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.

A fundamental message for preparing the heart, mind and body
Format: Hardcover
"Preparing your heart for marriage: Devotions for Engaged couples" is a great devotional that should be used by certain couples who follow a certain type of Christian spirituality to help prepare for married life. As the author Gary Thomas stresses, marriage is an entirely different ballgame from dating. No matter how long (or how short) you've been dating your beloved, living with them and learning how their personality works in daily marriage life is the key. These are 30 pre-marriage devotionals that do not require a Biblical reading with them, and have questions for reflections at the end. First, the pluses of this book. The black and white pictures and the layout of the book is just gorgeous. This is a perfect gift for a couple who has just been engaged. The preparation for marriage is realistic. This book deals with myths regarding a perfect marriage are, what communication is and how to continue to learn to love the other person even when times are tough (it's called taking your marital vows seriously). Now, the issues I have with the book. There is a big emphasis on being sexually pure before marriage. A lot of people will like this approach. However, some of the most religious people I know don't believe in this anymore, and feel this is a lesser sin. Some people who might be open to Christianity might be turned off by the heavy handiness of this subject in this work. This is a very Southern Baptist approach to sexuality. When I read about the author's credentials (teacher and writer in residence at the Second Baptist Church in Houston, TX which is one of the largest fundamental churches in Tx) I was not surprised by his approach. While I understand this approach and there are scriptural references to this approach, it may not be appealing to those questioning the validity of Christianity or to those who are interested in exploring becoming a Christian. Overall, this is a good gift. My Husband and I are an old married couple by now, and we enjoyed the book together and read it in one sitting, discussing the questions at the end. I think this can be used by older married couples. (We decided to revisit our courting days and asked some of the questions at the end of each devotional in past tense). I note the author seems to have devotionals for married couples and has written 18 other Christian oriented relationship books as of this writing. This is good for engaged or newly married couples who have a fundamental bent, or who are willing to either skip the sexual purity chapters or discuss the importance of sexuality in their present married/engaged life.
