Introduction:
7Hz, is already a known name in the audiophile world, hails from China. They've quickly gained a reputation for producing IEMs that offer exceptional value for money, often punching well above their weight class. Personally, I've been thoroughly impressed with their previous releases, especially the Zero, Zero 2, and Timeless – each offering a unique flavor of sonic excellence.
Now, 7Hz is back with the G1, a single dynamic driver IEM that promises to deliver a captivating listening experience at an incredibly accessible price point. Let's dive into the specifics and see if it lives up to the hype.

Unboxing Experience:
The unboxing experience is simple but satisfying. The G1s arrive in a compact box containing the IEMs themselves, a selection of silicone ear tips, a 0.78mm 2-pin
cable and a round silicone carry case. While there are no extravagant extras, the presentation is clean and efficient, reflecting the G1's focus on delivering core value.
I love the fact that 7Hz included a carry case at this price. While the silicone case is not going to protect the IEMs from any impact, it does protect them frrom other things in your bag.
Design and Build:
The IEMs themselves sport a sleek, understated design. The black metal shells (I'm assuming aluminium) are ergonomically shaped and feel comfortable in the ear. They look and feel like small pebbles to be honest. The included cable is decent that minimizes tangling and feels durable enough for everyday use. While not as luxurious as some high-end cables, it's perfectly functional and complements the G1's aesthetic.
Wearing Comfort:
The G1s are designed for long listening sessions. The lightweight shells and ergonomic shape ensure a comfortable and secure fit. I was able to wear them for hours on end without any discomfort. A point to note is that that the nozzle length was on the shorter side due to which I had to use tips with longer nozzles. The angle of the nozzle however was well-judged, allowing for a good seal and effective passive noise isolation.
Sound Analysis:
Tonality:
Imagine a warm, inviting living room bathed in the soft glow of a fireplace. That's the kind of warmth the G1s bring to your music. It's a gentle, comforting presence that enhances the listening experience without adding any artificial coloration.
Sub Bass:
The sub-bass plunges into the depths of the music, providing a solid foundation for tracks with a powerful low-end presence. In "Why So Serious?" from the Dark Knight soundtrack, the ominous rumble sends shivers down your spine, while the deep, resonant bassline in "Royals" by Lorde adds a visceral dimension to the track. However, the decay is a touch too quick, preventing the sub-bass from fully blooming and lingering in the air.
Mid-bass:
This is where the G1 truly comes alive. The mid-bass is a masterclass in balance, delivering impact and texture in equal measure. In "Seven Nation Army" by The White Stripes, the iconic bassline hits with a satisfying thump, while the intricate bass work in "Feel Good Inc." by Gorillaz grooves with infectious energy. Each note is defined and articulate, contributing to a rhythmically engaging experience.
Lower Midrange:
Male vocals are enveloped in a warm embrace, adding a sense of intimacy and richness. Leonard Cohen's baritone in "Hallelujah" resonates with emotion and gravitas, while the smooth vocals of Frank Sinatra in "Fly Me to the Moon" are rendered with a velvety smoothness. Female vocals are equally well-served, with a touch of warmth that enhances their presence without sacrificing clarity. However, a slight dip in the lower midrange can sometimes make instruments like cellos and baritone saxophones feel slightly less present in the mix.
Upper Midrange:
This region sparkles with clarity and detail. Vocals, both male and female, are presented with exceptional precision, allowing you to hear every nuance and inflection. In "Hotel California" by the Eagles, the harmonies are beautifully layered, each voice distinct and clear. Instruments like violins and trumpets shine in this region, their timbres rendered with accuracy and vibrancy.
Lower Treble:
The lower treble is where the G1 adds a touch of sparkle and airiness to the music. It's not overly emphasized, but it's present enough to give cymbals a delicate shimmer and hi-hats a crisp attack. Listening to "Little Wing" by Jimi Hendrix, the guitar notes had a beautiful sheen without ever becoming harsh or sibilant. This was particularly noticeable when I paired the G1s with the iBasso DX320, which has a slightly brighter treble presentation.
Upper Treble:
The upper treble, however, is where the G1 shows some restraint. It rolls off gently, which helps to tame sibilance and prevent fatigue during long listening sessions. However, this can also result in a slight loss of air and brilliance in tracks with a lot of high-frequency energy. In "Dreams" by Fleetwood Mac, the shimmering cymbal crashes lacked some of their ethereal quality.
Soundstage:
Imagine yourself in a concert hall, surrounded by musicians. That's the kind of experience the G1s create. The soundstage extends beyond the confines of your head, with a sense of depth and height that adds to the immersion. In "Comfortably Numb" by Pink Floyd, the guitars seem to emanate from different points in space, enveloping you in a sonic tapestry.
Layering and Separation:
Even in the most complex musical passages, the G1s effortlessly separate individual instruments and vocals. In orchestral pieces like Beethoven's Symphony No. 5, the various sections of the orchestra are clearly delineated, allowing you to appreciate the interplay between the different instruments.
Timbre:
Instruments and voices have a natural and realistic quality. The acoustic guitar in "Tears in Heaven" by Eric Clapton resonates with a woody warmth, while the vocals in "Hallelujah" by Jeff Buckley are infused with raw emotion. The G1s capture the essence of each instrument and voice, bringing the music to life.
Detail Retrieval:
While not as resolving as high-end IEMs, the G1s punch well above their weight in terms of detail retrieval. They unveil subtle nuances in the music that might otherwise go unnoticed. In "Clair de Lune" by Debussy, the delicate intricacies of the piano performance are rendered with impressive clarity, allowing you to appreciate the subtle interplay of notes.
Comparisons:
7Hz Salnotes Zero 2 vs 7Hz G1: The Zero 2, another excellent offering from 7Hz, has a brighter sound signature with a more pronounced treble presence. The G1, in comparison, is warmer and smoother, with a more relaxed treble presentation. Both IEMs offer excellent detail retrieval and a spacious soundstage, but the G1 has a slight edge in terms of bass impact and overall coherence.
Kinera Celest Wyvern Black vs 7Hz G1: The Wyvern Black has a more balanced sound signature compared to G1 with a slight emphasis on the midrange. It excels at vocal clarity and instrumental separation. The G1, while also balanced, has a warmer tilt and a more impactful bass response. The Wyvern Black might be a better choice for those who prioritize vocal-centric music, while the G1 offers a more engaging and dynamic listening experience.
Kiwi Ears Cadenza vs 7Hz G1: The Cadenza is known for its energetic and vibrant sound signature, with a V-shaped frequency response that emphasizes the bass and treble. The G1, in comparison, is more balanced and refined, with a smoother treble and a more controlled bass response. The Cadenza might appeal to those who prefer a more exciting and impactful sound, while the G1 offers a more nuanced and mature presentation.
Tripowin x 0DiBi Vivace vs 7Hz G1: The Vivace has a warmer and smoother sound signature than the G1, with a thicker note weight and a more relaxed treble. The G1, in comparison, has a slightly brighter tilt and a more agile presentation. Both IEMs offer excellent value for money, but the G1 has a slight edge in terms of technical performance and overall refinement.
Conclusion:
The 7Hz G1 is a testament to the fact that audiophile-grade sound doesn't have to break the bank. They deliver a captivating listening experience that's rich in detail, dynamics, and musicality. While minor shortcomings exist, the G1's strengths far outweigh its weaknesses, making it a true gem in the budget IEM category. Whether you're a seasoned audiophile or just starting your journey into the world of high-fidelity sound, the 7Hz G1 is a compelling option that deserves your attention. It's a reminder that sonic excellence can be found in the most unexpected places, and that sometimes, the most satisfying discoveries are the ones that defy expectations.
"Transcending the usual Harman sidegrade hoards, the G1's calling card is its imaging and layering, and is well-suited for our gaming brethren."
Great review!
