Portable 3.5 mm Headphone Amp

The Vszerda portable headphone amplifier connects between a 3.5 mm source and wired headphones to boost volume and clarity. It is aimed at listeners who want louder, cleaner output from phones, tablets, computers or consoles without a desktop-sized unit.

Replaces weak built-in outputs

It steps in when a device’s own headphone jack cannot drive high-impedance models in the 16-300 ohm range or introduces audible hiss. The two-stage gain switch lets you match the amplifier’s input level to the source so the jump is worthwhile whenever the stock output sounds thin, noisy or simply too quiet.

Plug in, switch on, adjust volume

Installation is a single 3.5 mm cable from source to amp and another from amp to headphones; the 1000 mAh battery runs for 12-15 hours per charge. The main pitfall is using the unit while charging — current disturbance can add noise — so plan charge cycles around listening sessions.
