If you want a classroom set with mixed colors, a 3.5 mm connection, and a four-foot cord for gaming on compatible devices, choose TJZXGUI Bulk Classroom Headphones; if you need USB-C classroom headphones for gaming on a USB-C device, choose OSSZIT USB C Headphones. For gaming, the connection on the device you plan to use is the deciding factor: these are both wired, on-ear classroom sets, but their plugs are not interchangeable.
The TJZXGUI set emphasizes broad 3.5 mm compatibility and easy storage, while the OSSZIT set is built around a direct USB-C connection and a simpler black appearance. Neither has noise control, so I would choose based on the port and classroom setup rather than expecting either pair to isolate you from surrounding sound.
• TJZXGUI’s biggest strength: A 3.5 mm jack and four-foot cable connect to many devices with that port; its trade-off is that it will not connect directly to USB-C-only devices without a suitable adapter.
• OSSZIT’s biggest strength: USB-C plug-and-play use needs no charging, pairing, or adapter on compatible devices; its trade-off is that it does not work with 3.5 mm or Lightning devices.
• TJZXGUI design: Twenty mixed-color headphones, an adjustable flexible headband, and ear cups that rotate 90 degrees for stacking and storage.
• OSSZIT design: Twenty individually packed black headphones with an adjustable headband and soft ear cushions; the sheet does not specify a cable length or folding ear cups.
• For whom: Choose TJZXGUI for classrooms with a mix of devices using 3.5 mm jacks; choose OSSZIT when the intended devices have USB-C audio connections.
TJZXGUI is the more adaptable option when a classroom, library, or household uses several kinds of equipment. Its standard 3.5 mm plug is listed as compatible with devices such as laptops, PCs, desktops, tablets, phones, and MP3 players that have that connection. The four-foot cable gives a wired connection without requiring charging or pairing. For gaming, that makes it a straightforward choice when the console, computer, or other device has a 3.5 mm headphone jack.
The pack contains twenty headphones in mixed colors, which can make it easier to distinguish one student’s pair from another in a shared room. The adjustable, flexible headband is designed to fit children, and the ear cups rotate 90 degrees to make stacking and storage easier. Those details are useful in a classroom where headphones may be put away between lessons. The listed audio range is 20 Hz to 20,000 Hz, and the impedance is 32 ohms; those are specifications, not a promise of a particular gaming sound experience.

OSSZIT is aimed at a classroom or computer lab where USB-C is the connection students need. The set includes twenty individually packed headphones, and the product information describes plug-and-play audio with no charging, pairing, or adapter required on compatible devices. The listed compatible device types include Chromebook, tablet, smartphone, laptop, and PC, provided they support the needed USB-C audio connection. For gaming, this is the direct option when the device has USB-C audio and no suitable 3.5 mm jack.
The headphones are black, wired, and on-ear, with an adjustable headband and soft ear cushions intended to reduce pressure during longer use. The description specifically points to speech-heavy tasks such as testing instructions, educational videos, and language learning. The impedance is listed as 32 ohms. OSSZIT also states that these headphones are not compatible with 3.5 mm or Lightning devices, so checking the actual port and audio support matters before choosing a class set.
Who should skip it: Skip OSSZIT if your classroom equipment relies on 3.5 mm or Lightning connections. A USB-C plug is convenient only when the device supports USB-C audio; the product does not include a stated alternative connection.
• Best for a 3.5 mm headphone jack → TJZXGUI Bulk Classroom Headphones. Its standard jack is the right match for compatible laptops, desktops, tablets, phones, and other listed device types.
• Best for direct USB-C audio → OSSZIT USB C Headphones. They are designed to play audio when connected to a compatible USB-C device, without charging or pairing.
• Best for a mixed-device classroom → TJZXGUI. The 3.5 mm connection suits a broad range of equipment that has that port, though it will not directly fit USB-C-only hardware.
• Best for USB-C computer labs → OSSZIT. Its connection avoids the need for an adapter on compatible USB-C equipment, but it cannot serve devices that require a 3.5 mm or Lightning plug.
• Best for color-coding or quick visual identification → TJZXGUI. The set comes in mixed colors, a practical distinction when many pairs are stored together.
• Best for individually packed headphones → OSSZIT. Each unit is individually packed, which may suit a classroom distributing headphones to students.
• Best for compact stacking and storage → TJZXGUI. The ear cups rotate 90 degrees; that specific storage feature is not listed for OSSZIT.
• Best for gaming on a compatible device → Match the plug to the device. Choose TJZXGUI for a 3.5 mm jack and OSSZIT for USB-C audio. Neither product lists noise control, so neither is the obvious pick if blocking out nearby classroom activity is your priority.
Buying Considerations
Start by checking the exact device each student will use, not just the device category. A Chromebook, tablet, phone, or PC may have different connection options depending on the model. OSSZIT is explicitly not compatible with 3.5 mm or Lightning devices. TJZXGUI uses a 3.5 mm jack, so it is not a direct USB-C connection. If adapters are part of your setup, confirm they support the intended audio connection rather than assuming the headphone plug alone guarantees compatibility.
For gaming, both models are wired, which means the device connection is central to the choice. The available specifications do not establish that either is designed specifically for gaming, and neither lists noise control. TJZXGUI gives a stated frequency range of 20 Hz to 20,000 Hz, while OSSZIT emphasizes clear speech for educational audio. Those details can help set expectations, but they do not establish a head-to-head sound-quality advantage.
If the decision is for a class set, also consider whether students need one visible color scheme or a way to tell pairs apart. TJZXGUI offers mixed colors; OSSZIT is black. Both have adjustable headbands, and both are described for children, teens, and adults. OSSZIT’s description says it is not for children under three. These practical distinctions may matter more than small differences in the published audio details when the headphones will be shared across a group.
In my opinion, I would choose TJZXGUI for a classroom or gaming setup that uses 3.5 mm devices because its connection is broadly useful and its rotating cups make storage easier. I would choose OSSZIT instead for USB-C-only equipment where direct plug-and-play audio is the priority. For gaming, my recommendation is TJZXGUI when the device has a 3.5 mm jack; I would not buy either set before confirming the device’s audio port.
Neither is presented as a dedicated gaming headset, so start with the device connection. TJZXGUI uses a 3.5 mm jack; OSSZIT uses USB-C and requires a compatible USB-C audio connection.
Can I use OSSZIT USB C Headphones with a 3.5 mm device?
