    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.

    JBL Duet PC Speakers: Yes for some, No for others.3
    I was looking for a 2.0 audio system with superior sound and eventually decided to get the JBL Duet. Being a composer myself, I know what kind of bass I can expect from such small speakers, but was still disappointed a great deal. I listen mostly to symphonic works - classical as well as contemporary film scores - and unfortunately, I can barely recognize them with these speakers. They make bass instruments (most commonly bass drums, but also tubas) sound overly loud, leading to unpleasant bass-booms, while orchestrational detail, whether coming out of strings, brasses, woodwinds, percussion or chorus - is sadly lost in its entirety.

    Being a contemporary classical and film music composer and orchestrator myself, I find that while these speakers are excellent (for their price!) for songs in many genres, they do no justice to symphonic music, with the only exception of the simpler works from the baroque era and fully-solo works from all eras (e.g. solo piano). The true beauty of such music comes from its musical detail, and for their low price, the JBL Duet are unable to satisfy the ears (and mind!) of true lovers of such beautiful music.

    To my welcome surprise, the speakers produce no unwanted noise (e.g. buzzing, clicks, humming, etc) even if both my sound card and speakers are pushed into the maximal volume. Complete silence. However, bear in mind that this may - or may not - change depending on the sound card you use.

    Wi-fi antennas placed in a range of about 8 inch from each speaker may naturally cause unwanted funny noise (the baby monitor from the movie Signs comes to mind), which I believe applies to most non-studio speakers. Keep that 8 inch distance from each speaker and the noise is completely gone.

    In conclusion, if you listen to pop, rock and other rather simple songs and look for 2.0 desktop speakers, these ones may be a good option with their good sound and low price. The high notes are indeed crisp and sound nicely, which I believe is going to appeal to lovers of such music!

    However, if you intend to use the JBL Duet for: symphonic music, music that relies on deep basses (e.g. most electronic and dance music, as well as chillout music) or for films, I certainly do not recommend the JBL Duet.

    (For the purpose of this review, I plugged the speakers into my state-of-the-art professional sound card in my studio. I believe the sound would be even more unsatisfactory if I plugged them into my computer's on-board sound card, as I believe most users would do for these 2.0 desktop speakers. Thanks for reading and I hope you make the right choice for your musical preferences!)

    Great for the Price!4
    I use it for my class, and it works really well. It is very light, but sturdy.

    Crackling/Buzzing Sound1
    Problem #1: As others have stated, there is a horrible cracking/buzzing noise coming from both speakers when the music is soft or is not playing. This is not acceptable.
    Problem #2: I'm surprised at how many people say the speakers sound so great--very mediocre in my books. It sounds like a cheap ghetto blaster from the 80's. You definitely get what you pay for with these light, tiny speakers.
    Problem #3: I agree with others--the knob is not just slightly annoying becasue it's so slippery, you actually can't operate it unless you have both hands free so that you can brace the speaker with one hand (for leverage) and use the other hand to control the knob.
    My recommendation: I recommend trying different speakers. I'm not one to give many bad reviews, I usually have very good luck with most everything I buy, but I thought I'd put in my two cents here so that others can avoid this product, not worth it.
