Wired 40mm headset for learning
The Kensington K33137 is a wired on-ear headset built for classroom and study use. It connects through a standard 3.5mm plug and has 40mm drivers that deliver deep bass with a wider dynamic range. Padded headband and plush sealed earpads fit a wide variety of ages for long sessions. Flexible earcups allow single-sided monitoring when needed.
Sustained comfort and sound control
The adjustable padded headband and sealed earpads remain comfortable during hours of continuous wear. Output is capped at a maximum of 94db to support safe listening over extended periods. Touch volume and media controls on the earcup let the user adjust level without reaching for the source device. The 60 ohm impedance works with typical classroom computers and tablets.
3.5mm connection with 9-foot reach
The 3.5mm gold-plated jack provides universal analogue compatibility with laptops, tablets and phones. A robust 9-foot cord gives freedom of movement around a desk or lab station without stretching the cable. The plug and cord are designed to withstand heavy daily use in shared environments. No battery or wireless pairing is required.

Questions about this item
How warm or noisy does the K33137 get during all-day classroom use?
The passive on-ear design has no active electronics, so it generates no heat and produces no fan or coil noise during extended sessions.
What device must I already own for the 3.5 mm plug to work?
Any source with a standard 3.5 mm audio jack — laptop, tablet, phone or desktop — will drive the 60 ohm drivers without extra hardware.
Will the 9-foot cord and gold-plated jack still fit older audio ports on legacy PCs?
Yes, the 3.5 mm connector is the long-standing analogue standard, so it mates reliably with decades-old sound cards and front-panel headers.
