Watch this official video from Linsoul Audio for a quick overview of the 7Hz x Crinacle Zero:2 In-Ear Monitor and its components.

The Zero:2 features a detachable 2-pin cable. Carefully align the pins on the cable with the receptacles on each IEM unit. Gently push until the cable is securely connected. Ensure the correct orientation (left and right) for optimal sound staging.

Choose the ear tips that provide the best seal and comfort for your ears. A proper seal is crucial for bass response and sound isolation. Gently push the selected ear tip onto the nozzle of the IEM until it is firmly seated. Different sizes and colors are provided to help you find the perfect fit.

Insert the IEMs into your ear canals. The cable is designed to loop over your ear for a secure and comfortable fit, reducing microphonics (cable noise). Adjust the cable over your ear until it feels stable and the IEMs are snug in your ears.

Connect the 3.5mm jack of the IEM cable to your audio source (smartphone, digital audio player, computer, etc.). Ensure the connection is secure. The IEMs are now ready for use.

Once connected, begin playing audio from your device. Adjust the volume to a comfortable listening level. The 7Hz x Crinacle Zero:2 IEMs are known for their balanced sound signature with enhanced bass, clear mids, and detailed highs, providing an immersive listening experience across various music genres. For optimal sound, ensure your audio files are of high quality.
These IEMs are compatible with any device featuring a standard 3.5mm audio jack. They are suitable for music listening, gaming, and studio monitoring, offering versatile use across different platforms.
