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.

From the creator of the Godot Recipes site!
Format: Paperback
Absolutely loved this, takes you through building 5 different games from start to finish, and explains not only how to do things, but it also explains the why! Throughout the course of making these 5 games, you also get introduced to many of the Nodes within Godot, explanations on how they are used, and gives you some experience using them! Feels good to add more tools into your toolkit as you become more familiar and comfortable using more Nodes. Even though this book is not intended for beginners, I would still recommend this book. It comes with a link where you can download example files and get going with minimal effort, however to get the most out of the book I would try to recreate stuff yourself. I found it very useful for easing myself into trying out 3D development. I've been doing 2D for years, and am currently developing a 2D game in Godot, once I complete that I'll be diving headfirst into 3D and this book gave me a lot of insight, and I feel much better about the whole process.

would have been better as a blog
Format: Paperback
First off, I have read over half of this book, but ultimately decided to put it down because it had a low signal-to-noise ratio. If the second half is filled with magic, I apologize in advance. What I liked: * The author is very honest. He does not shy away from discussing his failures (and successes). * The postmortem on the game "Life of Pixel" was especially good. * Interviews from various indie studios are sprinkled throughout. What I did not like: * A number of pieces of information were already out-of-date. This makes me think that the concepts should have been discussed at a higher level. For example, specifics about game engine costs are discussed. These numbers have changed since E3 of this year. Definitely recheck any information before formulating a plan based on the book's recommendations. * The indie studio interviews are a wasted opportunity in that they each interview has the same set of questions. It's like a questionnaire was sent out via email and the responses were pasted into the book. * When discussing commercial options, such as engines or other software packages, blurbs once again appear to be cut-and-pasted (this time verbatim from the package's web site). * Some of the advice is too broad and too light. For example, when writing about how to create a press release, the author discuss how to write in the active voice. I'm frankly not looking for writing tips in my Indie Game Developer Handbook. * The book is filled with tons of web links. My paperback copy was not so useful here. I ultimately left the book with the impression that the information would have been much better in the form of a blog. The author could have really gone in depth with the parts of the book that shined while keeping the surveys of topics in a form that serves them better (i.e. web links on the web).

Helpful information and Questions to consider
Format: Paperback
As a writer of science fiction and fantasy I had already looked into the physical aspects of the worlds I was creating, but I quickly realized I needed to include society and culture in the worldbuilding. I started a search for information, questionairres, or guidelines to use and found very little that would be helpful to me as a writer. Until I came across this book. It's exactly what I needed. It touches on multiple aspects of beliefs and practices and asks questions to help you think through what you want for your worlds, even if it's mostly backgroud. A very useful tool.
