PLANTRONICS AC01 Over-Ear Wired Headset 40mm Driver 3.5mm Jack Black Blue

Over-Ear Headset with 40 mm Drivers

The Plantronics AC01 is a wired stereo headset built around 40 mm dynamic drivers and a 3.5 mm analogue jack. It is intended for students, office workers and travellers who want a single headset for calls, music and video on laptops, tablets or phones. The over-ear cups use protein leatherette pads and an adjustable TPU headband sized for users aged 12 and above.

Passive Isolation Limits on a 3.5 mm Connection

The headset relies on physical ear-cup sealing to block up to 85 % of ambient noise without active electronics. Because the 3.5 mm plug carries only an analogue stereo signal, microphone quality and maximum output of 117 decibels depend entirely on the host device’s built-in codec and amplifier. No digital processing, surround modes or software equalisation are available through this interface.

Upgrade from Basic Earbuds or Thin On-Ear Models

Buyers moving up from packed-in earbuds or shallow on-ear headphones gain larger 40 mm drivers, deeper cushions and a foldable frame that stores flat. The jump is worthwhile when longer sessions demand better bass response, clearer mid-range and all-day comfort. It is not suited for users who need wireless freedom, active noise cancellation or a detachable boom microphone for competitive gaming.
