Act as a senior wearable tech designer with 10+ years of experience in minimalist hardware. Create a photorealistic product render of a premium smart tie clip with integrated microphone for professionals. The design should feature [MATERIAL: brushed titanium], [COLOR SCHEME: gunmetal with navy blue accents], and [ADDITIONAL FEATURES: wireless charging compatibility]. Show the clip in a business setting, subtly blending with a silk tie while maintaining clear visibility of the discreet microphone port. Include precise details like the tactile button placement, LED status indicator, and the clip's tension mechanism. The product should appear both elegant and functional, with proper lighting to highlight the [SURFACE TEXTURE: fine linear brushing] and [LOGO PLACEMENT: embossed on the side]. Render at 8K resolution with a shallow depth of field.
