Key Features

【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.
【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. 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.
【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.
【𝐈𝐦𝐩𝐫𝐨𝐯𝐞𝐝 𝐂𝐮𝐬𝐭𝐨𝐦 𝐂𝐚𝐛𝐥𝐞】The Zero:2 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.
