16-300Ω HiFi Headphone Amplifier Mini Audio Amplifier HiFi Stereo Earphone Amp Audio Amp With 3.5mm Jack Cable For Music Player
Product Description
Unlock the audio potential of demanding headphones and low-output media players with this ultra-portable HiFi headphone amplifier. Built for music lovers and mobile audiophiles, this rechargeable amplifier fills the power gap between smartphone or DAC outputs and power-hungry full-size headphones or high-impedance In-Ear Monitors (IEMs).
Housed in a lightweight aluminum alloy shell that blocks electromagnetic interference, the amplifier comes with an integrated rotary power switch and volume dial. It uses a distortion operational amplifier circuit to boost audio signal levels while keeping sound clean and clear (SNR > 100 dB). With its lasting internal lithium battery, included 3.5 mm auxiliary patch cable, and universal plug-and-play setup, it’s a simple, convenient solution for better sound on commutes, flights, or desktop use.
Key Features
Low-Distortion HiFi Circuitry: The analog signal path is carefully designed for performance. It achieves a signal-to-noise ratio ($\text{SNR} > 100\text{dB}$) and keeps distortion extremely low at $\text{THD+N} < 0.0003\%$. The result is clean audio with almost no background noise.
Two-Stage Gain Control Switch: A physical gain switch lets you adjust output levels manually.
This makes it easy to match the amplifier to low-sensitivity headphones or high-sensitivity IEMs. The switch changes gain without adding noise or changing the quality.
Aluminum Alloy Matte Shielding Housing: The housing is made of heavy-duty aluminum alloy.
It protects the parts, helps with heat dissipation, and blocks RF and EMI interference from nearby devices, like smartphones. This keeps the signal clean and stable.
