Collaborative Design
With popular IEMs such as Timeless and Zero, 7Hz has established itself as a trusted brand in audio quality and innovation. This time, 7Hz collaborates with HBB (Hawaii Bad Boy), a well-known YouTube audio reviewer from the channel Bad Guy Good Audio Reviews, which has over 177,000 subscribers. Known for his expertise, HBB has contributed to the design of various IEMs, bringing a wealth of experience to the Elua’s development.
Dual Dynamic Driver Configuration
The Elua features a dual dynamic driver setup, combining a 10mm liquid crystal polymer (LCP) diaphragm driver with an 8mm LCP dynamic driver. This pairing creates a rich, immersive sound with a full range of frequencies. The upgraded LCP diaphragm offers improved tensile strength, enhancing responsiveness and reducing distortion. Driven by powerful N52 neodymium magnets, these dual drivers provide a seamless and cohesive sound experience, unlike traditional hybrid configurations, by using identical diaphragm materials for smooth integration across frequencies.
Balanced Sound Signature
The dual drivers in the Elua enable precise sound tuning, creating a balanced sound signature. A strong sub-bass shelf with a 10dB boost adds deep, subwoofer-like bass, while precision tuning maintains a flat midrange, delivering tonal accuracy that mirrors a live studio environment. The treble is clear and refined, with a natural tonal curve that aligns with the human ear’s perception, resulting in a sound that is powerful, balanced, and highly detailed, suited for both analytical and professional use.
Detachable Custom Cable
The Elua comes with a custom 4-core detachable cable that features 0.78mm 2-pin connectors. This design allows users to easily swap cables, enhancing the IEM's durability and offering flexibility for a personalized listening experience.

The Big Picture
Pros:
V-shaped sound signature with distinct treble
2-pin cable, flat “braid”
Neutral, well-toned midrange
Excellent sub-bass tone
Good mid-bass shaping
Cons:
No carrying case
Upper treble borders on “too sharp”
Rotated 2-pin connectors are uncomfortable
Occasional treble smudging
Sonic Overview:
7hz is targeting an “analytical but fun” sound with the Eula. They’re leveraging its second driver to add some extra oomph to the lower register without compromising on bass control. I generally like this strategy, as it permits the Eula to maintain a fairly tidy V-shaped sound signature without sounding too exaggerated or bloated. Its mids are warmer than neutral, and its treble has a few peaks for added clarity and separation.

Instruments and voices feel really far and muted. In addition to that I think I have a driver Imbalance, I hear more highs on the left side. I really can't recommend them. I really don't mind the bass, but the real problem is the 1k to 3k region. With EQ they get better but it's not worth it.
Hi there,
Thank you for your review of our product. We're sorry to hear about your experience with the 7Hz x HBB Elua.
We understand that you are experiencing an issue with sound imbalance. To help us determine if the issue is related to the cable, could you please try swapping the left and right sides of the cable? This will help us identify if the problem is with the cable itself.
Once you've done this, please let us know if the imbalance follows the cable or remains on the same side.
We have sent you an email to gather more information, please keep an eye on your inbox.
Sorry for the inconvenience.
