ddHiFi DustCap35 Gem – Premium Titanium Alloy 3.5mm Dust Cover with Zircon Decoration for Audiophile Players and DAC/AMP Devices The ddHiFi DustCap35 Gem is the jeweled edition of ddHiFi's precision-engineered 3.5mm headphone port dust cover, combining the full functional performance of the DustCap35 with an elegant synthetic zircon decorative stone set into the top of the cap. Designed for audiophiles who want to protect the 3.5mm headphone jack on their digital audio players and DAC/AMP devices while adding a touch of refined visual distinction to their setup, the DustCap35 Gem is the perfect finishing detail for a premium portable audio collection. Headphone jacks on professional audio players frequently go unused for extended periods - leaving exposed sockets vulnerable to dust accumulation and oxidation that degrades contact quality over time. The DustCap35 Gem keeps idle 3.5mm ports permanently sealed, protected, and looking exceptional. The synthetic zircon gem inlaid at the top of the DustCap35 Gem is crafted from synthetic zirconium oxide - not a natural diamond, but a material that is significantly harder than ordinary glass and delivers a brilliant, diamond-like visual sparkle. This decorative stone serves a purely aesthetic purpose, adding a distinctive premium touch that sets the Gem Edition apart from the Standard Edition while adding just 0.1g of additional weight. The gem is securely set into the precision-machined titanium alloy body, ensuring it remains firmly in place through daily insertion and removal without risk of loosening. The core functional performance of the DustCap35 Gem is identical to the Standard Edition. The brushed titanium alloy body is machined with an insertion length precisely matched to the grounding section of the 3.5mm socket. When inserted, the titanium body makes contact with the socket's grounding spring clip, providing genuine anti-interference and EMI grounding shielding that actively reduces background noise from the player's internal electronics - a functional advantage that distinguishes the DustCap35 from ordinary plastic dust covers. Most headphone jacks on professional audio players use plastic socket housings that offer no shielding when the port is idle, making the DustCap35 Gem both a protective and a performance-oriented accessory. The distinctive hourglass-shaped body with its smooth brushed titanium alloy finish sits flush and elegantly on any device, with the sparkling zircon stone catching the light and drawing the eye. With dimensions of 8.0mm height and Ø4.45mm at the widest point, and a weight of just 1.6g per piece, the DustCap35 Gem is an indispensable and beautiful finishing touch for any serious audiophile's portable setup. Compatible with all standard 3.5mm TRS and TRRS headphone sockets on players from Astell&Kern, FiiO, iBasso, Shanling, Lotoo, HiBy, and many other premium HiFi brands.
