Cyclone PR1 Pro


Reviewed Nov 2009


Details: Discontinued IEM from Chinese manufacturer Cyclone, succeeded by the PR100 and PR200 under their new ECCI brand
Current Price: N/A (discontinued) (MSRP: $55)
Specs: Driver: Dynamic | Imp: 32 Ω | Sens: 106 dB | Freq: 20-22k Hz | Cable: 4.3’ I-plug j-cord
Nozzle Size: 5.5mm | Preferred tips: Stock Bi-flanges
Wear Style: Over-the-ear or straight down

Accessories (3.5/5) – Silicone single-flange (3 sizes) and bi-flange tips, small clamshell carrying case
Build Quality (3/5) – Housing is made of metal and sturdy plastic. Metal filters are nice but the lack of strain reliefs is a cause for concern
Isolation (3/5) – Ported but still adequately isolating, especially with bi-flange tips; slightly susceptible to wind noise
Microphonics (4.5/5) – Nearly non-existent
Comfort (4/5) – Very typical of straight barrel IEMs. I find them light and comfortable. J-cord can be a bother

Sound (7.4/10) –These have a very natural presentation. The soundstage is very wide and airy, with good positioning and separation. They have tremendous clarity across the range and the level of detail they put out, though not on-par with the RE0, is impressive. They have very gradual roll-off at both ends, which results in well-controlled high and low notes. No harsh treble or bass bloat here. I like the bass especially – it can go down pretty deep, but it never imposes and always stays musical. Their unique, gentle signature really agrees with me and works especially well with live recordings, acoustic music, and anything else that can take advantage of the incredible soundstage.

Value (8.5/10) – The PR1 Pro is stellar value for money when it comes to audio quality. The unique sound signature alone makes them worth the price of admission = there is nothing else in their category that can match the wide open feel of these Unfortunately, the j-cord can be bothersome and many similarly-priced sets offer better build quality.

Pros: Wide, airy sound, great clarity and instrumental separation, comfortable
Cons: Lack strain reliefs on the cords, j-corded
