AILIHEN C90 Over-Ear Wired Headphones Grey 40mm 3.5mm

Wired over-ear headphones for everyday listening

The AILIHEN C90 is a pair of wired over-ear headphones with a 40 mm dynamic driver and a 3.5 mm connector. They deliver stereo sound with passive noise isolation and include an in-line microphone and volume control. The lightweight frame weighs 300.05 grams and folds into the supplied carry bag for simple transport. They suit students, commuters and office workers who want a straightforward corded headset.

Check the 3.5 mm jack

Your device must provide a standard 3.5 mm audio socket or a compatible adapter for the headphones to work. The in-line volume control and microphone may not function when plugged into a computer, so verify whether you need a separate splitter or USB sound card for full mic and volume operation. The cable is a fixed nylon braided lead that cannot be detached.

Passive isolation with modest power needs

The 17 ohm input impedance and 117 ohm microphone impedance mean the headphones draw very little power from a phone, tablet or laptop. No battery or external amplifier is required, so there is no active noise-cancellation circuitry to generate hiss or heat. The protein-leatherette ear cushions and adjustable headband keep pressure low during long sessions, while the closed-back design naturally reduces sound leakage.
