TRENDnet TK-409K 4-Port USB KVM Switch Kit with Audio Review
The TRENDnet TK-409K is the audio-equipped version of the TK-407K, a 4-port USB KVM switch that also shares a microphone and speaker set across four VGA computers.
Everything else matches the 407K: front-panel button, keyboard hotkey, or Windows-based software switching, USB-powered operation, and VGA resolution up to 2048x1536. The difference is the added 3.5mm mic/speaker port set, useful if the desktops you're switching between need to keep a headset or speakers active.
Who it's for
Same four-VGA-computer setups as the TK-407K, but where you also want to share a microphone and speakers.
Limitations
VGA only; no USB 3.0 hub.
