The Fosi Audio PH05 is a one-in, five-out headphone amplifier and splitter: each 3.5mm output has its own volume knob and delivers up to 310mW into 32Ω, with a master volume and one-touch mute on top. It suits podcasts, studios, classrooms and shared TV listening where several people need their own volume from one source.
Who the Fosi Audio PH05 is for
Podcast and studio monitoring: Hosts and guests each set their own level from a single feed, with a rated 105dB SNR and 0.001% THD.
Classrooms and family TV: Up to five headphones can share a tablet, computer or TV through the 3.5mm AUX input, each at its own volume.
Comparing headphones: Every channel drives 16–300Ω headphones and IEMs, so different models can be set to matching loudness side by side.
Quick muting: The one-touch mute button silences the output, and the indicator turns blue while muted.
Skip it if: You need more than one input, a microphone path for calls, or 6.35mm jacks; the PH05 has one 3.5mm input and five 3.5mm outputs.
Build and size: All-aluminum alloy with anti-slip feet; 103 × 57 × 43 mm
In the box: PH05 amplifier, 3.5mm aux cable, power supply, user manual
