The Technical Reference

The Helios is a statement class product that represents a generational leap for us.
Recognized for it's legendary technical ability, the Helios disproves the stereotypes commonly associated with multi-BA driver earphones. The Helios offers an exceptionally clean sub-bass punch that hits hard, without coloring the clarity of vocal presentations.

Tuned for a smooth and detailed midrange, the Helios also features class-leading treble extension that pushes the limits of balanced armature tweeters. We combined the best features from different monitors into one exceptional product.

Powered by an integrated TrueX™ 4-Way crossover and FLAT™ technology, the Helios is sure to impress with its dynamism and vigour and will deliver an unrivalled audio experience.

Tuned in Collaboration with Subtonic

Infinite Linearity

Featuring Filtered Linear Attenuation Tuning (FLAT™) Technology - a proprietary circuit developed in-house with Subtonic.

Working synergistically with Helios’s TrueX™ 4-way crossover, the Helios will not be affected by impedance mismatch due to difference in source used. You will be able to listen to the same unimpeded sound regardless of the device you are using.

Premium Cables

The Helios comes bundled with premium quality Altalune Audio Nova 26AWG Type 2 Litz OCC copper cables that are designed to deliver an exceptional listening experience with great ergonomics and low impedance.

Each cable is designed down to the finest details such as solder used and are completely hand built in Singapore.

Exceptionally Durable

Crafted from high-grade T6 heat-treated AL6061 Aluminium alloy, the Helios is engineered for durability and long-lasting performance. The T6 heat treatment significantly improves its strength, hardness, and durability while also enhancing its resistance to corrosion and fatigue. This gives the maximum possible strength and hardness for our IEMs, ensuring that the Helios can withstand even the most rigorous use.

Whether you're performing on stage or listening on the go, the Helios Earphone is built to last

TrueX™ 4-Way Crossover

By utilizing a true 4-way crossover, we are able to tune each driver to the exact specifications we require to achieve the best possible sound.

PrecisionMatch™

Each earphone undergoes rigorous channel matching and reference matching with PrecisionMatch™ technology to guarantee a superior listening experience.

Quality Eartips

To squeeze out every last bit of performance, the Helios comes with Azla Sednafit Standards for an uncompromised listening experience.

No scent and blends in surprisingly well.
Style: 4 Fl Oz (Pack of 1)
Eucerin 50 (Sensitive Mineral - Zinc Oxide) Expiration date: Sept. 2026 Purchase date: May 2025 The most noticeable ingredients in the sunscreen are zinc oxide, mineral oil, and a yellow tint. The sunscreen is not scented which is always a plus. The yellow tint was not noticeable on my deep bronze skin. My skin is sensitive to many chemical products but not this one. The product blended in well into my skin both when dry and when using a moisturizing toner. There was not a white cast after giving it a few minutes to be absorbed by the skin. Most oil-based sunscreens leave my skin feeling greasy when perspiring but the Eucerin 50 was a pleasant surprise. The perspiration felt normal and not greasy. Overall, I am very pleased with the product. It is great for active people who normally sweat away sunscreen. Eucerin 50 left my skin feeling very soft after washing it off. This is the first mineral oil-based sunscreen that I have found to be satisfactory. I believe it to be a good value at the twenty-dollar or less price range. Warning!: It can stain your clothing. Do not store oil-based sunscreens in a hot environment like your automobile. The ingredients will separate.

I've tried MANY sunscreens. This is the best for the money you can buy.
Style: 4 Fl Oz (Pack of 1)
I have a section in my closet reserved for the graves of past sunscreens. And there are A LOT. Reasons why this is the best for price point: 1. No white cast. Maybe 2%. Yes, there is a bad a white cast when you first put it on, especially if your face is still a tad damp from washing. But it almost completely disappears within minutes. And this is coming from someone who is of Southeast Asian descent, and currently have a natural a tan this time of year. I get tan because I don't apply it every 2 hours as recommended. I only use it when I'm working out outside and the sun is blasting my face. I live where it gets very sunny. 2. NOT oily. I have super oily skin and so many of my sunscreens makes my face more of an oil slick than normal. I have matiffying ones, that work well, but it gets expensive. 3. Fragrance free! I prefer to use as many fragrance-free products as possible. 4. DOESN'T STING EYES. I'm surprised at how many "sunscreens for the face" are out there that absolutely sting my eyes into waterworks. 5. Price-point. A giant tube (for the face) for all that? It will take me a very long time to go through it. For my body, I use cheaper fragrance-free mineral sunscreens, or sunscreens I want to get rid of. 6. I use a moderate strength prescription of Tretinoin, and those who know, know that without sun protection, the skin can get burned and irritated extremely easily. Not me! And I use Tretinoin every single night. I'm so glad Eucerin made this, I hope they never discontinue this!

Awful for normal/combo skin types!
Style: 4 Fl Oz (Pack of 1)
Terrible for normal/combo skin! I applied sunscreen to my clean, dry face – without moisturizer. After waiting 25 minutes, I checked to see if the product hadn’t absorbed into my skin. It remained on top of my skin in a shiny, slippery, greasy film that rubbed off onto anything it touched. It’s settled thickly into crevices and fine lines, especially in the folds of my eyelids. There was so much shine – not glow – on my skin that it created flashback when I took a picture. Somehow, the sunscreen made my skin appear both oily and dry at the same time! Many other reviewers said that they successfully put make up over this sunscreen, but I cannot imagine how this would be successful, unless the makeup finish was incredibly matte. It’s the worst experience I’ve ever had with any sunscreen!

A perfect product for me!
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
This product is so convenient for travel. I am very fair and used this exclusively on my face and neck on my recent trip to South Africa. No sunburn, no smell, easy on, no breakout on my face. A perfect product for me!

My Family's Favorite Sunscreen!
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
This is our go-to sunscreen and my family has not used any other brand since discovering it about 5 or 6 years ago. The scent is pleasant, light, and tropical. Application is quick and easy. It goes on clear (not white) and looks a little greasy at first, but that is actually a positive because it helps you quickly see spots you (or your child) missed. It soon absorbs cleanly and the oily feeling goes away after a few minutes. The sunscreen works really well. My family has very pale, sensitive skin with eczema and easily burns in the sun. It does not irritate our skin at all and provides great coverage. This stuff works very well for us on vacation in Florida and on Bahamas/Caribbean cruises. It fits easily in a small bag and doesn't take up much room. With it being a solid, there's no worry of leaking. I love that you can hand everyone a stick and they can do most of the application themselves. Then we turn around and get the hard to reach spots on each other. And all done with clean hands that aren't getting messy. I would be so sad if this sunscreen is ever discontinued. We have over a dozen sticks in our house/car/luggage at any given time.
