⚠️ Production & Quality Control Disclosures

To ensure total transparency and the absolute best connection setup, please review these key hardware compatibility facts before selecting your model:

• 📊 Critical Hardware Interface Selection: This series features two separate physical connector variants—a standard 3.5mm round audio port and a digital Type-C port. Please carefully verify your smartphone, tablet, or laptop connection port prior to checking out.

• 📲 Type-C System Compatibility Exceptions: Due to proprietary manufacturer audio firmware, the Type-C variant model is not compatible with the following device lines: Huawei (Mate 50/P60 series), Samsung (S20/S21/S22/S23, Note 10, A60, A90), Meizu (All), OnePlus (8/8T), Honor (70/MagicVS), Xiaomi (12s, Redmi Note 11 Pro+), HTCu11, iPad Pro, and iPad Mini. For these specific devices, please utilize the 3.5mm variant combined with your device's official adapter.

• 🔌 Lightning Interface Workaround Limits: If you are using a device with a legacy Lightning port, you can pair the 3.5mm headphone variant with an external 3.5mm-to-Lightning adapter. Please note that standard third-party adapters will pass stereo music playback but do not support inline microphone recording functions.

💡 Pro-Tip for Elite Karaoke Recording Optimization: To achieve a flawless, studio-grade vocal mix on karaoke apps, ensure the earbuds are firmly seated in your ear canal to activate the alloy sound-lock seal. Hold the inline microphone roughly 2 to 3 inches away from your mouth while singing to prevent breath clipping, allowing the high-sensitivity capsule to capture a clean, uncompressed vocal layout!
