  • Exceptional noise control

  • Pass-through function for seamless audio system switching

Most electrostatic headphones have great potential, but their sound performance is limited by the performance of the electrostatic amplifier. When using the Topping EHA5, you unlock the performance of the headphones and auditory details.

Noise control

The EHA5 features an impressive 146dB SNR, eliminating any audible noise. With noise levels under 35uVrms @G=L and under 80uVrms @G=H, you can enjoy clear sound.

Power output

The EHA5 reaches the astonishing a 700Vrms and 2000Vp-p output swing, greatly improved from the competition. This power allows your electrostatic headphones to reach their full potential.

12V trigger interface

The EHA5 is equipped witha 12V Trigger input interface, which can be easily linked with other devices for on/off switching, without the tedious operation of manually powering devices on and off one by one.

Pass-through function

When the EHA5 front panel is switched off, the input signal goes straight through the corresponding balanced and single-ended outputs. This is more suitable for switching between electrostatic headphones and the audio systems when the DAC has a preamp function.
