If you want a complete, plug-and-play wired gaming headset with a microphone, RGB backlight and memory foam ear cushions, choose ZIYOU LANG CY907; if you need replacement memory foam over-ear pads to upgrade a pair of Koss Porta Pro, KSC75 or KPH30i headphones you already own, choose Voarmaks Great Size Over.
• ZIYOU LANG CY907 — biggest strength: it is a finished headset. 40 mm dynamic drivers, a 120° adjustable noise-isolating microphone, RGB backlight and memory foam over-ear cushions, all wired through a single 3.5 mm cable with an inline volume box.
• ZIYOU LANG CY907 — biggest trade-off: it is wired only. There is no wireless mode, and the RGB lighting depends on plugging in the USB cable, so it is tethered to your device.
• Voarmaks Great Size Over — biggest strength: it is a set of memory foam replacement pads built around the Koss driver shape, with a pre-cut hole so the driver sits almost flush and no foam sits between driver and ear.
• Voarmaks Great Size Over — biggest trade-off: it is not a headphone. No drivers, no cable, no microphone — without a compatible Koss model to fit it to, it does nothing.
• Who each pick is for: the CY907 is for someone who wants one box that works out of the gate on PC, PS4, Mac or Windows; the Voarmaks pads are for an existing Koss owner chasing a different sound and a bigger, softer fit.
The CY907 is a self-contained gaming headset, and the spec sheet reads like one. The 40 mm dynamic drivers cover a 20 Hz–20 kHz range with 110±3 dB sensitivity, and ZIYOU LANG describes the tuning as high-resolution stereo with extra bass and crisp treble without distortion. For someone who plays shooters, watches videos and listens to music on the same machine, that is a sensible, general-purpose voicing rather than a specialist one.
The comfort story is the part I find most interesting for a headset in this class. The ear pads are memory protein cotton — a memory foam cushion — in a full over-ear shape, and the head beam is self-adjusting with a soft top cushion. That combination is aimed squarely at long sessions: memory foam compresses around the ear instead of pressing on it, and an auto-adjusting beam means you are not fiddling with a slider every time you put it on. The microphone is a real one too: 6.0 x 5.0 mm, -38±3 dB sensitivity, noise-isolating, adjustable through roughly 120° so you can park it near your mouth and fold it up when you are done.
Buy it if you want one wired headset for a desktop or console setup and you like the idea of a 7-color breathing RGB backlight on the ear cups — it is switched on and off simply by plugging or unplugging the USB cable. The 3.5 mm jack plus the included 1-to-2 splitter means it plugs into most devices with a 3.5 mm socket, and it is listed as compatible with 32-bit and 64-bit Win7/Win8/Win8.1/Win10/XP, plus PS4, Mac and general music listening.
Voarmaks Great Size Over: Who It's For
This is a different kind of product entirely, and it is worth being blunt about that. The Voarmaks Great Size Over is a pair of replacement ear pads — memory foam cushions in a black over-ear shape, measuring 4.09 x 4.09 x 1.42 inches and weighing 21.8 g. There are no drivers inside, no cable, no microphone. It exists to change the fit and the sound of headphones you already have.
The design idea comes from the Koss modding world: audiophiles on forums paired G-Cush foams with the KPH30i, and Voarmaks built a line of compatible pads around that discovery (G-Cush, L-Cush and S-Cush shapes). The G-Cush foam has a distinctive profile — the pre-cut hole means the driver sits almost exactly in it, with no foam between the driver and your ear. That single detail is the whole point of the upgrade. Foam in front of a driver absorbs and softens high frequencies; move it out of the way and you get more clarity and air.
Voarmaks also notes that the Porta Pro driver leans bassy by nature, and that these foams balance it out with a clear, bright sound that stops short of being sharp. Because the pads vary in shape, thickness, material and size, the company frames the whole thing as a way to explore sound — swapping cushions like an acoustic engineer rather than accepting the stock tuning.
Buy it if you own a Koss Porta Pro, KSC75 or KPH30i and you want a roomier, softer over-ear fit with a brighter tonal balance than the stock pads give you. The memory foam enclosure material is the same comfort pitch you would expect from a full-size headphone cushion, just in a much bigger footprint than the thin stock foams.
Skip it if you do not own a compatible Koss model. Also note the KSC35 caveat: Voarmaks states that model needs a portable headband before these pads will work. And if you want a complete headset with a mic, this is simply not that product — buying it will not get you any closer to one.
Side-by-Side: Which Should You Choose?
• Best for gaming with voice chat → ZIYOU LANG CY907. The 120° adjustable noise-isolating mic and inline volume control are built in.
• Best for plug-and-play across devices → ZIYOU LANG CY907. 3.5 mm jack, included 1-to-2 splitter, listed Windows and PS4 compatibility.
• Best for long-session ear comfort on a full-size headphone → ZIYOU LANG CY907. Memory protein cotton over-ear pads plus a self-adjusting head beam with a soft top cushion.
• Best for tuning and experimenting → Voarmaks Great Size Over. Multiple foam shapes and thicknesses let you change the sound signature by swapping pads.
• Best for a bassy driver that needs balancing → Voarmaks Great Size Over. Voarmaks specifically designed these to offset the Porta Pro's bass-forward character.
• Best for a single complete purchase → ZIYOU LANG CY907. Nothing else is required in the box.
• Best for someone who already loves their Koss pair → Voarmaks Great Size Over. You keep the headphone you know and change how it fits and sounds.
In my opinion, most people searching these two names together want a headphone, not a pad — so I would buy the ZIYOU LANG CY907. It gives you drivers, a microphone, memory foam over-ear cushions, RGB backlight and a wired connection that works across PC, PS4 and Mac without buying anything else. The Voarmaks Great Size Over is genuinely clever, and if you already own a Porta Pro, KSC75 or KPH30i it is the more interesting purchase, because it reshapes a headphone you like instead of replacing it. But it only makes sense as an accessory to a Koss you already have. Check the current price on Amazon for both before deciding.
can you sleep with over ear headphones
You can, but neither product is designed for it. The CY907 is a wired headset with a cable and inline volume box, which gets in the way when you lie down, and its RGB lighting runs off a USB connection. The Voarmaks pads are cushions only, so they do not help you sleep at all. If sleeping is the goal, a low-profile design matters more than either of these.
how to wear over ear headphones
The ear cups should sit around your ears, not on top of them — that is what "over ear" means. On the CY907, the self-adjusting head beam and soft top cushion do most of the work: set the beam on your head, then let the memory protein cotton pads settle around each ear. Use the inline volume box on the cable to adjust level.
how to wear over ear headphones properly
Proper fit means the pads fully surround your ears with no pinching at the top of the head or pressure behind the jaw. The CY907's adjustable head beam and memory foam cushions are built to fit different head sizes, so nudge the beam until the weight feels balanced rather than resting on one spot. For the Voarmaks pads, correct seating means the pre-cut hole lines up with the driver.
how should over ear headphones fit
Snug but not tight. The cups should seal gently around the ear for the passive sound isolation the CY907 relies on, while the head beam carries the weight on the top of your head. If you feel pressure after an hour, the fit is wrong — the memory foam should compress, not clamp. On the Voarmaks route, how the pads fit depends on the Koss model and headband you pair them with.
