ROCK Zircon Sport (RAU0510)
Ø8mm Dynamic Driver

The sports variant of the Champion of AudioBudget: ROCK Zircon. Soundwise, these earphones are identical to the original Zircon. However, Zircon Sport's design makes them much less universal when it comes to comfort. I, for once, couldn't get them in my ears properly at all. I had to hold them with my hands to hear them. They might fit you though, but for this sole comfort issue they lost a point.

Recommended for: Average listeners & bassheads.

Pros
Cons
  • Exceptional sound quality. The bass is immersive and surrounding, the mids are precise and the highs are smooth and crisp.
  • Unbeatable build quality and a generous use of quality materials.
  • A one-size not-so-universal fit. Either they fit you well, or they won't fit at all.
  • A few extra accessories besides the ear tips would be great.

Comfort & Fit

These earphones aren't as universal as the original ROCK Zircon. They might fit some, but they didn't fit me at all, I couldn't put them inside firmly and couldn't get a seal.

Lows / Bass

The bass is not just powerful and deep, it also doesn't muffle the mids and highs at all. This is the most enjoyable balance between lows and mids ever. These drivers handle deep bass music styles easily, like Dubstep and Trap.

Mids / Vocals

The mids are clear and precise, even though not micro-detailed. Even when the bass is kicking hard, the mids stay stable and consistent at all times. The vocals sound full and surrounding, gives you the feeling of presence in front of a stage. The channel separation is amazing. The vocals get bright but never sibilant.

Highs / Treble

The highs are loud and sharp, but not sibilant and not painful. They are perfect for extended listening sessions.
