Know before you buy
The adjustable nozzle system allows you to physically fine-tune the ultra-high frequencies. By swapping or adjusting the nozzle, you can tailor the treble response to better suit your personal listening preferences.
With an impedance of 15.2 ohms and a sensitivity of 108db, these IEMs are relatively easy to drive. While they will work with most standard devices, a dedicated DAC or amplifier will help you get the most out of the planar magnetic driver's performance.
The double-sided coating increases the rigidity and responsiveness of the 14.5mm planar driver. This results in faster transient response and lower distortion, providing a cleaner, more detailed sound across the frequency range.
Yes, the Timeless II uses a standard 0.78mm 2-pin connector. This makes it easy to swap the included 4-core monocrystalline copper cable for a balanced cable or any other compatible aftermarket option.
Each earpiece weighs only 5 grams, making them quite lightweight for extended wear. The package includes multiple ear tip sizes to help you achieve a secure and comfortable seal for your specific ear shape.
No, the 7Hz Timeless II is designed strictly for high-fidelity audio playback and does not include an integrated microphone.
