7Hz x Crinacle Zero:2 (Salnotes Zero 2) Dynamic Driver IEM – Orange

Enjoy a fuller, more engaging take on the popular Salnotes Zero tuning with the 7Hz x Crinacle Zero:2 (Salnotes Zero 2) Dynamic Driver IEM – Orange.

Developed in collaboration with Crinacle, the Zero:2 uses an upgraded 10mm dual-cavity dynamic driver with a PU + metal composite diaphragm. Compared with the original Salnotes Zero, the Zero:2 adds approximately 3dB more low-frequency energy, giving bass more depth and impact while adding extra warmth to the lower midrange.

The Zero:2 also features a detachable 0.78mm 2-pin connection and an upgraded silver-plated high-purity oxygen-free copper cable. The Orange finish is an official Zero:2 color option alongside Silver, Blue, and Pink.

Specifications

The published Zero:2 specifications confirm a 10mm dynamic driver, 32Ω impedance, 10Hz–20kHz response, <1% THD at 1kHz, and detachable 0.78mm 2-pin connection.

Tuned in Collaboration with Crinacle

The Zero:2 builds on the tuning approach that made the original Salnotes Zero popular in the entry-level IEM market.

For the second generation, 7Hz and Crinacle retained the balanced foundation while adding more low-frequency presence and slightly more warmth.

The resulting sound is designed around:

• Stronger Bass
• Clear Vocals
• Natural Midrange
• Controlled Treble
• Good Tonal Balance
• More Engaging Overall Presentation

This makes the Zero:2 a strong all-round option for users who found the original Zero slightly too lean.

Upgraded 10mm Dual-Cavity Dynamic Driver

The Zero:2 uses a newly developed 10mm dual-cavity dynamic driver.

Its PU + metal composite diaphragm is designed to respond faster, helping the driver produce harder-hitting low frequencies while maintaining clean note definition.

This benefits:

• Bass Impact
• Bass Extension
• Drum Attacks
• Instrument Definition
• Vocal Clarity
• Game Sound Effects
• Fast Music Passages

Approximately 3dB More Bass

One of the biggest differences between the Zero:2 and the original Zero is the bass response.

The Zero:2 adds around 3dB of additional low-frequency gain, giving bass more impact and extension.

This makes the Orange Zero:2 especially enjoyable for:

• Hip-Hop
• Electronic
• Pop
• R&B
• Rock
• Movie Soundtracks
• Racing Games
• Action Games
• Cinematic Gaming

The additional bass gives explosions, engines, drums, and electronic bass lines more weight than the original Zero.

Fuller & Warmer Midrange

The updated tuning also adds some warmth to the lower midrange.

This gives additional body to:

• Male Vocals
• Female Vocals
• Guitar
• Piano
• Drums
• Acoustic Instruments
• Game Dialogue

The goal is a fuller presentation without allowing the extra bass to overwhelm the midrange.

Balanced Sound for Everyday Listening

Despite the added low-end presence, the Zero:2 is not intended to be an extreme bass-focused IEM.

Its overall tuning remains balanced enough for users who listen to several different genres rather than buying a separate earphone for every style of music.

This makes it a practical daily IEM for:

• Music
• Gaming
• Movies
• Streaming
• Podcasts
• YouTube
• Portable Listening

10Hz–20kHz Frequency Response

The Zero:2 has a rated frequency-response range of:

10Hz – 20,000Hz.

The extended low-frequency specification complements the Zero:2's stronger bass tuning while the upper end covers the standard audible treble range.

32Ω Impedance

The Zero:2 has a rated impedance of 32 ohms.

It can be used with many compatible sources, including:

• Smartphones with Headphone Output
• USB-C DAC Dongles
• Laptops
• Desktop PCs
• Gaming Handhelds
• Portable DACs
• Digital Audio Players
• Compatible Game Controllers

Because its published sensitivity is 108dB/V, very low-output devices may provide less volume headroom than some highly sensitive IEMs. A good USB DAC/dongle can be useful when the source device has a weak headphone output.

Detachable 0.78mm 2-Pin Connection

The Zero:2 uses a 0.78mm 2-pin detachable cable interface, one of the most common connection standards used by enthusiast IEMs.

A detachable cable provides several advantages:

• Easier Cable Replacement
• Longer IEM Service Life
• Aftermarket Cable Options
• Microphone Cable Options
• Different Plug Options
• Easier Repair if the Cable Is Damaged

The IEM itself does not need to be replaced simply because the cable wears out.

Upgraded Silver-Plated OFC Cable

The Zero:2 receives an upgraded stock cable made from high-purity oxygen-free copper with silver plating and a coaxial construction.

The detachable cable complements the IEM's affordable enthusiast-focused design and gives owners flexibility for future upgrades.

Available in 3.5mm & USB Type-C Versions

The Zero:2 is currently offered in several configurations:

• 3.5mm – No Microphone
• 3.5mm – With Microphone
• USB Type-C – With Microphone

For ecommerce accuracy, the connection type should match the exact stock being sold.

If your Orange stock is the standard 3.5mm no-microphone version, it should be listed as an audio-only IEM without an inline microphone.

Multiple Silicone Ear Tips

A typical Zero:2 retail package includes six pairs of silicone ear tips in multiple sizes, allowing users to experiment with fit and seal.

Finding the correct ear-tip size is important because the seal affects:

• Bass Response
• Passive Isolation
• Comfort
• Stability
• Overall Sound Balance

If an IEM sounds unusually thin or lacks bass, trying a different ear-tip size can often improve the seal.

Passive Noise Isolation

The Zero:2 does not use electronic Active Noise Cancellation.

Instead, it relies on the physical seal of the ear tips.

A good fit can help reduce surrounding distractions while:

• Gaming
• Listening at Home
• Commuting
• Working
• Studying
• Traveling

Passive isolation requires no extra electronics or batteries.

Excellent for Music

The Zero:2's added bass and balanced tonal profile make it suitable for a wide variety of genres.

Great for:

• Pop
• Hip-Hop
• Electronic
• Rock
• R&B
• Jazz
• Classical
• Acoustic
• Metal
• Soundtracks

The stronger low-frequency presentation gives modern music more energy while keeping vocals clearly represented.

Great for Competitive Gaming

IEMs have become popular among PC and console gamers because of their lightweight design and direct in-ear fit.

The Zero:2 can reproduce gaming cues such as:

• Enemy Footsteps
• Reload Sounds
• Gunfire
• Vehicle Movement
• Environmental Effects
• Dialogue
• Directional Audio Information

Its balanced sound makes it useful for players who want gaming detail without sacrificing enjoyable music reproduction.

Great for FPS Games

The Zero:2 is suitable for games such as:

• Counter-Strike 2
• VALORANT
• Call of Duty
• Fortnite
• Apex Legends
• PUBG
• Rainbow Six Siege
• Battlefield
• Overwatch

The wired design also avoids the Bluetooth latency that can affect some wireless earbuds.

Great for Racing Games

The increased bass response can add impact to:

• Engine Notes
• Gear Changes
• Tire Noise
• Collisions
• Track Atmosphere

This makes the Zero:2 well suited to:

• Gran Turismo
• Forza
• F1
• Need for Speed
• Assetto Corsa
• EA Sports WRC

Great for Single-Player Gaming

The stronger low end also benefits cinematic games.

Ideal for:

• RPGs
• Action Games
• Horror Games
• Open-World Titles
• Story-Driven Games
• Adventure Games

Soundtracks and cinematic effects gain additional weight compared with the leaner original Zero.

Great for Gaming Handhelds

The compact wired IEM format is useful with compatible handheld gaming devices.

Potential applications include:

• Steam Deck
• ASUS ROG Ally
• Lenovo Legion Go
• Gaming Laptops
• Portable PCs
• Nintendo Systems with Compatible Audio Output

There is no headset battery to worry about during long portable gaming sessions.

Lightweight Alternative to Gaming Headsets

Traditional over-ear gaming headsets can become warm or heavy over long periods.

The Zero:2 offers a much smaller alternative.

Advantages include:

• No Headband Pressure
• No Large Earcups
• Compact Storage
• Lightweight Design
• Easy Travel
• Wired Low-Latency Audio

Players who do not need a boom microphone may prefer an IEM for extended gaming.

No Battery Required

Because the Zero:2 is wired, it requires:

• No Charging
• No Bluetooth Pairing
• No Battery Maintenance
• No Wireless Dongle
• No Codec Setup

Connect it to a compatible source and start listening.

Official Orange Color

Orange is one of the official color choices for the 7Hz x Crinacle Zero:2, alongside Silver, Blue, and Pink on the current Linsoul product listing.

The Orange version is ideal for users looking for something more distinctive than a traditional Black or Silver IEM.

It works especially well with:

• Orange Gaming Setups
• RGB Gaming Desks
• Gaming Handhelds
• Portable DACs
• Colorful PC Setups
• Custom Gaming Accessories

• 1 × Detachable 0.78mm 2-Pin Cable
• 6 Pairs of Silicone Ear Tips in Assorted Sizes

Important: The Zero:2 is sold in multiple connection configurations. Current official retail options include 3.5mm without microphone, 3.5mm with microphone, and USB Type-C with microphone. The ecommerce specification should therefore be matched to the exact version physically supplied in your stock.

Gaming Note: If your Orange unit is the standard 3.5mm no-microphone version, it provides game audio but does not include a microphone for voice chat. A separate microphone or compatible microphone-equipped replacement cable is required.

Compatibility Note: Devices without a suitable 3.5mm headphone output require an appropriate USB-C, Lightning, or other audio adapter/DAC depending on the device. The Type-C cable version is sold as a separate configuration and should not be assumed to be included with a 3.5mm unit.
