JBL® engineers believe that you should never have to sacrifice performance for portability. Introducing the JBL Micro II loudspeaker. The JBL Micro II is the first small, ultra-portable speaker featuring a Li-ion rechargeable battery with 6 hours of playback on a full charge and an LED light to let you know when to recharge, plus a built-in bass port for rich, deep low-frequency sound. With a 1-5/8-inch (40-millimeter) driver, the speaker delivers full-range JBL sound with exceptional bass, yet it’s small enough to fit easily into a backpack or clip onto clothing. It connects to any mobile device or MP3 player with a built-in audio cable and a 1/8-inch (3.5-millimeter) stereo mini jack, and you can even daisy-chain it with other JBL Micro II speakers for a powerful sonic experience. An ideal ultra-portable audio solution for indoor or outdoor playback, the JBL Micro II lets you take great JBL bass with you wherever you go and offers performance, portability and pricing that the competition can’t touch.

Built-in bass port

The JBL Micro II portable speaker is small but muscular. Its built-in bass port generates powerful low-frequency sound that’s superior to the bass output of comparable portable products.

5-hour, rechargeable Li-ion battery

The JBL Micro II has a built-in Li-ion battery that provides up to 5 hours of playback time. You can easily recharge the battery using a micro USB port, which will save you battery hassles and money.

Portable design

Who says you can’t take it with you? The lightweight, compact JBL Micro II fits easily into backpacks or pockets.

Smartcable design

The JBL Micro II portable speaker is always ready to connect and play. And when your source device isn’t connected, you can store the built-in, 11-13/16-inch (30-centimeter) audio cable in the bottom of the speaker to prevent tangling.

LED indicator

A clearly visible LED lets you know when the JBL Micro II’s built-in Li-ion rechargeable battery is low, so you can tell when it needs charging.

Daisy-chain capability

Can’t get enough of a good thing? You can connect the JBL Micro II portable speaker to other JBL Micro II speakers, creating an impressive sound environment.

JBL Micro II is rated 4.5769 out of 5 by 26.
Rated 5 out of 5 by from The JBL Micro II gets it right... sounds awesome! I have both the first generation (On Tour Micro) and this second generation. The sound quality of both is excellent but the Micro II wins for a few reasons. 1. It can get as loud as I want even when plugged in to quiet sources. 2. It has a better charging cable. 3. Although it's not as fancy in style as the 1st gen, it is more protected and has a better length of audio cable. 4. It sounds awesome. Yes, both generations sound almost identical which is amazingly good sounds, but the last bit of volume that the Micro II puts out makes this the one to have. I also noticed that the battery life isn't quite as good as the first generation, maybe 5-6 hours, but it is still plenty useful and lasts for days before needing to get recharged.

Rated 5 out of 5 by from Excellent add on speaker! Pciked up this little speaker from a local Radio Shack, they had a couple to choose from but i had great experience with my other JBL products. I use this with my HTC smart phone for music when im working out in my garage. I like the "soft on" feature, it doesnt just immediately blare when you turn it on. Also no distortion at high volume. It is directional so youll want it pointed in your general direction when listening for best sound. My only complaint is that the retailer didnt stock the other colors, did know till i came to the website, i got the white/gray model.

Rated 5 out of 5 by from Micro Power This little speaker had me concerned at first, I wasn't expecting to get the great sound quality that this little thing can produce. I am overly impressed by the size and sound quality that this speaker produces. I definitly will be buy more JBL products. As of right now I have a set of the P660c Components and they sound awesome. Keep up the great work JBL. Returning comsumer here. Thanks Shawn

Rated 5 out of 5 by from This is awesome. This is the product you need. They say that the battery life is 5 hours. Well, I think it is even more. I use my Micro II a lot, and I have to charge it once a week. It's just the best mini speaker, and no one complains about it you see. And it's not difficult to see why.

Rated 5 out of 5 by from Shocked by its Sound Quality! Bought this for my cubicle, and decided one day to test its capabilities near max volume....I had almost every colleague look around to see where the sound was coming from, and when they saw the Micro II...mouths dropped. For its size, this speaker puts out DARN good sound!! Overall, I am HIGHLY impressed!

Rated 5 out of 5 by from Outstanding sound. I bought these to boost the output from my laptop and what a boost it was. The only thing I would change is adding a little longer pigtail which I have done already. Great little speakers.

Rated 5 out of 5 by from Take awesome sound to more places About the size of a breakfast sandwich, this little amplified speaker punches out some serious fidelity. I primarily use it in the bathroom to provide tunes while showering, etc. The JBL Mini II holds its own over the noise of the shower, even from a few feet away. I like to use it outside, too -- it's a perfect tabletop sound system while you're just taking it easy with friends since it doesn't take up much space and puts out plenty of sound. Highs, mids and lows balance well - no EQ tweaks necessary if your source is clean. I chose this model because Bluetooth speakers drain their batteries faster, and will likewise drain a phone's battery faster.
