Details: ‘Pro’ version of the Le01, boasting better build quality and enhanced bass
Current Price: N/A (discontinued) (MSRP: $50)
Specs: Driver: Dynamic | Imp: 40 Ω | Sens: 112 dB | Freq: 12-26k Hz | Cable: 4.3’ I-plug
Nozzle Size: 5.5mm | Preferred tips: Stock Bi-flanges
Wear Style: Over-the-ear or straight down
Accessories (2.5/5) – Single-flange (3 sizes) and bi-flange silicone tips, Soundmagic-style black foamies, and shirt clip
Build Quality (3/5) – Same plastic/metal housing as the PR1 Pro and R02ProII but with half-length strain reliefs and the same thin, tangle-happy cord as the Le01
Isolation (3/5) – Very adequate for a ported dynamic IEM, especially with bi-flange tips
Microphonics (4.5/5) – Nearly non-existent when worn over-the-ear; very low otherwise
Comfort (4/5) – Just a bit heavier than the all-plastic Le01, the Le01+ is still a very comfortable IEM whether worn cord-up or cord-down
Sound (5.3/10) – The Le01+, besides offering a better build than the Le01, “improves” on the sound by adding a large mid-bass hump to the sound signature. Though the mid-bass is downright overpowering at times, the tuning also improves low-end extension and the Le01+ can drop below an impressive 25Hz. The boom found in the bass of the Le01 is magnified by the hump, which is also large enough to creep up on the lower midrange and makes them sound a good amount warmer and darker than the Le01. The resulting sound smoothes over some fine detail and causes a loss in the crispness of the Le01 but provides for a less grainy and ‘plasticky’ overall sound. The change from the Le01 is personally not to my liking but the signature of the Le01+ is certainly a more popular one.
Value (6/10) – The Le01+ is recommended only for die-hard bassheads. Tuned for the maximum possible mid-bass response, the resulting mountain of bass negatively affects mid-range detail, clarity, and separation. Though the sound becomes fuller and smoother, the drop in resolution is detrimental to my personal enjoyment of the earphones. I feel like the Le01 is more of an audiophile set despite its small flaws while the pricier and better-built Le01+ is geared toward the mainstream market.
Pros: Bassy, smooth, and more organic-sounding than the Le01
Cons: Mid-bass can be excessive, sound is not as clear and detailed as the Le01, tangle-prone cabling, no cord cinch
