Third-party reviews

What customers like about Rock Jaw Alfa Genus V2

  • Versatile sound with three swappable tuning filters (Silver: Bass, Gold: Natural, Black: Treble)
  • Exceptional value for money, competing with more expensive earphones
  • High-quality, durable build featuring lightweight aluminum housing
  • Comprehensive accessory package including various silicone and foam tips, a shirt clip, and a carry pouch
  • Tangle-resistant thick rubber cable with a robust L-shaped jack

What customers don't like about Rock Jaw Alfa Genus V2

  • Heavy cable that may pull on the ears without using the included shirt clip
  • Occasional microphonics (cable noise rubbing against clothing) due to the thicker rubber design
  • Swappable filters can be difficult to remove from the packaging foam and are easy to lose
  • In-line remote button may rattle slightly in some units
  • Soundstage depth is somewhat limited, though width and height are respectable

Verdict

The Rock Jaw Alfa Genus V2 is a versatile pair of in-ear monitors featuring 8mm dynamic drivers and a unique interchangeable tuning filter system (Silver for bass, Gold for natural, and Black for treble) that allows users to customise the sound signature. These wired earphones are constructed with a durable yet lightweight aluminium casing, weighing only 9 grams, and come equipped with a 1.2m anti-tangle rubber cable terminating in a gold-plated 3.5mm right-angle jack. Technical specifications include an impedance of 16Ω, sensitivity of 108+/-3dB, and a frequency response of 20Hz to 20,000Hz. Main pros include its highly customisable audio, robust build quality, and a generous accessory package that includes memory foam and double-flange eartips. However, notable cons include significant cable microphonics (noise from the cord rubbing against clothing), a soundstage that lacks depth, and a slightly heavy cable that may require the included shirt clip to stay secure.
