Refined Harman Curve Tuning

Harman Curve tuning is an audio standard developed through extensive auditory research, designed to enhance the listening experience by aligning with the natural characteristics of human hearing. By carefully adjusting the frequency response, it delivers a more balanced and natural sound. While many flagship models incorporate a Harman-style tuning, ND takes a different approach. Through innovative acoustic design and advanced hardware, ND refines traditional tuning methods to achieve a well-crafted and fitting Harman Curve sound.

Planetary Design & Craftsmanship

Inspired by celestial bodies, Planet blends cosmic aesthetics with high-fidelity sound. The highly transparent resin cavity reveals its precise internal structure, while the planetary texture and sleek black Hi-Fi cable add a refined touch. With meticulous tuning and a large dynamic driver, Planet delivers a natural and immersive sound. Every detail is crafted to balance artistic design with high-performance audio.

Advanced Hardware for an Immersive Experience

Planet is equipped with a next-generation 12mm dual-magnetic, dual-cavity beryllium-plated dynamic driver, designed for enhanced transient response and precise performance across a wide frequency range. The dual-magnetic circuit strengthens magnetic force, expanding the soundstage for a fuller, wider, and more immersive audio experience. With its refined balance of delicacy and power, Planet delivers a dynamic and captivating listening journey.

Beryllium-Plated Driver for Powerful Sound Performance

The latest-generation beryllium-plated dynamic driver has undergone years of refinement and thousands of prototype tests, achieving a 20% performance improvement. Enhanced efficiency delivers better resolution, dynamics, and transient response, significantly expanding the frequency range for richer details. With a 32Ω impedance, 20-40kHz frequency response, and 112dB sensitivity, it produces a wide soundstage with deep, impactful dynamics, capturing the energy and realism of live music while pushing the boundaries of sound quality.

Precision Acoustic Design for Immersive Sound

The independent cavity design, combined with precise acoustic simulation and path optimization, minimizes interference and enhances sound clarity. Through careful tuning and spatial engineering, it creates a stereoscopic surround sound experience, immersing you in a vast auditory space that captures the depth and atmosphere of live performances.

Ergonomic Comfort & Secure Fit

Designed using multiple auricle data sets, the lightweight body and ear-wrap fit ensure a comfortable and stable wearing experience without the risk of falling off. The soft, skin-friendly resin material, paired with environmentally friendly silicone ear tips, adapts to the ear for a secure and effortless fit, providing long-lasting comfort.

High-Purity Oxygen-Free Copper Cable & Versatile Connectivity

Planet comes standard with a black four-strand oxygen-free copper Hi-Fi braided cable, ensuring high-quality signal transmission with enhanced full-frequency clarity and detail. The gold-plated 2-pin interface (0.75-0.78mm universal) allows users to swap cables freely to suit different needs and scenarios. Additionally, the built-in high-fidelity microphone delivers clear voice capture, while the multi-functional inline remote enables seamless control over calls and music playback.

34 DD approved
Color: Dark Beige, Size: 34DD
This is the first wired bra I’ve worn in years and also generally just my new favorite bra. I have breast hypertrophy and after 2 breast reductions and years of gravity, they’ll find a way to spill out of any cup and slip under any wire. The second I put this bra on I immediately felt weight off my back. The wires feel actually supportive instead of restrictive and my chest settled right into the cups smoothly and comfortably. As opposed to relying on padding (which makes me so sweaty), the construction and fabric do all the heavy lifting which makes me feel supported while still staying cool

SO very comfortable and supportive, but can't get the four hooks hooked in the back.
Color: Light Beige, Size: 44DD
I measured myself as described in listing and ordered 44dd based on that. The bra fits just right. It is super smooth and soft fabric and VERY comfortable! I especially like that it holds in the side boobs and the underwire does not poke out. I don't think I have ever had a bra before that actually stayed up on the sides! Maybe I have been wearing the wrong size?? I was skeptical and bought because of the free returns, but I am keep this one and one other style which is just as comfortable. THE ONLY THING WRONG AND THEREFORE 4 STARS is that I cannot hook the backs (4 hooks). The other one I bought was doable but with effort, this on I absolutely could not do and had to hook in the front and slide around. I don't know if there a fix for this but I will keep them because they are so dang comfy and supportive. And yes, they do minimize which is also wonderful for me!

Fits like a $100 bra
Color: Black, Size: 36H
I don’t know why HSIA bras are so comfortable. The underwire does not dig in. This is the third one I’ve purchased. This bra has a pretty lace pattern. I love it. Highly recommend.

Great bra!
Color: Dark Beige, Size: 38D
I have several different bras from this brand. This is a really good minimizer. It has a nice wide strap. I don’t love the clasp as it is covered in a hard material, but overall it is a good bra that you can wear all day under form fitting shirts.

Uncomfortable
Color: Light Beige, Size: 38DD
In my search for a comfortable well-fitting bra, I came across this one. Reviews were good, so I ordered one. Half way through the day, I had to take it off. This is the most uncomfortable bra ever. This one went on to the "uncomfortable pile" pretty quick Not full coverage and not supportive. Side coverage is pretty good but straps are thin and do not lift.
