The next standard.
The Crimson has a bold and captivating sound profile with an incredibly dynamic bass presentation reminiscent of high-end speaker configurations. The integration of our PHAT technology allows the Crimson to build on the Symphonium's signature treble response.
The Crimson's highs are not only smooth but also well-extended, offering first-class resolution with a layered and spacious stereo image. With organic vocals, impeccable control, and authority in the bass range, the Crimson emulates the experience of being in front of a live stage.
The combination of these qualities makes the Crimson dynamically captivating and uniquely fascinating to listen to.

"A close friend asked me right away what I did like about the Crimson and one of the phrases I told him was “It's not cookie cutter. It's new, it's fresh, it's the future.", and I still live by those words. According to Symphonium brochures, it is the new standard, but I much rather prefer to call it the new benchmark." - Nymz Reviews
Reviews
"The Symphonium Crimson is a true marvel in what can be done with 4 high-quality, well implemented, and skillfully tuned BAs and will appeal to many with its balanced nature while surprising with an untouched low end that did not make me yearn for DDs as soon as the song got bassier. Pair that with treble that shines and outresolves ESTs yet remains so non-fatiguing all the while. Midrange is right around perfect as well while potentially missing a bit of weight." nikbr

FLAT + PHAT
The Crimson combines our best technologies, offering a fusion of PHAT and FLAT advancements.
With PHAT technology, which prevents unnecessary frequency inversions or phase cancellations, and FLAT technology, which ensures low impedance and immunity to impedance mismatches, the Crimson is ready for any challenge.

Refined shell design
A different design language means a different look.
The Crimson proudly features a redesigned enclosure refined through extensive community feedback. The enclosure is now shaped to fit comfortably in smaller ears, with a shorter sound port and a gently rounded shape.
The result is an IEM that sits snugly against the ears, ensuring a seamless fit. Constructed from the same high-quality heat-treated T6-AL6061 aluminum alloy, the Crimson is designed for durability and long-lasting performance.

Ever heard of forged carbon?
The Crimson features a new color scheme and a premium forged carbon front panel that pays homage to our brand's origins and resilience.
This composite material adorns the dials of award-winning jewelry, watches, and luxury vehicles. Due to the nature of the material, each dial is a unique masterpiece, meaning no two sets are alike.
Given the status of the Crimson, it is only fitting that this distinctive and premium material finds its place in the design.
Exclusive cable with ultimate versatility.
