• Generic TZX 7.1 — biggest strength: a USB 7.1 surround sound card with separately adjustable levels, plus a small in-line remote for both sound and mic, so everything is controlled from the cable rather than on-screen software.
• Generic TZX 7.1 — biggest trade-off: it is USB only, with no 3.5 mm jack, so it will not plug into a phone, tablet or a console controller that only accepts a standard headphone plug.
• CASLSI Gaming Headsets — biggest strength: broad multi-platform compatibility through a 3.5 mm jack, covering PS5, PS4, Xbox Series X/S, Switch, PC, tablets and phones, with an omni-directional noise-cancelling mic on a 360-degree adjustable boom.
• CASLSI Gaming Headsets — biggest trade-off: it is a wired analog headset, so there is no USB sound card and no in-line remote — the surround processing and volume control depend on whatever device you plug it into.
• Who each pick is for: the TZX 7.1 suits a desktop or laptop player who wants a tidy USB setup; the CASLSI suits someone who plays across several devices and wants one headset to move between them.
The TZX 7.1 is built around one idea: put the audio processing in the cable. Its USB connection feeds a 7.1 sound card that delivers surround sound with separately adjustable levels, which means you can nudge individual channels rather than accept one flat mix. The small in-line remote handles both volume and mic, so muting yourself or riding the level mid-match does not mean alt-tabbing out of the game. For a PC or laptop player, that is a genuinely convenient design.
Comfort is clearly a priority here too. The headband uses four pieces of padding, and the ear pads are PU leather over an over-ear shape. The headband is reinforced and offers nine levels of height adjustment, which is more granular than the usual click-or-two sizing — useful if you sit between sizes or share the headset with someone else. The mic is retractable, so it tucks away when you are not talking, and the cable itself retracts as well. Both are small touches that matter on a desk.
Who should skip it? Anyone gaming mainly on a console that expects a 3.5 mm plug, or anyone who wants to use the same headset with a phone or tablet. There is no headphone jack at all here — it is USB, full stop. It also has no active noise control, and it is not water resistant, so it is a desk-bound headset rather than a travel one. If your setup is a gaming PC or laptop and nothing else, the TZX 7.1 lines up neatly.
The CASLSI K80 is the flexible one. Its defining feature is the 3.5 mm audio jack, which is why it can claim compatibility with PS5, PS4, Xbox Series X/S, Switch, PC, tablets and phones in one product. If you have ever wished you could unplug a headset from your console and immediately use it on a laptop call, this is the design that allows it. The 5.9-foot braided cable is described as high-tension and tangle-resistant, which is a practical detail for a headset that gets moved around.
The mic is the other standout. It is a high-sensitivity, omni-directional unit with noise-cancellation technology aimed at cutting background noise, and it rotates through 360 degrees so you can position it at whatever angle suits your voice. Combined with 7.1 surround sound for positional accuracy, that is a sensible pairing for squad play where callouts matter as much as hearing footsteps. The ear cushions use a protein hybrid design with high memory foam and soft fabric, which points to a lighter, less sweat-prone feel than plain leatherette over long sessions.
The trade-offs are the flip side of that flexibility. Because it is analog over 3.5 mm, there is no onboard sound card and no in-line remote — your surround processing, volume and mute behaviour come from the device you plug into. Some consoles and phones handle that differently, so the experience is less consistent than a dedicated USB card. It is also black only, and the data sheet lists no folding or swivel feature. If you want one headset for everything, though, it is the more adaptable of the two.
• Best for PC and laptop only → Generic TZX 7.1. The USB connection and 7.1 sound card are a clean fit for a desktop or notebook.
• Best for multi-platform use → CASLSI Gaming Headsets. PS5, PS4, Xbox Series X/S, Switch, PC, tablets and phones from a single 3.5 mm jack.
• Best for on-cable control → Generic TZX 7.1. The in-line remote adjusts both sound and mic without touching software.
• Best for voice clarity → CASLSI Gaming Headsets. Omni-directional noise cancellation plus a 360-degree adjustable boom.
• Best for fit adjustment → Generic TZX 7.1. Nine levels of headband height adjustment and a four-piece padded headband.
• Best for long-session comfort → CASLSI Gaming Headsets. Memory foam and soft fabric cushions are designed to reduce pressure and heat.
• Best for a tidy desk → Generic TZX 7.1. The retractable mic and retractable cable keep things out of the way.
• Best if you might switch devices later → CASLSI Gaming Headsets. A 3.5 mm plug works almost anywhere; USB does not.
If I were buying for myself, I would take the CASLSI Gaming Headsets. In my opinion, the 3.5 mm jack is the more future-proof choice: it works on consoles, PC, tablets and phones, so the headset does not become useless the moment I change what I play on. The noise-cancelling adjustable mic and the memory-foam hybrid cushions also fit how most people actually use a headset — long sessions with a lot of talking.
That said, I would pick the Generic TZX 7.1 without hesitation if my gaming lived entirely on a PC or laptop. The USB 7.1 sound card and the in-line remote give you control the CASLSI simply cannot offer over an analog cable. Decide which of those two situations sounds like your setup, then check the current price on Amazon before you commit.
FAQ
Not universally. The CASLSI wins on device compatibility and mic noise cancellation; the TZX 7.1 wins on onboard 7.1 processing and in-line control. Which is "better" depends entirely on whether you game on one PC or across several devices.
It is a USB headset with no 3.5 mm jack, and its listed compatible devices are laptops, desktops and gaming consoles. If your console setup relies on a standard headphone plug, the CASLSI is the safer match.
No. It connects over a 3.5 mm wired jack, so surround sound and volume are handled by the device you plug it into. The TZX 7.1 is the one with the built-in 7.1 USB sound card.
Both use padded, over-ear designs. The TZX 7.1 leans on PU leather cushions and a four-piece padded headband with nine height settings; the CASLSI uses memory foam with soft fabric. In my opinion the CASLSI's fabric cushions will feel cooler over several hours, while the TZX 7.1 offers finer fit adjustment.
