Classroom Headset with TRRS Plug
The HamiltonBuhl FV-BLK is a wired over-ear headset built for daily classroom and testing use. Its 40mm drivers deliver a 50Hz-20KHz frequency response at 32 ohms impedance and 105dB sensitivity. The 3.5mm TRRS connector works with tablets, laptops, smartphones and most gaming systems.
Simple Plug-and-Play Setup
Insert the 3.5mm TRRS plug into a single combo audio jack and the headset is ready; no drivers or software are required. The 5-foot Dura-Cord uses a 120-degree angled plug to reduce strain on the port. The braided nylon jacket resists chewing and tangling, though the fixed cable cannot be replaced if severed.
Wired TRRS Connection Limits
The analogue 3.5mm TRRS interface carries stereo audio and microphone signals on one plug, so it needs a combined headset port or a splitter for separate mic and headphone jacks. Audio quality is bound by the host device’s onboard codec rather than an internal DAC. The passive design draws no power but offers no digital processing or wireless freedom.
