Wired circumaural headphones with 40 mm drivers
The Kensington 33137 is a pair of over-ear headphones built for listeners who want a simple analogue connection. A 3.5 mm gold-plated plug connects directly to laptops, desktops or mobile devices without adapters or batteries. The 9-foot cable gives plenty of reach for desk or studio setups. Padded headband and sealed earpads support extended sessions.
Gold-plated 3.5 mm plug and 9-foot cord
The gold-plated connector resists corrosion and maintains a clean signal path over time. A single 9-foot cable eliminates the clutter of extension leads while allowing freedom of movement. No inline remote, microphone or volume control is included, so the signal stays unaltered from source to driver. Bulk packaging reduces waste for institutional buyers.
32-ohm impedance and 103 dB sensitivity
At 32 ohms the headphones draw modest power from standard headphone outputs, while 103 dB sensitivity delivers loud, clear audio without a dedicated amplifier. The 20 Hz–20 KHz frequency response covers the full audible range through dual 40 mm Mylar cone drivers. Buyers needing wireless freedom, active noise cancellation or a detachable cable should consider other models.

Questions about this item
Will the 9-foot cord or gold-plated 3.5 mm plug need replacing after long-term daily use?
The 9-foot cord and gold-plated 3.5 mm plug are built to withstand heavy daily use, so no scheduled replacement is expected under normal conditions.
What limits how loud the 40 mm drivers can play continuously without distortion?
The 32-ohm impedance and 103 dB sensitivity set the electrical and acoustic ceiling; driving them beyond the source device's clean output level introduces distortion first.
How much heat do the circumaural earpads trap during an all-day session?
Padded circumaural cups seal around the ears, which retains some warmth over many hours, but the passive design adds no active heat of its own.
