Retro Over-Ear Headphones with 40mm Drivers

These black over-ear headphones deliver Hi-Fi stereo sound through 40mm drivers with a 32-ohm impedance. The 3.5mm connector provides universal wired compatibility with most mobile phones and audio playback devices. A lightweight 6-ounce build and cushioned ear cups support extended listening sessions.

Upgrade from Basic Earbuds or Damaged Cables

The jump is worth it when you want passive noise isolation and a foldable design that survives daily transport. The retro 80s and 90s aesthetic adds a distinctive look while the attached cord removes the need for charging. Buyers who need active noise cancellation or wireless freedom should look elsewhere.

Sustained Comfort and Consistent Output

Passive noise cancelling and 102-decibel sensitivity maintain clear audio during long playback periods without battery drain. The 20-hertz frequency response and 102-decibel signal-to-noise ratio keep distortion low across extended use. The built-in microphone with 3K-ohm impedance handles voice calls reliably over time.

Questions about this item

Will the 40 mm driver cups clear my ears without pressing on them?

The over-ear cups fully surround the ear; at 6 ounces the lightweight frame keeps pressure low for long sessions.

Do I just plug the 3.5 mm jack in, or is there a pairing step?

It is a wired analogue connection — insert the 3.5 mm plug into the device socket and audio plays immediately, no pairing or power needed.

Are the ear pads replaceable when they wear out?

The pads are not user-replaceable; if the cushions degrade the entire headset would need replacement.
