COOSII AC01 Over-Ear Headphones Wired, Passive Noise Review
For just $25, the COOSII AC01 deliver surprising comfort and a built-in mic, but you'll have to compromise on sound quality and deal with a wire.
The 30-Second Version
The COOSII AC01 are budget wired over-ear headphones that cost about $25. They're incredibly comfortable and include a microphone, but sound quality is just average and they lack features like Bluetooth or active noise cancellation. A solid pick if you're on a tight budget and just need something simple that works.
Overview
If you're looking for cheap over-ear headphones that won't break the bank, the COOSII AC01 are worth a look. For about $25, you get a wired, foldable pair with a built-in microphone and volume controls. They're designed for passive noise isolation, which means they block sound by physically covering your ears rather than using fancy electronics. People searching for 'budget wired headphones for laptop' or 'cheap over-ear headphones with mic' will find these on the list, and they're aimed at students, travelers, or anyone who just needs a simple, no-fuss audio solution.
Performance
Let's be real: you're not buying $25 headphones for audiophile-grade sound. In our database, the AC01's sound quality scores in the 38th percentile, which is about what you'd expect. They get loud enough thanks to the 32-ohm impedance, and the 40mm drivers deliver a balanced sound that's fine for podcasts, casual music, and video calls. The microphone actually scores surprisingly well at the 80th percentile, meaning call clarity is decent for the price. Just remember, the volume controls and mic don't work on PCs without a special adapter, which is a bit of a hassle.

Value & Pricing
At $25, the value proposition is simple: you get what you pay for. These are some of the cheapest over-ear headphones you can find that don't feel like total junk. Compared to throwing down $300 for Sony WH-1000XM6s, you're saving a ton of cash, but you're also giving up wireless freedom, ANC, and premium sound. For a student on a tight budget or someone who needs a backup pair for travel, the price is hard to beat.
Price History
vs Competition
The obvious competitors are other budget wired headphones like the DOQAUS Over-Ear Bluetooth model, which adds wireless capability for a bit more money. If you care about sound, stepping up to the Sennheiser Momentum 4 Wireless is a massive jump in audio quality and features, but you're paying ten times the price. The Sony WH-1000XM6 and Apple AirPods Max are in a completely different league with active noise cancellation and wireless convenience, but they cost hundreds more. The COOSII AC01's main advantage is pure, simple affordability and surprisingly good comfort.

Common Questions
Q: Are the COOSII AC01 headphones good for gaming?
They're okay for casual gaming thanks to the decent microphone, but they score only 51.6/100 for gaming in our tests. For competitive gaming, you'd want a dedicated gaming headset with better spatial audio.
Q: Do these headphones work with a PC?
Yes, they'll play audio through the 3.5mm jack, but the inline microphone and volume controls won't work on most PCs without a separate adapter that splits audio and mic signals.
Q: How is the noise cancellation on these?
They don't have active noise cancellation (ANC). They use passive noise isolation, which means the over-ear design blocks some sound physically, but it's not as effective as ANC headphones, especially for low-frequency noise.
Q: Can you use these headphones with a phone?
Yes, they're compatible with any device with a 3.5mm audio jack. For iPhones, you'll need a Lightning to 3.5mm adapter, and the inline controls should work for music and calls.
Who Should Skip This
Skip these if you're an audiophile, a frequent flyer who needs serious noise cancellation, or someone who hates dealing with wires. They're also not the best for professional studio work (scoring 48.1/100) or if you need something ultra-durable for daily rough use. In those cases, look at wireless options like the Sony WH-1000XM6 for travel or a dedicated studio monitor from brands like Audio-Technica.
Verdict
Should you buy these? If you need the absolute cheapest over-ear headphones that are actually comfortable and have a mic, yes. They're perfect for a kid's first headset, a travel backup you won't cry over if they get lost, or a basic pair for video calls on a Chromebook. But if you care about sound quality, want wireless freedom, or need serious noise blocking, you'll outgrow these fast. For $25, they do the job without any frills.
