JBL FLIP 4 Speaker Review | The Best Bluetooth Speaker



JBL Flip 4

The JBL Flip 4 may look small, but this portable Bluetooth speaker fills the air with the same full, rich, and powerful sound that has made JBL one of the most respected names in the world of audio. This durable Bluetooth speaker is waterproof so you can bring your favorite tunes with you wherever you go. Whether you are hanging out at the beach, relaxing next to the pool, sweating it out at the gym or taking your morning shower, the JBL Flip 4 brings the party every time.

Here are all the details of JBL Flip 4 Speaker.

JBL Flip 4 All Specifications:

  • Wireless portable Bluetooth speaker
  • Bluetooth version: 4.2
  • Built-in noise cancelling speakerphone for crystal clear phone calls
  • Voice assisted integration makes set up quick and simple
  • Battery Type: Rechargeable lithium-ion Polymer (3.7V, 3000mAH)
  • Up to 12 hours of playback time, 3.5 hour charge time
  • IPX7 waterproof fabric materials make the Flip 4 an all-weather companion
  • Dimensions: 68mm x 175mm x 70mm
  • Weight: 515g


The JBL Flip 4 is essentially a cylinder in shape, 175mm long and around 70mm in diameter (one side, which bears the controls, is a little flatter and wider). It comes with a kind of rubberised fabric finish, available in six colours. That said there is one key difference that makes this a worthy upgrade to the previous model – waterproofing. The fabric that wraps around the speaker might look fairly similar to the previous model, but it’s actually completely waterproof now.

It’s IPX7 waterproof to be exact, which along with being able to be submerged for 30 minutes in up to a meter of water, also means that’s sealed against dust, dirt, and sand. So taking this to the beach was no problem.

You’ll still get the four playback control buttons along the side of the speaker, and the power button and JBL Connect+ along the spine.

That’s also where you’ll get the five indicator lights that show you how much battery life is left along with a small flap to keep water out of the micro USB charging input and the 3.5mm input hidden underneath.

Performance, features and battery

One of the most intriguing features of the JBL Flip 4 is the Connect+ pairing – which allows it to connect to other JBL Flip audio products, producing multi-speaker sound, which should help when listening in larger rooms or big open spaces. The 3,000mAh battery inside is claimed to support up to 12 hours of constant music playing. This, as usual, depends on how loud the music is played, and what kind of music it is to some degree. In our use, it comfortably made it to between 10-11 hours before the battery level indicator suggested it was approaching game over.

General performance is good. So long as the connected device is in the same room as the speaker, the Bluetooth connection remains solid and, in our testing, never dropped out. Only when we moved the music source into the next room, say more than 10 metres away, did the audio start to drop out and be inconsistent.

While all the majority of its features can be enjoyed without a smartphone app, there is the JBL Connect app that can be downloaded for Android or iPhone. This allows you to choose whether you want the “play” button to play/pause music or launch your phone’s default voice assistant. Whether that be Google Assistant or Siri.

You can also use the app to manage how the speaker connects with other speakers; this could be either with one other speaker in stereo mode or connecting to multiple speakers in “party mode”.

Sound Quality

Considering its relatively compact size, the JBL Flip 4 delivers an impressive amount of bass. It might not have the ultra-low frequency response of some much more expensive speakers or headphones (which typically are rated at 20Hz minimum, far lower than JBL’s 70Hz claim), but it still manages to pump out enough of the lower frequencies to fill a small room.

In larger rooms, it’s fine, but you do find the audio can get a little lost if you have an open-plan area, or high ceilings, as you would find with any small speaker. Pump the volume all the way up, and you’ll find the treble/high-frequencies are too harsh, while bass loses its effectiveness at such volume; the low-end also vanishes a bit when you turn the speaker down too low, too, so you definitely have to find a volume sweetspot somewhere in the middle for the most balanced sound results.

At optimum volume, the JBL Flip 4’s overall quality is pleasant, delivering the right balance, with that generous bass filling out the rest of the sound with warmth. Details are pretty good to for a small, affordable speaker. There’s no noticeable distortion and enough clarity to make the listening experience enjoyable.

Audio Quality

JBL Reflect Flow wireless headphones deliver a powerful audio performance with rich, deep bass and crisp highs for a great listening experience, regardless of the music genre.

The strong bass depth may be a boon or a bane, depending on the listener’s preference. While the inaccurate sound signature (that comes off as a bit artificial) of the boosted bass might be a dealbreaker for purists, it could be an advantage for gym rats who are motivated by thunderous bass during workouts.

The JBL Reflect Flow’s 5.8mm drivers deliver a powerful punch with a dynamic frequency response range of 20Hz to 20kHz.

The JBL Reflect Flow use the latest Bluetooth 5.0 standard, which means better transmission distances if you have a smartphone that’s compatible with version 5.0 of the wireless standard. There’s support for SBC and AAC audio codecs, which is great news for users of Apple iOS devices and is now also supported by the latest versions of Android. There’s no support for the apt-X codec, so that could be a deal-breaker for some people.

The Reflect Flow’s mic offers solid intelligibility. When someone calls you while you’re wearing a pair of JBL True Wireless headphones, the person on the other line will more likely understand what you’re saying.

With an IPX7 rating, the JBL Reflect Flow headphones are waterproof and sweatproof. They can withstand immersion in water up to 1-meter deep for up to 30 minutes.

This means the waterproof earphones are protected when you’re wearing them while jogging in the rain, or when you have to rinse it quickly to remove dirt. However, The JBL headphones are not safe for swimming. The charging case isn’t waterproof as well.

The Reflect Flow has two key features: the Ambient Aware and TalkThru technologies. Ambient Aware allows you to hear the surroundings while listening to music for safety purposes. The TalkThru feature lets you carry on a conversation without having to remove your Reflect Flow earphones. Just a touch of a button lowers the volume, so you can hear clearly what the other person is saying.

Fit And Battery Life

The Reflect Flow comes bundled with three different-sized ear tips made of silicon. The package also includes another trio of Freebit enhancers, which are essentially ear wings that fit over the earbuds and secure them in the ears.

The JBL Reflect Flow can play for up to 30 hours using the recharging function of the storage case. The earbuds will play for up to 10 hours on a single charge before they need to be put back in the case for a complete recharge.

The case holds enough charge for a further 20 hours of listening, which is more than enough for a week’s worth of commuting. Even better, a quick 10-minute top-up in the case will provide an hour’s worth of listening time, sufficient for a run around the park or a decent bike ride.
