From the Manufacturer
The JBL Duet multimedia speaker system provides smooth and accurate sound for any portable music player or computer. With its incredibly easy setup and use, Duet is a sophisticated approach to achieving great two-channel sound.
Duet uses patent-pending Tangential Strain Relief (TSR) technology that was designed specifically to deliver extra bass and lower distortion in small enclosures as a result of controlled linear excursion of the speaker. It also provides superior midrange- and high-frequency reproduction.
The neodymium magnet creates more power and sensitivity. Duet also uses a proprietary Adverse Pressure Gradient (APG) port design, which greatly enhances the bass performance.

The bass response is the biggest surprise. It's natural-sounding and open, not stuffy or forced, yet it has a surprising amount of punch for such small speakers, without being the slightest bit "boomy". To my ears in my listening environment, they have an amazingly smooth frequency response across the entire audible range.
In case you think I'm kidding, I usually mix on a pair of Genelec tri-amped studio monitors whose price tag was more than 100 times that of the JBL Duet speakers. On several occasions, I've opened GarageBand or Logic Pro 7 to record a musical idea and ended up doing a rough mix, forgetting that I was listening to the Duet speakers rather than the big monitors. At low levels in a near-field application (...sorry, that's audio geekspeak -- for all you normal humanoids who don't have the audiogeek mutant gene, that means the speakers are close to you...like on your desktop), these little speakers are surprisingly accurate.
I've owned my Duets for almost one year. I loved them so much that I immediately bought extra sets for my kids to use with their iPods. For the money, I've never heard anything better. My thanks to the folks at JBL for creating such a terrific speaker at such a reasonable price.
Having said all that, now that I'm a student and spend most of my time in front of a laptop or else studying, my main criteria for speakers became PORTABILITY, portability, and more portability.
I wanted something light, easy to set up, easy to throw in a bag and travel with, and not nearly as expensive as my Klipsch 2.1's but with a comparable sound value for the price.
I was going to go with 'the other' pair of portable speakers that is popular on Amazon but picked the JBL's for their bass and the fact they were specifically designed to reproduce a 'bigger' sound for their size.
I am REALLY IMPRESSED and VERY HAPPY with my purchase!
These aren't as sleek or portable as 'the other' pair. These will NOT fit comfortably into most laptop bags and while they are small and light, with their shape they will fit awkwardly in an overnight bag.
Also these are NOT usb powered so require more cords, which I hate. However, this means you don't need a computer to listesn to your MP3 player and makes these speakers truly portable speakers for any source with the typical mini plug. And they are portable sized.
But the sound? The sound is GREAT! I listen to a lot of bass heavy electronica and these are PERFECT.Read more ›
When the speakers are playing audio, the sound is great, but when they're not, the buzz is fairly nerve-wracking.
So, if your speakers can be wired away from other computer cables, these are good speakers. But if you need to run the power cable near the other cables, you may get a buzzing sound.

Incredible sound, for so few dollars. Some products have a value proposition that is utterly disproportionate to their cost in dollars. These are such a product. Read morePublished 2 months ago by Forest Hanna
Good for less than Five years.
It is broken now, and is offered by third part sellers only for approx twice the amount the cost was when I purchased it.
Did not work that well, even though had great reviews. Very bulky and inconvenient. I am in a small NY apartment, so need things to be small and efficient.Published 3 months ago by NYC

They are excellent speakers. However, the knob is hard to turn, so I glued a washer to it for a better grip. Now I really like them.Published 6 months ago by K.Blake
