NICEHCK Himalaya In-Ear Earphones, 1DD, 10mm Dynamic Driver, Re-cableable, Pure Titanium Alloy Housing, 2.5mm, 3.5mm, 4.4mm Interchangeable Plugs,

[Pure Titanium Alloy Cavity] Himalaya earphones feature a pure titanium alloy cavity, processed with 5-axis CNC machining for a high-quality appearance. This effectively reduces cavity resonance and suppresses harmonic generation, improving sound quality. Titanium alloy material has excellent corrosion resistance and hardness, making it resistant to oxidation, rust, deformation, and cracking. However, it may be prone to scratches from friction with the packaging, sweat, fingerprints, and other marks. If such marks are present, simply wipe them with a soft, dry cloth. This will remove them. [Carbon Nano Dynamic Driver] Himalaya earphones are equipped with a dual magnetic double-layer carbon nano dynamic driver. Its flagship design includes front and rear dual cavities, a coaxial double-layer diaphragm, and a dual magnetic circuit system, resulting in rich, powerful bass, smooth, natural, and durable treble, natural and smooth transitions across three frequencies, and delicate vocals. [Interchangeable Acoustic Filters] Himalaya earphones come with three different filter styles to suit your tastes and music genres. The standard gold filter provides a balanced and smooth sound; the blue filter enhances the low frequencies for a more passionate sound; and the gray filter delivers stunning high-frequency detail and clarity, allowing audiophiles to choose their own preferences. [Interchangeable Plugs, Enjoy HIFI Sound Quality] Himalaya earphones come with a silver-plated oxygen-free copper cable, which provides excellent signal transmission and easy handling. They also come with interchangeable plugs (2.5mm balanced, 3.5mm, and 4.4mm balanced) for a variety of connections. Ergonomically designed, they fit snugly in your ears for a more comfortable fit and a pleasant listening experience. To ensure proper earphone use, please refer to the image below for the correct installation of the interchangeable plugs. If the interchangeable plugs are not installed correctly, one earphone may not produce sound or the sound may be different between the two. If you encounter this issue, please first check that the plugs are installed correctly. [One-year warranty] The warranty period for non-human-caused quality issues is one year from the date of purchase.
