Upgraded JCALLY JM98Max Headphone Amplifier USB-C to 3.5mm Dual-Chip Decoder CS43198 Earphone Adapter Cable For iPhone Xiaomi

Please note1. This product is a high-power headphone amplifier that may generate slight heat during use, reaching approximately 38°C. This is normal and safe for operation.2. If unsure about compatibility, carefully review the image descriptions, which include detailed displays of supported smartphone/tablet/laptop models.3.If there is no audio input for a few seconds, the device will automatically enter standby mode (red light turns on). This is a standard design feature intended to reduce heat generation and extend the lifespan of the DAC chip during prolonged use while plugged in.4.Due to the nature of the USB adapter, Windows systems will, by default, cut off power to the USB port after a period of inactivity. Once the DAC enters low-power standby mode, the system determines that the device is not in use and immediately disconnects the USB connection. This results in the device disappearing from the sound settings and requiring a reinsertion—a phenomenon unrelated to hardware quality.Package Contents1×JM98 MAX Headphone Amplifier1×USB Interface1×User ManualParametersModel: JCALLY JM98 MAXDAC Chip: CS43198Op-amp Chip: SGM8262PCM Sampling Rate: 32-bit/384kHzDSD Sampling Rate: DSD256Signal-to-Noise Ratio: ≈125dBDistortion: ≈0.0003%Output Power: ≈195mWOutput Impedance: ≈0.65ΩDimensions: Approximately 11cmEQ Adjustment Indicator Lights:Original Sound: YellowBass Boost: CyanTreble Boost: PinkSample Format Indicator Lights:Standby: RedPCM: GreenDSD (Exclusive): BlueFunction Support:Supports music, gaming, live streaming, calls, recording, inline controls, three-band EQ switchingUAC 1.0 and 2.0 mode switchingCompatibility:Supports Android/iOS devices with Type-C ports, tablets, and computers running MAC/Windows 10 or later; compatible with Switch, PS5 consoles, and Windows 7 computers (requires switching to UAC 1.0 mode)Cable Material:8-strand silver-copper hybrid 448-core, silver-plated conductorsHousing Material:Aluminum alloy CNC-machined curved surface, tempered glass CNC curved edge finishHigh-concerned chemical : NoneSignal To Noise Ratio : 125dbBody Material : MetalWIFI : NoBluetooth : NoPCM : YesDSD (Direct Stream Digital) : YesOperational Amplifier Chips Model : SGM8262DAC Model : CS43198Channels : 1Package : YesModel Number : JM98 MAXType : Mini AmplifierRecommended Headphone Maximum Impedance : 32 - 50 OhmBuilt-in Battery : NoOutput Type : LINE OUT (AUDIO OUT)Input Type : USB,LINE IN (AUDIO IN)Brand Name : WAPUNOOrigin : Mainland China
