FLAT + PHAT

Featuring a combination of our finest technologies, the Crimson boasts a fusion of both PHAT and FLAT advancements.

With PHAT technology ensuring no unnecessary frequency inversions or phase cancellation and FLAT technology ensuring low impedance and immunity from impedance mismatch - the Crimson is ready to take on any challenge thrown it's way.

Refined Shell Design

A different design language means a different look.

The Crimson proudly presents a redesigned shell, refined through extensive community feedback. The shell is now thoughtfully shaped to comfortably fit smaller ears, featuring a shorter nozzle and a gently rounded form.

The outcome is an IEM that rests snugly against the ears, ensuring a seamless fit. Made from the same high-grade T6 heat-treated AL6061 Aluminium alloy, the Crimson is engineered for durability and long-lasting performance.

Say Forged Carbon?

The Crimson boasts a new color scheme and a premium forged carbon faceplate that pays homage to our brand's origins and resilience.

This material composite has graced the works of award-winning jewelry, watch, and luxury vehicles. Due to the material's inherent nature, each faceplate is a unique masterpiece, ensuring no two sets are the same.

Given the Crimson's status, it's only fitting that this distinctive and premium material finds its place within the design.

Saved me so much money
Im loving this mattress topper. It has added a noticeable layer of comfort to my firm mattress without making it feel too soft. The cushion is plush yet supportive and has made sleeping more comfortable overall. The bamboo feels soft and breathable. It fits on the mattress with the deep pockets and stays in place alk night. Setup was easy and it fluffed up after unpacking. If you have a firm mattress and want extra comfort without replacing it, this topper is a great option. Highly recommend

Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.
This 3-inch mattress topper instantly upgraded my bed with a softer, cooler, and more supportive feel. The bamboo-viscose fabric is noticeably breathable, helping regulate heat throughout the night—great for hot sleepers. The 1200GSM down-alternative fill adds plush, cloud-like cushioning while still offering balanced support for the back and shoulders. It fits securely with the deep pockets and stays in place even when turning. After allowing it to fully expand, the topper fluffs up beautifully. Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.

Great upgrade for a rental apartment mattress
The mattress in my rental place is firm to the point where it almost feels unfinished. Instead of replacing it, I decided to try adding this topper. It made an immediate difference in the way the bed feels when I sit or lie down. There’s a nice cushioned layer that softens that “flat” feeling but still holds its shape. Another thing I noticed is how breathable it is. I expected thick padding to feel warm, but the airflow here feels better than the original mattress surface. Even after moving around, it never felt heavy or stuffy.

Soft and Comfortable Topper
I got this bamboo mattress topper for a small single bed we keep in our guest room, but I ended up testing it out myself first. The material feels soft and breathable, which is nice because that room can get a little warm in the afternoons. It adds a good amount of cushioning without making the bed too soft. After a couple of nights, my back actually felt better compared to the old mattress alone. I also appreciate that it’s machine washable, because our guest room sometimes doubles as a nap spot for my son after swim class, and spills happen. It dried pretty quickly in the dryer and kept its shape. Overall, it made the bed feel much more comfortable and fresh.

Added comfort for someone working night shifts
I work odd hours, so my sleep schedule is all over the place. My mattress has always felt a bit too stiff after long shifts, so I got this topper hoping it would help me relax faster. It really changed the overall feel of the bed. The padding has a cushioned lift that makes lying down feel smoother, especially around the shoulders and lower back. Instead of feeling like I’m dropping onto a firm surface, there’s a soft layer that evens out the pressure. What surprised me most is how light the surface feels. Even after staying in one position, it never gets stuffy or heavy. The airflow makes a difference when your body is trying to wind down after work. The fitted pocket also stays tight around the mattress, so nothing shifts when I move. I can stretch out without worrying about the topper sliding off.
