RadioPaq Jazz Review

RadioPaq Jazz
Reviewed Nov 2009

Details: One of the four RadioPaq IEMs ‘acoustically tuned’ for different genres
MSRP: £60.00 (approx. $100) (discontinued)
Current Price £27 (approx. $44) from amazon UK
Specs: Driver: Dynamic | Imp: 16 Ω | Sens: 120 dB | Freq: 18-20k Hz | Cord: 3.9’ I-plug
Nozzle Size: 5mm | Preferred tips: Stock tips, VSonic $2 foamies
Wear Style: Straight down or over-the-ear

Accessories (1/5) – Silicone single-flange tips (3 sizes)
Build Quality (4/5) – Metal housings have a very solid feel and classy looks. Metal nozzle is very sturdy although the lack of filters is pretty odd-looking. Cabling is strong but plasticky and a cable cinch is nowhere to be found
Isolation (2.5/5) – Fat housings make it difficult to get a deep seal but they can isolate well even with stock tips if a good fit is achieved
Microphonics (3.5/5) – Pretty average when worn cord-down, much better over-the-ear
Comfort (2.5/5) – Shells are quite large and weighty. Insertion is shallow and they can sometimes break seal or even fall out, requiring re-insertion. If inserted deeply enough the edges of the housings can hurt ears

Sound (6.8/10) – Sound is warm and dynamic. Definitely cannot be called analytical, but can be more fun than the proverbial barrel of monkeys. Soundstage is just a bit wider than average but instrumental separation is quite good. The high end boasts good extension and plenty of detail for a budget-oriented dynamic IEM but has some peaks. The mids also boast good detail and clarity but are somewhat recessed compared to the bass and treble. They need a very good seal for the optimal bass experience, but can be incredibly deep and smooth. Bass often feels layered over the mids rather than integrated, yielding a pretty unique sound signature. The treble can be slightly hot-tempered on some tracks but remains sibilance-free nevertheless.

Amplification – not required to enjoy the smooth, easy-going sound. However, a good neutral amp will bring out more detail and make the Jazz more accurate and balanced all-around performers.

Value (8.5/10) – The RadioPaq Jazz is a very interesting earphone at its price point. It provides a big, powerful, smooth, and warm sound that keeps it true to its name, and does all this at a bargain-basement price. Should be especially high on the short-list for European Head-Fiers who may have an easier time acquiring one of these than, say, a Nuforce or Maximo product. Price fluctuates wildly, so adjust accordingly. At the lowest-to-date £27 price, these are nothing short of unbeatable.

Pros: Good looking, sturdy, lots of fun, excellent bass and very smooth-sounding overall
Cons: Lacks accessories, large size can lead to fit issues
