Frequently asked questions
About CROOFLUID & The Headphones
Q1. What is CROOFLUID? Are these really ferrofluid headphones?
Yes. CROOFLUID is our signature over-ear headphone that combines immersive sound, active noise cancelling and a live ferrofluid display on the earcup. The dark liquid you see inside the window is real ferrofluid that responds to a magnetic field, creating smooth, organic shapes that move with your audio in real time.
Q2. Can I see the ferrofluid moving while I’m wearing the headphones?
You won’t see it directly while wearing them, but people around you will. The ferrofluid window is designed as an outward-facing visual – perfect for content creation, streaming, travel and daily use. When you take them off, you can also enjoy watching the movement up close.
Q3. Are these headphones only about the visual effect, or do they actually sound good?
The visual is a big part of the experience, but we designed CROOFLUID to be your daily driver, not just a toy. You still get: • Rich, detailed sound for music, movies, and games
• Active noise cancelling and transparency mode (where available)
• Comfortable over-ear cushions for long sessions
• Stable Bluetooth connection and low-latency game mode
So even when you turn off the magnetorheological lighting, it remains a complete and enjoyable wireless headset.
Safety & Ferrofluid
Q4. Is the ferrofluid safe?
Yes. The ferrofluid we use is non-toxic and fully sealed inside a dedicated chamber. It never comes into contact with your skin or the outside environment during normal use.
Q5. Will the ferrofluid leak or dry out over time?
The ferrofluid is enclosed in a sealed capsule made from durable, transparent material. Under normal use it will not leak, evaporate or need to be refilled. Please avoid exposing the headphones to extreme heat, sharp impacts or intentional disassembly, as that can damage the chamber.
Q6. Does the ferrofluid affect sound quality?
No. The ferrofluid display is separated from the acoustic chamber. It’s there for visual expression only and does not interfere with the driver or tuning of the headphone.
Features & Usage
Q7. How long does the battery last?
Battery life will vary with volume and whether noise cancellation/lighting is on, but in typical use you can expect up to around 48 hours of playback on a full charge in standard Bluetooth mode. Battery life will decrease slightly when the ferrofluid effect and ANC are enabled; this is normal.
Q8. Can I turn off the ferrofluid effect and lights?
Yes. You can switch off the visual effect when you want to save power or stay in low-profile mode. In “visual off” mode, it's a clean, minimalist high-end headphone.
Q9. Are they comfortable for long listening sessions?
CROOFLUID uses soft over-ear cushions, a padded headband, and a balanced clamping force to distribute the weight evenly. Most users can wear them for several hours continuously and still feel comfortable. If you're not used to it at first, we recommend adjusting the headband length and angle to find the most comfortable position for you.
Q10. Do they have Active Noise Canceling (ANC)?
Our headphones include digital hybrid ANC (spec may vary by batch / region). You can switch between ANC, transparency and standard modes depending on your environment.
Q11. Can I use them wired as well as wireless?
CROOFLUID connects primarily via Bluetooth. If your version includes a 3.5mm audio port, you can also use the supplied audio cable for wired listening (for example, on airplanes or with dedicated audio gear). Please refer to the actual product accessories you receive.
Q12. Are the headphones water-resistant?
CROOFLUID is designed for everyday indoor and light outdoor use, but it is not a waterproof or sports headset. Please avoid heavy rain, submersion, showering or using it in very humid environments.

Q13. Where do you ship from and which countries do you ship to?

Q15. Do I need to pay customs duties, VAT, or import taxes?
Depending on your country’s regulations, you may be charged VAT/GST, customs duties, or customs clearance fees. Unless explicitly stated as “Duties & Taxes Included” at checkout, these fees are usually borne by the recipient. Please consult your local customs office for more accurate information.
Q16. Can I change my shipping address after placing an order?

Care, Cleaning & Other Questions
Q21. How should I clean and care for my CROOFLUID headphones?
• Use a soft, dry cloth to wipe the headband and ear cushions
• Avoid alcohol, strong detergents or solvents

• Store the headphones in a cool, dry place, preferably in a protective case
Q22. Can I use CROOFLUID for gaming and video calls?
Yes. Thanks to low-latency Bluetooth mode and clear microphone pickup (subject to the actual situation of your product), CROOFLUID works well with PC, consoles (via Bluetooth or cable, if supported) and mobile devices for games, streaming and online meetings.
