Open-back headphone designs are often higher-performance but have poor noise isolation and leak sound. Closed-back designs provide better noise isolation and leak less sound.

Check out Precogvision's video review of the Symphonium Audio Helios In-Ear Monitor Headphones below.
Introducing the Symphonium Audio Helios, a Headphones.com North American exclusive in-ear monitor headphone priced at $1099.
The Helios is a true competitor in sound quality alone in the $1k price bracket and delivers bass unlike any other balanced armature IEM before it. The fit on the Helios is rather large though so for those with smaller ears, they may not be the right fit for you.
From Symphonium Audio
Representing a generational leap for us, Helios was designed to disprove the stereotypes associated with multi-driver balanced armature earphones. Utilizing newly developed technologies, our balanced armature subwoofers produce exceptionally clean sub-bass punch that hits hard, yet does not colour vocal presentation. Tuned for a smooth and detailed midrange, the Helios also features class-leading treble extension that pushes the limits of what balanced armature tweeters are capable of. We combined the best features of different monitors into a single product.
Powered by an integrated 4-Way crossover, the Helios is sure to impress with its dynamism and vigour. We never fail to push the limits.
Infinite Linearity
Featuring Filtered Linear Attenuation Tuning (FLAT) Technology, a propriety circuit developed in-house with Subtonic, Helios will not be affected by impedence 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.
Custom Cable
A great earphone deserves a cable of equal quality. As such, each Helios comes with a low impedance hand-built 26 AWG OCC Copper cable from Altalune Audio that has been carefully designed - down to the solder used - to provide the best listening experience possible.
Durability
All Symphonium Audio In-Ear Monitors are made of machined AL6061 Aluminium alloy. The T6 Variant of AL6061 is artificially tempered to provide the maximum possible strength and hardness for our In-Ear Monitors.
