Introduction
The 7Hz G1 is a recent addition to the ChiFi world, launched with a clear focus on gamers, audiophiles, and casual music lovers alike. Equipped with a 10mm dual magnetic dynamic driver, DLC (Diamond-Like Carbon) diaphragm, and powerful N52 magnets, this IEM offers a sound profile that is rich, immersive, and technically impressive.
Priced at ₹3190 in India, the G1 has been my daily driver since January—and honestly, I'm in love with it. The sad part? No one seems to be talking about it. In a world flooded with countless new ChiFi IEMs, the G1 risks being lost in the noise. But I genuinely believe it deserves attention, and through The Audio Store platform, I want to shine a light on this underrated gem.
This review is not just technical—it’s personal. Today, I’ll share why I’ve been using the 7Hz G1 every day, and why it might just be the next IEM you fall in love with.
Design and Build Quality
The 7Hz G1 IEM a two-piece metal shell that feels solid and well-crafted in the hand. The build quality inspires confidence—it’s reliable, durable, and ready for daily use. The cable is simple but practical, ideal for casual wear, though not flashy.
You get a decent carry case and stock silicone eartips that are surprisingly good in terms of comfort and isolation. The overall aesthetic is minimal: a matte black finish with a subtle golden 7Hz logo on the faceplate. While not designed to turn heads, it’s a look that blends well with daily usage—understated, functional, and classy in its own way.
Comfort and Fit
The G1 shell is medium-sized, and for my ears, the fit is nearly perfect. I’ve worn it for 3-4 hours at a stretch without experiencing any discomfort or fatigue.
With the stock eartips, I get a snug fit, excellent noise isolation, and consistent sound. The nozzle goes deeper into the ear canal, which may not work for everyone, but for me, it ensures a secure seal and better bass response.
Sound Quality
My Testing Setup:
Most of the time, I’ve paired the 7Hz G1 with an iPhone 12 using Apple’s Lightning to 3.5mm dongle for music and calls—both indoors and outdoors. Occasionally, I tested it with HiBy R4, HiBy R8 II, Questyle M15, and MacBook Air. What I found fascinating is how well the G1 scales with better sources.
Many budget IEMs hit a plateau in sound quality, but the G1 keeps surprising me. I even know seasoned audiophiles who’ve used it with high-end DAPs like the Shanling M8T, and they were genuinely impressed.
Sound Overview:
The 7Hz G1 delivers a smooth, rich, detailed, and clean sound with impressive layering and texture. The tonality feels natural and musical. It has a mild V-shaped tuning that leans into emotional bass, engaging mids, and a musical treble.
🎧 Sound Signature: Mild V-shaped
🔊 Bass: Punchy & deep
🎙 Midrange: Textured & emotional
🎼 Treble: Clean, airy & smooth
🌌 Soundstage: Wide with decent depth
Let’s break it down further:
Bass
The bass on the G1 is deep, rich, full-bodied, and punchy—just the way I like it. Sub-bass is head-filling but never intrusive; it doesn’t bleed into the mids. The bass maintains a controlled presence without being overly boosted. It’s a pleasant, musical bass that complements almost every genre I’ve thrown at it.
Midrange
Vocals are where the G1 truly shines. Male and female vocals sound natural and textured, with no harshness or sibilance. Sometimes I do feel that midrange instruments—especially in busy tracks—don’t get as much weight. But for this price point, the vocal performance is stellar, and the overall presentation is clean and honest.
Treble
The treble performance is detailed, clean, and musical. Instruments like cymbals, violins, piccolos, veenas, and Santoors sound beautiful—airy, but not sharp or fatiguing. There’s a sense of refinement and clarity here that’s hard to find in this price bracket. It’s the kind of tuning that keeps you immersed without tiring your ears.
Soundstage & Imaging
The soundstage on the G1 is wide and has good vertical height, which gives your music space to breathe. Imaging is average—not pinpoint accurate like some higher-end IEMs—but layering is well executed for its class.
Value and Competition
In the ₹3000 segment, I currently own the Kinera Celest Wyvern Abyss and BLON BL03 II, and I’ve compared them directly with the 7Hz G1.
