The 7HZ Legacy

7HZ made global waves with several of its most popular models. IEMs such as the Salnotes Zero, Dioko, and Timeless gathered massive popularity due to their amazing price-to-performance value. 7HZ has proven itself to the worldwide audience as a trusted manufacturer of high-performance IEMs, and will continue its legacy with better innovations and stronger community engagement. 

7HZ x Crinacle: The Collaboration That Made History

The original Zero, which was made in collaboration between 7HZ and Crinacle, made history by being one of the best performing budget IEM’s in the market. Crinacle is a world renown reviewer, whose frequency graph database has changed the audio market forever. Using his prolific experience with IEM and headphone sound profiles, Crinacle has provided guidance in tuning the Zero once again to have the best tonal balance possible. The updated Zero:2 features Crinacle’s inputs in order to refine this tried-and-true model in order to take it to the next level.

More Bass, Keeping Tonal Excellence

The original Zero had one of the best-in-class tonal balance for a budget single dynamic driver IEM. However, this tonal balance also meant taming the bass, which may have been lacking for audiences wanting a more exciting sound. The Zero:2 maintains the perfect sound signature whilst adding on 3dB more in the low frequencies, which provides an engaging and powerful bass presence to bring your music to life. Bass impact and extension are markedly improved, providing more texture and tactile hits to the lows. Additionally, the midrange has a slightly improved body and warmth compared  to the original Zero. The slight warmth in the low-mids provides a fuller sound to instrument and vocal fundamental frequencies, yet still keeping the melodies clean and free from bass bleed. 

New 10mm Dynamic Driver

The improvements in the tonal characteristics of the Zero:2 were made possible thanks to a newly developed 10mm dual cavity dynamic driver. With an upgraded PU+Metal composite diaphragm, the driver is significantly more responsive, allowing faster diaphragm movement. This allows for harder hitting bass, while maintaining crispness and precision with each note. With a frequency range of 10Hz to 20kHz, the improvements in the new driver is immediately noticeable. 

Improved Custom Cable

The Zero II has been upgraded with a new high-purity oxygen-free copper cable with silver plating. Arranged in a coaxial structure, each wire is woven with 140.06 and 250.06 winding to strengthen the cable, as well as bringing about better audio transmission. The cable is removable to customize your listening experience as well as enhance the longevity of your IEM.

There were nice earbuds for the price until one of the earbuds died on me 2 weeks into using it. I suppose its like my room mate says, "You get what you pay for". Shouldn't have expected better than that with something this cheap. There's a chance that I got a bad batch, but it doesn't change the fact that it died 2 weeks into usage.

me likey, i sleep with them, quite comfy, sound quality really good for price.

Awesome for the price

Great IEM i think beat most expensive IEM , remembering the previous salnotes zero we have much of what we liked from the previous version which is good because we have a warm, detailed sound but now with slightly more bass.


7HZ x Crinacle Zero: 2

very affordable and with good sound. lightweight and easy to wear.

For this money you will not find any better IEM. Natural tuning without nasty bumps. This IEM you wear several hours without any problems. Sound: Then right amount of bass with a good treble extension. I miss only a portion of dynamics.

2-3mm from perfection

Very good impact and highs! Lows ar there also if I push it into my brain, but unfortunately it does not stay there. If only it would have 2-3 mm longer tip!

As good as it gets at this price point

Better than expected! Do recommend

I had a pair of kz zsn pro x, I was not really satisfied with them, the highs where piercing my ear.
With this pair I can listen to music at great quality for prolonged periods with 0 discomfort.
Do recommend!
