Choose the Correct Impedance Option: -

Ry4S earbuds are available in two different variants, the 32Ω version and the 300Ω version. The 300Ω variant is ideal for dedicated audio equipment with headphone amplifiers in the chain while the 32Ω variant is suitable for regular devices such as smartphones. 300Ω earphones usually sound cleaner and have reduced distortion but they require special equipment. A headphone amplifier is required to get the best output quality from these 300Ω earphones. 32Ω earphones provide excellent sound without the need of such amplification.

  • 300 OHM IMPEDANCE: The earbuds have a 300 Ohm impedance, ideal for dedicated audio equipment like headphone amplifiers. These devices provide the power needed for clear signals, reduced distortion, and accurate sound. Keep in mind that higher impedance earphones may not work optimally with low-power devices like smartphones. A headphone amplifier might be necessary to fully drive the earphones and unlock their potential.
  • 32 OHMS IMPEDANCE: The earbuds have an impedance of 32 Ohms. This level of impedance makes earbuds suitable for use with a wide range of devices, including smartphones, laptops, and portable audio players, without requiring additional amplification. They can provide good sound quality and volume directly from these devices without the need for additional equipment.

15MM DYNAMIC DRIVER: The earbuds have a 15mm dynamic driver with a larger diaphragm for improved bass response, resulting in deeper and more impactful low-frequency sounds. This larger diaphragm also enhances overall sound clarity and detail across different frequencies, providing a more immersive listening experience by revealing subtle elements in the music that might be missed with smaller drivers.

MMCX EARBUDS WITH UNIVERSAL 3.5MM JACK: These earbuds feature an MMCX connector, allowing the cable to be easily detached and replaced. The included cable has a 3.5mm jack, making it compatible with a wide range of devices such as smartphones, music players, and laptops. This design offers versatility and the option to customize or replace cables when needed.

HIGH PURITY DETACHABLE CABLE: These earbuds come with a cable that can be easily detached from the earbuds. This feature allows for convenient cable replacement, customization. It also provides flexibility to switch between different cables for various purposes, such as using longer or shorter cables, upgrading to HIFI cables, or replacing a damaged cable.

BRADED LITZ STRUCTURE CABLE: The cable uses a litz structure winding technique, which involves twisting multiple thin strands of copper wire together. This Provides better signal transmission.

CHIN SLIDER: The cable is equipped with a chin slider, which allows you to adjust the length of the cable and secure it in place for a more comfortable listening experience.

ERGONOMIC DESIGN & LIGHTWEIGHT: The lightweight and ergonomic design ensure that the earphones won't cause discomfort to your ears, even after wearing them for a long period of time. They are lightweight and won't put any strain on your ear.
