COOSII AC01 Wired Over-Ear Headphones with Mic

COOSII AC01 are wired over-ear headphones with a built-in microphone and inline volume controls designed for clear stereo sound, comfortable all-day wear, and wide 3.5mm compatibility.

The COOSII AC01 combines a 40mm dynamic driver, large cushioned ear pads, and a foldable, lightweight frame to deliver an immersive listening experience for study, work, travel, and gaming. These headphones plug into any device with a 3.5mm jack and include an HD microphone tuned to reduce wind noise and improve call clarity. The headset is tailored for teens and adults seeking dependable wired sound without the need for batteries or Bluetooth pairing.

How do these headphones improve focus in noisy environments?

The AC01 uses an over-ear, noise-isolating build and enlarged ear cushions to physically block many ambient sounds, helping you concentrate on audio playback. The 40mm diaphragm provides balanced bass and clear mids so audio stays distinct even at moderate volumes.

• Over-ear padding dimensions: 3.54" x 1" surround the ear for passive isolation.
• 40mm DLC dynamic driver for controlled bass and clear midrange.
• Protein leather plus breathable mesh for a seal that reduces external noise.

Will they stay comfortable during long listening sessions?

Comfort is a priority: the AC01 features larger-than-average ear pads and a flexible headband with a center relief zone to spread pressure evenly. Lightweight construction and supple cushioning let you wear the headset for extended periods without discomfort.

• Deeply cushioned ear pads are about one-third larger than typical pads.
• Premium TPU-adjustable headband for a better fit and reduced top-of-head pressure.
• Soft protein leather plus breathable inner mesh to minimize heat build-up.

What controls and connections are included?

The AC01 uses a standard 3.5mm gold-plated plug for universal wired compatibility and an inline module with volume controls and a microphone for hands-free calls and quick audio adjustments. Note that some laptop/PC setups may require an adapter for microphone functionality.

• 3.5mm gold-plated connector compatible with phones, tablets, Chromebooks, and more.
• Inline volume buttons and call controls for simple playback and call handling.
• Integrated HD microphone optimized to reduce wind noise during calls.

How portable and durable are these headphones for travel?

The AC01 folds flat for compact storage and is built with lightweight materials for easy carrying in a backpack or bag. Durable hinges and a foldable design make them practical for commuters, students, and travelers who need reliable wired audio on the move.

• Foldable ear cups and an adjustable headband for compact packing.
• Lightweight frame for reduced fatigue when carried daily.
• Sturdy construction to tolerate regular handling and travel use.

Who is this for: The COOSII AC01 is a good match for teens and adults (recommended ages 12+) who want dependable wired headphones for studying, virtual classes, mobile gaming, or commuting. It suits users who prefer plug-and-play simplicity and physical controls over wireless alternatives, and those who need extra ear padding and passive noise isolation for longer sessions. Check your device’s 3.5mm port compatibility for full microphone and volume-control support; for PC microphone use an adapter may be required.
