UGREEN CM383 USB-A to 3.5mm Audio Jack External Stereo Sound Adapter is now in stock at Mascom International for KSh 1,600, bringing a working headset connection back to any laptop or desktop whose built-in jack has stopped responding. This UGREEN CM383 arrives brand new and sealed in factory packaging, carrying UGREEN's SKU 80864 marking, an aluminium alloy body, and a single 3.5mm TRRS socket that handles headphone output and microphone input together. You can collect the UGREEN CM383 from Mascom International at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD.
Kenya's IT support technicians, call centre supervisors in Westlands, university students sitting online tutorials, and freelance transcribers all hit the same wall: a laptop audio jack that crackles, cuts out, or stops registering a headset entirely. Replacing a board-mounted jack costs several times what this adapter does. The UGREEN CM383 steps around the damaged circuit completely by moving audio conversion into its own chip inside the metal body, so the headset you already own keeps working. Nairobi CBD repair shops routinely point customers toward the UGREEN CM383 after quoting five figures for a board-level repair.
Unlike other electronics retailers in Kenya who stock unbranded dongles with no model number and no warranty, Mascom International sells the UGREEN CM383 with its SKU printed on the retail packaging and a 6-month warranty behind it. Users consistently report that cheap generic converters fail within weeks, lose the microphone channel, or introduce hiss during calls. At Mascom International, we're witnessing steady weekly demand from corporate IT departments ordering the UGREEN CM383 in batches of ten and twenty. Walk into our Kimathi Street shop to test one on your own machine, or order for countrywide pay-on-arrival delivery.
Common Questions About the UGREEN CM383 USB-A to 3.5mm Audio Jack External Stereo Sound Adapter
What does the UGREEN CM383 actually do for a laptop with a dead headphone jack?
It replaces the laptop's internal audio path entirely. The UGREEN CM383 carries its own audio chip inside the aluminium body, so once you plug it into a USB-A port, Windows or macOS sees a brand new audio device and routes sound through it instead of the broken onboard jack. Your headset plugs into the adapter rather than into the laptop. Nothing gets opened, unscrewed, or soldered. Nairobi technicians reach for this as a same-day fix when a board-level repair would take a week.
Will the UGREEN CM383 work with a headset that has two separate plugs?
No. This adapter takes a single TRRS plug only. TRRS describes a connector that carries left audio, right audio, microphone, and ground on one 3.5mm pin, which is what modern phone-style headsets use. Older gaming headsets with two plugs, one green and one pink, need a splitter rather than the UGREEN CM383. Mascom International stocks 3.5mm splitters separately if your headset uses the twin-plug arrangement. Count the black bands on your plug before ordering: four contacts means TRRS.
Does the UGREEN CM383 need drivers or software installed?
No installation is needed at all. The UGREEN CM383 runs on the USB Audio Class standard already built into Windows, macOS, Linux, and ChromeOS, so the machine recognises it within two or three seconds of being plugged in. It draws power from the USB port itself and needs no wall charger or battery. For Kenyan buyers watching Safaricom or Airtel data bundles, that matters: there is no driver package to download and no account sign-up before it starts working.
Which computers, consoles, and operating systems work with the UGREEN CM383?
Coverage runs from Windows XP through Windows 11, plus macOS, Linux, ChromeOS, and Raspberry Pi. The UGREEN CM383 also works with PlayStation 5 and PlayStation 4 for headset chat, alongside Microsoft Surface tablets and effectively any USB-equipped desktop. It does not work with PlayStation 3, because that console's USB ports carry no audio signal. Televisions and car head units also fall outside its scope. Any machine that accepts a standard USB audio device will accept this adapter without configuration files.
Can I use the UGREEN CM383 for PlayStation 5 party chat?
Yes, and it is a common reason Kenyan gamers buy it. Plug the UGREEN CM383 into a USB-A port on the console, connect your TRRS gaming headset, then pick it as the chat device in the audio settings menu. One caveat worth knowing upfront: on PlayStation consoles the left and right channels can arrive reversed, because the adapter's sampling capability sits above what the console accepts. Voice chat itself is unaffected. Mascom International will demonstrate this in-store if you bring your headset along.
How does the UGREEN CM383 compare with buying a whole new USB headset?
The adapter costs a fraction of a replacement headset and keeps the one you already own. A decent USB gaming or call-centre headset in Nairobi runs between KSh 4,500 and KSh 12,000, while the UGREEN CM383 sits at KSh 1,600. If your current headset is comfortable and sounds fine, discarding it over a laptop jack fault makes little sense. Buying the adapter also leaves your headset usable on phones, tablets, and any other 3.5mm device you own.
Is KSh 1,600 reasonable pricing for the UGREEN CM383 in Kenya?
It sits in line with the Kenyan market, where this model typically retails between KSh 1,500 and KSh 2,200 depending on the shop. Unbranded equivalents around River Road go for KSh 400 to KSh 700, but arrive with no model number, no warranty, and frequently no working microphone channel. The KSh 1,600 price at Mascom International includes a 6-month warranty and the chance to test the unit on your own machine before you pay anything.
What should I check before ordering the UGREEN CM383?
Confirm three things: your computer has a free USB-A port, your headset ends in a single four-contact plug, and your target device is not a television, car stereo, or PlayStation 3. Desktop users should note the adapter sits close to the socket, so a front-panel USB port is easier to reach than a rear one. Laptop owners short on ports may want a USB hub alongside it. Our team on WhatsApp will confirm compatibility if you send a photo of your headset plug.
Technical Specifications
Core Audio Conversion and Signal Handling
- Dedicated audio chip converts the USB digital stream into analogue output, bypassing the computer's damaged internal circuit
- Sampling reaches 96kHz at 24-bit and 192kHz at 16-bit according to UGREEN's CM383-80864 spec table
- Frequency response spans 20Hz to 20kHz, covering the full range of human hearing for both music and speech
- Signal-to-noise ratio above 100dB keeps background hiss out of recorded voice notes and client calls
- Stereo output feeds left and right earcups independently rather than collapsing everything into one mono channel
- Shielded internal wiring cuts electrical interference from nearby USB drives, phone chargers, and charging cables
- Microphone input shares the same 3.5mm socket, so one plug covers both listening and talking
Connector Standards and Headset Compatibility
- USB-A male plug fits standard USB 2.0 sockets on laptops, desktops, docking stations, and console front panels
- Single 3.5mm TRRS female socket accepts phone-style headsets carrying four contacts on one connector
- Twin-plug headsets with separate green and pink connectors will not work here without an added splitter
- Handles wired earphones, TRRS gaming headsets, TRRS desk microphones, and powered 3.5mm desktop speakers
- Backwards compatible with USB 3.0 and USB 3.2 ports, running at USB 2.0 audio speeds in every case
- Passive wired design means no pairing step, no Bluetooth codec negotiation, and no wireless dropouts mid-call
- Internal detection handles both American and regional headset pinouts, so most TRRS wiring layouts register correctly
Operating System and Device Coverage
- Windows XP, Vista, 7, 8, 8.1, 10, and 11 all recognise the adapter as a standard audio device
- macOS covers Intel and Apple Silicon MacBooks, iMacs, and Mac mini units that carry a USB-A port
- Linux distributions including Ubuntu and Debian load it through the kernel's built-in USB audio driver
- ChromeOS Chromebooks and Raspberry Pi single-board computers both work without editing configuration files
- PlayStation 5 and PlayStation 4 accept it for headset chat; PlayStation 3 passes no audio over USB
- Microsoft Surface tablets, HP EliteBook, Dell Latitude, and Lenovo ThinkPad machines all work directly
- Televisions and car head units fall outside compatibility, since neither routes audio through their USB sockets
Build Quality and Daily Durability
- Aluminium alloy housing resists scratches and denting far better than the plastic shells on generic converters
- Metal body draws heat away from the internal chip during long call-centre shifts and gaming sessions
- Compact dongle shape slips into a laptop bag pocket, a shirt pocket, or a phone case sleeve
- Short lead keeps the adapter tucked against the machine instead of hanging and stressing the socket
- Oxidation-resistant finish holds up in Mombasa and Kisumu humidity where cheaper plated contacts corrode quickly
- No moving parts, no battery, and no charging port, so there is nothing to wear out mechanically
- Housing carries UGREEN branding and the 80864 SKU marking, letting you check the unit against counterfeits
Setup, Power, and Everyday Use
- Plug-and-play operation: insert into USB, wait two seconds, then pick it in sound settings
- Bus-powered from the USB port at 5V, so no wall charger, battery pack, or external supply is required
- Windows lists it under Sound settings as a separate output and input device you select manually
- macOS shows it in System Settings under Sound, where output and input are chosen independently
- Volume adjustment stays with the computer or console rather than a wheel on the adapter body
- Moving it between machines takes seconds, so one unit can serve a desktop by day and a laptop at night
- Draws only milliamps, so it keeps working on a battery-powered laptop during a Kenya Power outage
