A premium all-balanced-armature IEM using Symphonium's TrueX custom four-way crossover. It is aimed at flagship wired audiophile listening.

The HearWiki takeAI-condensed

The Symphonium Audio Crimson is a premium all-balanced-armature IEM delivering flagship-level dynamics, resolution, and a spacious soundstage with a lively, U-shaped tuning. It offers high-energy, technical performance with strong detail retrieval and precise separation, though its low 6-ohm impedance makes it sensitive to source pairing and eartip choices. This wired, non-ANC model suits listeners seeking an engaging, controlled sound that rewards careful setup.

What works

  • Excellent detail retrieval and separation
  • Spacious, immersive soundstage
  • Lively, energetic tuning with good control
  • Lightweight at just 7 grams
  • Flagship-level dynamics and resolution

What doesn't

  • Very low impedance requires quality source gear
  • Sound varies significantly with eartips
  • Upper treble can be sharp if fit is shallow
  • Demanding to pair well with amplifiers

Symphonium Crimson Sound Review

The Headphone Show14.7K viewsOct 2023

The reviewer finds the Symphonium Crimson to be an exceptional IEM with superb bass and mids, comfortable ergonomics, and impressive technical performance, but criticizes the overly bright and zingy upper treble, which can cause fatigue and unnatural cymbal reproduction. They recommend tip rolling to mitigate the treble and note that while it's a strong product overall, it may not suit those sensitive to treble energy.

Symphonium Crimson: Another Home Run?

Amplify Audio Reviews5.9K viewsMar 2024

The reviewer praises the Symphonium Crimson as a technically outstanding IEM, offering exceptional resolution, staging, and imaging for its $1,500 price, often rivaling far more expensive models. While the bass is well-tuned for a BA setup, it lacks the slam of dynamic or planar drivers, and the treble is airy and extended, which may not suit all listeners. Overall, it's a fantastic value for those seeking high-end performance without the exorbitant cost.
