Single-Ear Wired Headset for Gaming and Calls

The Joso CO25-1 is a unilateral over-ear headset finished in graphite. It connects through a 3.5 mm jack and includes USB-C and USB-A adapters for broad device support. The design targets gamers needing chat audio on consoles or professionals taking calls on laptops and tablets. It is not suited for users who want stereo immersion or dual-ear isolation.

3.5 mm Analogue Limits and Console Setup

The analogue 3.5 mm connection relies on the host device for power and signal quality, so maximum volume and mic gain vary by controller or sound card. A one-time settings adjustment is required on PS5, PS4 and Xbox consoles before the headset functions correctly. Older Xbox One controllers without a 3.5 mm port are not compatible. Buyers who need digital audio processing or surround sound should look elsewhere.

Lightweight Frame with Braided Cable and Rotating

The plastic and faux-leather construction weighs 0.1 kg and measures 21 x 10 x 16 cm for extended comfort. A 5.91 ft braided cable protects oxygen-free copper conductors from tangles and wear. The boom microphone rotates 270° for left or right positioning and bends to maintain clear voice pickup. Touch-sensitive in-line controls handle volume and mute without software.

Questions about this item

Is the CO25-1 sold with both 3.5 mm and USB connections?

The headset uses a 3.5 mm plug and the box includes a USB-C to USB-A adapter for devices that only have USB ports.

What does the 40 mm driver and 32 ohm impedance mean for daily use?

The 40 mm driver handles chat and game audio while the 32 ohm load is easily driven by controllers, phones and laptops without extra amplification.

How does the 3.5 mm jack limit microphone quality on a PC?

The single 3.5 mm TRRS plug carries both stereo output and the -42 dB microphone signal, so mic quality depends on the host device's built-in codec.
