If you want a complete, ready-to-go wireless headset for library study sessions — one with a detachable mic, three connection modes and a 50-hour battery — choose ZIYOU LANG L80; if you need to rescue a pair of Bose NC700 headphones whose ear cushions have cracked, peeled or gone flat, choose Hmoke Replacement Ear Pads. These two products only look like competitors because both sit in the memory foam over ear headphones space. They solve completely different problems, and the right answer depends entirely on what you already own.
• ZIYOU LANG L80 — biggest strength: a full audio package in one box: 40mm dynamic drivers, Bluetooth 5.3, a 2.4GHz dual-head USB-C/USB-A dongle, 3.5mm wired mode, a detachable noise-canceling mic and a claimed 50 hours of battery life.
• ZIYOU LANG L80 — biggest trade-off: it is a self-contained headset, so it does nothing for headphones you already own, and its noise control is sound isolation rather than active noise cancellation.
• Hmoke Replacement Ear Pads — biggest strength: a focused, tool-free refresh for Bose NC700 owners, using slow-rebound memory foam and protein leather at roughly a 3–5 minute install.
• Hmoke Replacement Ear Pads — biggest trade-off: they fit only the Bose NC700. If that is not your headphone, they are the wrong purchase entirely.
• Who each pick is for: ZIYOU LANG L80 for someone who needs a whole wireless headset for the library, gaming and calls; Hmoke Replacement Ear Pads for someone who already loves their Bose NC700 but hates the worn-out cushions.
The L80 is a tri-mode headset, and that word "tri" is the whole story. You can run it over Bluetooth 5.3, over a 2.4GHz wireless connection using the bundled dongle, or over a plain 3.5mm cable. The dongle itself has a dual head, so it plugs into either a USB-C port or a standard USB-A port without an adapter — useful when you move between a laptop, a console and a phone in the same afternoon. Switching between modes is done by double-clicking the power button.
For library use specifically, the pieces that matter are the ones that keep you quiet and comfortable. First, the mic is detachable. If you are studying, you pull it off and nobody around you has to look at it. Second, the earcups use soft, breathable memory foam wrapped in a mix of cloth and leather, which is a sensible choice for long sessions — leather alone tends to get warm, and the cloth side of that combination helps. Third, the whole thing weighs 184 grams, which is genuinely light for an over-ear headset, and the headband is adjustable. If you have ever taken a heavy headband headphones pair off after two hours with a sore spot on your crown, that number will mean something to you.
On the audio side, ZIYOU LANG lists 40mm dynamic drivers with a 20Hz–20,000Hz frequency range and a 3D surround effect, plus a quoted latency of 20 milliseconds in wireless use. That latency figure is the interesting one for anyone pairing a headset with a screen: 20ms is low enough that lip-sync and game audio stay believable, which is why the L80 is positioned as a gaming headset first. The 600mAh battery is rated for up to 50 hours of average life, so a week of library trips between charges is realistic on paper.
Who should skip it: anyone who already owns a premium pair of headphones and just wants to fix the cushions. The L80 cannot help you there. Also skip it if you specifically want active noise cancellation — the L80 uses sound isolation, which is a passive seal, not electronic cancellation.
Hmoke Replacement Ear Pads: Who It's For
Hmoke makes one thing, and makes it narrowly: replacement ear pads for the Bose NC700. That narrowness is a feature. Because the pads are built to match the shape, size and attachment points of the NC700's earcups, they are designed to sit flush, avoid gaps and lifted edges, and stay put during daily use. A generic pad that almost fits is worse than a worn original, so model-specific geometry is the entire point here.
The comfort story is straightforward and, again, memory foam over ear headphones logic. Slow-rebound memory foam spreads pressure more evenly around the ear, thick supportive padding softens long listening sessions, and a breathable inner mesh is there to move air and cut down heat and moisture. The outer surface is smooth protein leather, which is easy to wipe clean. Hmoke describes the padding as extra-thick and durable, and the whole point is that a tired pair of NC700s feels and looks refreshed rather than replaced.
Installation is the part most people worry about, and Hmoke addresses it directly: no tools, no glue, remove the old pads and press the new ones into place. The listing says most people finish in about 3–5 minutes and pitches it as a 3-minute job. There is also a 1-year manufacturer warranty and a stated 24-hour reply window through Amazon Messages if something does not line up.
Who should buy them: Bose NC700 owners whose cushions are cracked, peeling, flattened or misshapen, and who would rather spend a few minutes at the kitchen table than buy a whole new headset. Students are a natural fit — a library headphone that has lost its seal leaks sound both ways.
Side-by-Side: Which Should You Choose?
• Best for a complete wireless setup → ZIYOU LANG L80. Bluetooth 5.3, a 2.4GHz dongle and 3.5mm wired in one device.
• Best for reviving headphones you already love → Hmoke Replacement Ear Pads. Designed specifically for the Bose NC700.
• Best for battery life → ZIYOU LANG L80. A 600mAh battery rated at up to 50 hours of average life.
• Best for a quick, low-effort fix → Hmoke Replacement Ear Pads. No tools, no glue, roughly 3–5 minutes.
• Best for voice chat and calls → ZIYOU LANG L80. A detachable omnidirectional noise-canceling mic with a 360° adjustable angle and a mute button, though mute behaviour varies by connection mode.
• Best for long study sessions → both, for different reasons. The L80 gives you breathable cloth-and-leather memory foam at 184 grams; the Hmoke pads give you slow-rebound foam and a breathable mesh to replace flattened cushions.
• Best for gaming on PC or console → ZIYOU LANG L80. 40mm drivers, a 3D surround effect and a quoted 20ms latency.
• Best if you want active noise cancellation → neither. The L80 uses sound isolation, and the Hmoke pads are a passive seal. Neither is an ANC product.
If I had to pick one, I would buy the ZIYOU LANG L80 — but only because it is the more complete product for the library scenario this article is built around. It gives you a headset, a mic, three ways to connect and a long battery rating in a single purchase, and the 184-gram weight and cloth-and-leather memory foam earcups are the details that actually matter when you are sitting still for hours. That said, my recommendation flips completely if you already own Bose NC700s: in that case the Hmoke Replacement Ear Pads are the smarter buy, because a 3–5 minute swap is a far better outcome than retiring a headphone you like. Check the current price on Amazon for whichever one matches your situation.
FAQ
can you sleep with over ear headphones
how to wear over ear headphones
Slide the headband over the top of your head and let each earcup sit around your ear rather than on it — the cushion should surround the ear, not flatten it. The L80 has an adjustable headband, so set the sliders so the band rests lightly on your crown. If you are using the L80's mic, angle it toward your mouth and mute it when you are not talking.
how to wear over ear headphones properly
Properly means the earcups fully enclose your ears with an even seal and no pressure hotspots. On the L80, the memory foam earcups use a cloth-and-leather mix, and the light 184-gram build helps here. On a Bose NC700 with fresh Hmoke pads, the model-specific shape is designed to sit flush around the earcups and avoid gaps or lifted edges, which keeps the seal consistent.
how should over ear headphones fit
Snug but not tight. The band should rest on your head without pinching, and the cushions should seal around your ears without you having to press them down. If the seal feels weak or sound leaks, worn cushions are a common cause — which is exactly the problem Hmoke's slow-rebound memory foam pads are made to solve on the Bose NC700. On the L80, adjust the headband first before judging the fit.
