over a particular speaker. For instance, my daughter has the speaker in teal and my son has the speaker in red.

To me, by far the coolest thing is JBL Connect+; with Flip 4’s JBL Connect+ compatibility allows you to link multiple compatible devices, and we tested out this feature with our speakers. You really do get stereo sound with two linked speakers. With multiple speakers, you get volumes loud enough for a party.

I’m also a big fan of the waterproofing. We have a pool and have been looking for a decent quality waterproof speaker to listen to music poolside and the Flip 4 definitely fits the bill. Not only can you actually hear the speaker while you’re having fun in the water, it lives up to the submergible claim, which I tested with my own personal Flip 4. It sinks to the bottom, and it’d be nice if it floated, but once I retrieved it and set it by the side of the pool, it was still working flawlessly.

The 12-hour runtime lives up to the hype when you set it to a typical listening volume. Of course, that time is shortened when you crank up the volume, but not by much. It’s definitely got enough battery life in it to hold out through a house party or a pool party even at max volume, both of which are the primary reasons you’d probably have it turned up to the max for long periods. So, it definitely does the job there.

It’s also quite easy to synch up more than one phone via Bluetooth. My wife and I tested out this feature, and it was downright effortless. So, the Flip 4 definitely gets points for being user friendly on the Bluetooth synching front, and also for living up to the two devices claim.

Overall sound quality is quite good, but obviously it’s much better if you link together two speakers to create a stereo experience. Still, on its own, one speaker is definitely a very worthy portable listening device. The bass is pretty good and the mids, while the highs are free of distortion. It’s not going to wow audiophiles, but for general music fans who want a good portable speaker, you can’t beat the Flip 4’s audio quality.

  • The JBL Flip 4 isn’t designed to float. This isn’t a deal-breaking issue nor does it impact the function of the speaker as a whole, but since it’s waterproof, this would be a nice addition to have.
  • The runtime may be less than 12 hours if you have it up at max volume. This is true for any battery-powered speaker, however, due to the limitations of our current battery technology, though, so with that said, this con is simply more something to be aware of than a true issue.http://demandware.edgesuite.net/aauj_prd/on/demandware.static/-/Sites-masterCatalog_Harman/default/dwcc4bce64/JBL_Flip4_Black_Hero.png
