Coby CVEM79 Jammerz Review

Coby CVEM79 Jammerz
Reviewed Apr 2010

Details: Surprisingly fun-sounding low-end IEM from Coby with cheerful color schemes to match
Current Price: $10 from Amazon.com (MSRP: $24.99)
Specs: Driver: Dynamic | Imp: 16 Ω | Sens: 96 dB | Freq: 12-20k Hz | Cable: 4.2’ I-plug
Nozzle Size: 5.5mm | Preferred tips: Stock single-flanges
Wear Style: Over-the-ear or straight down

Accessories (2/5) – Silicone single-flange tips (3 sizes) and miniature velour carrying pouch
Build Quality (3/5) – Aluminum shells are extremely light and contain metal filters both at the front (nozzle) and the rear (vent). The cable is excellent – soft, tough, and flexible, similar to the Meelectronics cables but a bit thinner and missing a cord cinch. There are strain reliefs on housing entry but strangely none whatsoever on the metal 3.5mm plug
Isolation (2/5) – The massive rear-facing vent betrays a surprising lack of isolation for an IEM
Microphonics (4.5/5) – Very low in a cable-down configuration, nonexistent when worn cord-up
Comfort (4.5/5) – Even among straight-barrel IEMs the CVEM79 stand out in comfort. The housings are short and very light, with flexible strain reliefs and a very compliant fit. I’ve managed to sleep on my side with these with no issues on several occasions

Sound (3.7/10) – The sound of the CVEM79 is decidedly warm and leans slightly toward the dark side. The bass is impactful and extended, albeit lacking in definition – in low end clarity the Jammerz are somewhere between the CX300 and Meelec M9. Drums can sound somewhat hollow as a result but bass bleed is low and the mids are in good balance with the low end. Vocals have warm undertones and good presence. The midrange transitions smoothly into treble, which rolls off gradually at the top end. The overall balance is better than bass-heavy earphones like the Lenntek Sonix Micro and Senn CX300 but still not quite up there with class leaders. Detail and clarity are about what one would expect from earphones with a $25 MSRP, no worse than the JVC Marshmallows/AirCushions, but not better. The soundstage is small and instrument separation is mediocre at best but the overall signature is quite enjoyable in an up-close-and-personal way.

Value (7/10) – The Coby CVEM79 ‘Jammerz Platinum’ are another high bang/buck competitor in the ultra-low-budget category, offering solid build quality and a comfortable form factor in a variety of colors for a bargain-basement price. Though the sound does not impress with detail or clarity, the overall signature is enjoyable enough. Personally, I’ve found my perfect napping IEMs in the Jammerz with their comfortable fit and warm, easy-going sound.

Pros: Fun, warm, and impactful sound, many color options, very comfortable, minimal microphonics
Cons: Poor isolation, no strain relief on plug

  1. Try to find a Philips Music Colors (model numbers: SHE3580, SHE3590, SHE3585, SHE3595) in her favorite color. These are much better-sounding than the Coby set. All the different models are the same except outer design and whether they include a mic or not.

  2. my sister looking for headphones.
