Sound Signature

You're probably looking to see how these IEMs stack up on sound. We'll share our thoughts here, although keep in mind this information tends to be anecdotal and subjective.

Volur Sound Signature

The Volur delivers a rich and engaging sound signature, characterized by deep, well-controlled bass thanks to its True Isobaric dual dynamic drivers. The mids are warm and smooth, while the highs are clear and extended, thanks to the tia waveguide. This combination results in a sound profile that is both musical and detailed.

Krypton 5 Sound Signature

The FiR Audio Krypton 5 delivers a smooth, engaging, and immersive sound.

The bass of the KR5 delivers a powerful punch with sub-bass rumbles you can feel - courtesy of Kinetic Bass technology. The midrange is smooth, offering a clear and natural presentation for vocals and instrumentals. The treble is crisp and detailed - but never harsh.

The soundstage is wide, deep, and accurate. Sounds spread far left and right and can sound distant as well. Imaging is also very precise - pinpointing sounds within the mix is effortless as vocals and instruments are well-defined even in busy tracks.


Price and Value

The $2,499 Volur provides a rich and engaging listening experience with innovative driver technology. The dual dynamic drivers in True Isobaric configuration work wonders in delivering an impactful yet detailed bass response, unlike any other IEM on the market. The Volur also features Apex, LID, and tia technology for enhanced clarity and customizable sound and noise isolation.

The $2,999 Krypton 5 offer a premium look and feel with its machined aluminum shells and sapphire glass faceplates.

Our Thoughts

The Volur is a unique hybrid IEM that combines two dynamic drivers for unmatched bass quality and quantity. The True Isobaric technology ensures every bass hit is punchy and distortion-free. Bass isn't the only thing you'll enjoy with the Volur - its smooth midrange and detailed treble makes for an exciting sound that works well with a wide variety of genres. Get the Volur if you love bass and want a fun-sounding IEM.

If you're looking for an exciting IEM with flagship-level clarity, detail, and soundstage, then the Krypton 5 is for you. The Krypton 5 boasts an exciting sound with its tactile bass, ultra-detailed midrange, and smooth treble. The KR5's incredible resolution breathes new life into your favorite tracks and unveils details you've never heard before. Technologies like ATOM XS, Kinetic Bass, and Open Acoustics let you enjoy your music like never before in absolute comfort.

Another IEM to consider in this price range is the 64Audio U18s. The U18s packs an incredible 18 drivers per side and offers a warm sound signature with impactful bass and an immersive soundstage.
