Waterproof sound

Wherever you go with your smartphone, you've got music with a JBL Flip 4. This rugged portable Bluetooth speaker is completely waterproof — ready for sand, sea, dust, or snowbanks. Passive bass radiators and full-range drivers really crank out the sound, with clarity and punch.

JBL Connect+ app

Download JBL's free control app to your Apple® or Android™ device, and kick your Flip 4 into overdrive. Simultaneously pair two devices with the Flip 4, so you and a friend can take turns as DJ without missing a beat.

Pair two Flip 4's for stereo sound, or go even bigger. You can wirelessly connect over one hundred JBL Connect+ enabled portable speakers for the ultimate field party.

Speakerphone and Voice Assist

When you receive a call on your paired phone, the Flip 4 turns into a speakerphone. Its built-in microphone uses SoundClear® technology to minimize echo and filter out ambient noise so you and your caller can hear each other easily.

Press the Voice Assist button, and access your smartphone's voice command program. So just by speaking into the Flip 4 you can use Siri with your iPhone®, and Google Now with your Android smartphone.

Product Research


Portable Waterproof Design: The JBL Flip 4 Bluetooth speaker features a rugged rubberized housing and a durable fabric material grille which will hold up indoors and outdoors. The Flip 4 is waterproof (IPX7-rated) which means no more worrying about rain or spills; you can even submerge the Flip 4 in water up to 1 meter (3') for up to 30 minutes. Its compact design fits easily into a backpack and it also includes a nylon wrist-strap, so you can take it anywhere with you.

  • The FLIP 4 can only be submerged in water for a short period of time. If the speaker is playing and then submerged in water, it will sound muffled, as anything submerged in water would sound like. Submerging the speaker more than 1 meter and for more than 30 minutes will damage the speaker as the water will penetrate through the waterproof barriers due to pressure.
  • To ensure that the JBL Flip 4 is waterproof, please remove all cable connections and tightly close the cap; exposing the Flip 4 to liquids without doing so may result in permanent damage to the speaker. Do not expose the Flip 4 to water while charging, as doing so may result in permanent damage to the speaker or power source.

Full-Range JBL Sound: The JBL Flip 4 employs digital signal processing to generate room-filling audio from a compact speaker. Using two 1.5625" drivers, a 16-watt amplifier, and dual 1.5" passive radiators, the JBL Flip 4 delivers full-range JBL sound with punchy bass. The JBL Flip 4 stereo speaker can play from either a vertical or horizontal position, so you can place it in a variety of locations for great sound.

Bluetooth 4.1: The JBL Flip 4 is a self-powered Bluetooth (version 4.1) speaker which supports wireless audio streaming (A2DP 1.3/AVRCP 1.6) and hands-free communication (HFP 1.6/HSP 1.2), along with digital voice assistant integration for iPhone (Siri) and Android (Google Now). Up to two devices can be connected with the Flip 4 at once, so you and your friends can take turns streaming music. Once paired, the JBL Flip 4 will automatically re-connect with paired devices when in wireless range (up to 33').

  • Wireless Audio Streaming: The JBL Flip 4 portable speaker streams stereo music wirelessly from Bluetooth-enabled devices such as your smartphone, tablet, computer, laptop, or other device. You'll be able to control Play, Pause, & Skip functions from the speaker. You will need to continue to use your Bluetooth-enabled device for advanced music navigation and to view song/artist information.
  •  Hands-Free Communication: The JBL Flip 4 has a built-in microphone with echo and noise cancellation technologies, so you can use it as a hands-free speakerphone for your smartphone (including iPhone or Android). Use the Flip 4 to answer phone calls, talk on Skype, or with Facetime. You will continue to use your Bluetooth-enabled device to view video calls, manually enter phone number, and control advanced phone functions.
  • Voice Assistant Integration: The JBL Flip 4's built-in mic can even act as an extension of the microphone on your Apple iPhone 4S and newer or compatible Android smartphone, so you can access Siri & Android's digital voice assistant (like Google Now). Simply press the Play/Pause button to activate your device's digital voice assistant. You will need to set this feature up through the JBL Connect App on your Apple iOS or Android mobile device.
Note: When the digital voice assistant is enabled through the app, the Play/Pause control function for wireless music streaming is disabled.

JBL Connect App with JBL Connect+: Use the JBL Connect App (for Apple iOS 8.0+ or Android OS 5.0+) to wirelessly link multiple JBL Connect+ enabled speakers, like the JBL Flip 4, together for amplified sound. You are able to link two speakers together so each speaker acts as a left or right channel for stereo sound. You can also link up to 100 speakers together so each speaker plays back both left and right channels for playback of the same Bluetooth source from multiple speakers. Software updates for the speaker can also be done using the JBL Connect app.

Aux Input: In addition to built-in Bluetooth, the JBL Flip 4 is fitted with a 3.5mm auxiliary input for connection of almost any portable audio player with a headphone output.

Rechargeable Battery: The JBL Flip 4 stereo speaker has a built-in Lithium-ion polymer rechargeable battery (3.7V/3000mAH) that provides up to twelve hours of playback time. The Flip 4 speaker includes a microUSB port and a 40" microUSB-to-USB cable to aid in charging the built-in battery. The battery can be recharged from a 3rd party USB/AC power adapter (sold separately) or a free USB port on your computer. A full battery charge takes approximately 3.5 hours.

LED Indicators: Clearly visible LED let you know when the built-in battery needs to be recharged, as well as when the JBL Flip 4 is in Bluetooth listening or pairing mode.

Price point, features, and name brand. [ Gregory  Jul 05, 2017 ]
In stock, shipment free, receipt within 3 days - how can you beat that? [ William  Jun 03, 2017 ]
Was deciding between this or the UE Wonderboom. They both seem like great options and I am sure I would be happy with either but the sound quality on the Flip 4 vs the Wonderboom in the all of the videos that I watched just seemed like this was so much clearer and crisper versus the more muddy, over-bassy Wonderboom (and I listen almost exclusively to EDM). It honestly seems to outperform the Charge 3 on clarity, with a sacrifice on some bass. I guess I'll find out when it arrives! [ Jay  May 30, 2017 ]

Excellent reviews online and waterproof. [ Randolph  Mar 18, 2017 ]

Previous owner of flip [ NESTOR M  Aug 24, 2017 ]
It's unique looking. All my friends have these in various colors, but I'll be the first with a camouflage. Had a JBL Charge 2, and absolutely loved the sound quality. Hopefully this one adds up! [ Justin  Oct 15, 2018 ]

Have previous experience with JBL products, love the sound quality! I was looking for something to take to work with a small footprint but could sound great! The camo-color was fun choice over the traditional colors. [ Jesse  Jun 13, 2018 ]

This is what my grandson wanted. [ Joan  Dec 09, 2017 ]
Love JBL and the Camo color ! [ Christopher  Aug 21, 2017 ]
I golf quite a bit. I go to have fun and a few adult beverages. We always play music while we are in the golf cart. This will work great and small enough to transport in the golf bag. I have a cheaper speaker, but the batteries go dead before we are finished playing. This 12 hour battery life should be perfect. [ Gerald  Aug 06, 2017 ]
Bought one for myself and my brother in law liked it so much, he asked me to buy him one as well. [ W  Nov 12, 2018 ]
got an email on it, had a credit, so why not. [ Richard  Oct 18, 2018 ]
Great sound and great price! [ Maya  Aug 21, 2018 ]
my daughter had one and i thought the sound was unbelievable good. Nice base. I thought she was playing her music through a much bigger and more expensive speaker. This speaker has better components than the same priced BOSE. [ Doug  Jun 28, 2018 ]
Good features and reputable brand [ Steven  May 25, 2018 ]
My brother has the portability and rich, clean sound [ MAURICE  May 05, 2018 ]
per descriptions it fit our needs. [ Jim  Jan 12, 2018 ]

My son requested it for Christmas and I knew Crutchfield was a reputable company. Also the item is sold locally but was not available in gray. Thank you! [ Denver Clark  Nov 30, 2017 ]
I heard a JBL Flip 4 that a friend owns. It sounded great for the size. [ LAMONT  May 16, 2017 ]
I chose this because the sound is told to be very good and I wanted a cute, water proof , portable , and good sounding speaker, This seemed to fit all of my needs. I would have gotten white but because of my fear of getting it dirty grey was my 2nd best option. [ carole  May 08, 2017 ]

Past experience with bbl speakers. [ KEITH  Jul 01, 2018 ]
I wanted a good sound on a budget. My daughter owns a JBL Flip 2 and is good enough. I just need louder music while cleaning the house, but something I can take to pool and beach. I can't afford something more expensive, and according to reviews, this one will satisfy my needs. [ Nidia  Jun 03, 2018 ]

5 questions already asked

I don't know if it fits a bike water bottle mount, but I would guess that it would. But it sounds unbelievably good for such a small unit. I own a recording studio so I'm picky. I think this unit is the best small speaker currently on the market. [ Robert C.  Aug 14, 2018 ]
Yes [ Miguel  Apr 18, 2017 ]
What do you mean by mount, attach permanently? Kind of defeats the purpose of buying a portable speaker. I use the included tether and just hang it up wherever its convenient. I would attach a hook to the pergola and just hang your Flip 4 from the hook, like a hanging flower pot. If you don't trust the knot in the tether, add a clasp to secure the knot. [ Dominic  Apr 18, 2017 ]
My guess would be that it could become wet and then dried and not damaged. But it would not hold up to being left in the weather for an extended period of time. Freezing weather, snow and extended wet weather. [ JOHN  Nov 17, 2017 ]
Yes you can. You can pair of the two speakers together so that you get sort of a virtual stereo effect. [ Morris  Jul 04, 2017 ]
Thanks for your question. Delivery within the U.S. is generally within 2 to 3 business days after the order ships. Hope this helps. [ Kenny  Jul 25, 2017 ]  Staff
