If you want straightforward USB-C wired earbuds for library listening, choose LUDOS FEROX USB C; if you need a lightweight, ear-hook-style fit for gaming and calls, choose Piluyaa Gaming Headphones IEM. LUDOS keeps the setup simple with in-ear sound isolation and a protective case, while Piluyaa adds ear fins, three pairs of tips, and an inline microphone. Neither is wireless, and neither should be mistaken for a waterproof or bone-conduction design.
• LUDOS FEROX USB C: USB-C wired connection, in-ear sound isolation, and a protective case; trade-off: the listed package does not specify multiple ear-tip sets or an ear-hook fit.
• Piluyaa Gaming Headphones IEM: lightweight 2.3-gram-per-earpiece design, ear fins, three pairs of silicone tips, and an inline mic; trade-off: its remote does not support volume adjustment.
• LUDOS is for someone who wants a simple, direct USB-C listening setup for a library or everyday device use.
• Piluyaa is for someone who prioritizes a more secure fit, call controls, and gaming-oriented use.
• Both are wired USB-C in-ear earphones with dynamic drivers; neither offers a wireless connection.
The LUDOS FEROX USB C is a no-frills wired option for a listener who wants to connect directly to a USB-C device. Its in-ear rounded tips and sound-isolation design make it a reasonable match for focused listening in a library, where keeping audio contained can matter. The cable connection also means there is no wireless pairing step to manage.
The product uses a dynamic driver and has a listed impedance of 32 ohms. A protective case is included, and the stated warranty is five years. Those details make the FEROX appealing if you prefer a basic wired set with a case for storage and a clearly stated warranty period.
I would skip it if you specifically want an ear fin or memory-style ear hook to help keep an earbud in place, or if inline microphone and track controls are priorities. Those features are not specified for this model. Its stated controls are for calls, operated with a button-style controller.
Piluyaa’s QKZ ENZO is the more feature-rich fit choice on paper. Each earpiece is listed at 2.3 grams, and its design adds a soft ear fin and a memory ear hook intended to wrap around the ear. Three pairs of silicone tips are included, giving you more fit options than the LUDOS package specifies. That combination may suit someone who wants the cable and earpieces to feel more secure during gaming or other movement.
The USB-C wired connection works with compatible Type-C audio devices. Piluyaa also includes an inline microphone and remote buttons for answering or ending calls, pausing or playing audio, and skipping tracks. Its 11 mm dynamic driver and 16-ohm impedance are listed alongside a sound profile described as bright and clear, with bass and treble emphasized in the product information. These are design and feature claims, not a guarantee that every listener will hear the same result.

We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-19 · 10 min read · Independent comparison
• Best for a simple USB-C library setup → LUDOS FEROX USB C. Its in-ear design and stated sound isolation suit focused listening without adding a separate fit system.
• Best for a more secure over-ear fit → Piluyaa. Its ear fins and memory ear hooks are designed to help hold the earpieces in place.
• Best for included fit options → Piluyaa. The package lists three pairs of silicone tips; the LUDOS details list rounded tips but do not specify multiple sets.
• Best for call and playback controls → Piluyaa. Its inline remote handles calls and basic playback, though it cannot adjust volume.
• Best for a protective storage case → LUDOS FEROX USB C. A protective case is listed among the included items.
• Best for a stated long warranty → LUDOS FEROX USB C. Its product details specify a five-year warranty.
• Best for someone considering the best deep bass clip on earbuds for library listening → neither is a clip-on design. Both are in-ear wired models; Piluyaa describes bass in its sound profile, but the available details do not establish a clip-on fit.
• Best for someone searching for voice assistant sleep headphones for library use → neither is described that way. These are wired in-ear earphones, and the supplied specifications do not identify sleep or voice-assistant features.
In my opinion, I would choose the LUDOS FEROX USB C for a library-focused buyer who wants a straightforward wired connection and stated sound isolation. Its protective case and five-year warranty are useful additions, while its design stays simple.
I would pick Piluyaa instead if a secure ear-hook fit, included tip choices, and inline call and playback controls matter more. For my library recommendation, though, I prefer the LUDOS’s explicitly listed isolation.
The LUDOS FEROX is the clearer match on the listed features because it specifies in-ear sound isolation. Piluyaa’s details emphasize fit, calls, and playback controls, but do not specify noise isolation.
No. Its inline remote is listed for answering or ending calls and controlling playback, including skipping tracks. The product details specifically say volume adjustment is not supported.
Neither product is described as waterproof or bone conduction. Both are wired, in-ear earphones with dynamic drivers, and no waterproof rating is provided in the available product details.
Piluyaa has the more explicit call and gaming-oriented feature set: an inline microphone, call and playback buttons, and an ear-hook-style fit. LUDOS lists call control, but its supplied details do not specify an inline microphone or gaming-focused fit.

LUDOS FEROX USB C vs Piluyaa Gaming Headphones IEM at a Glance
• LUDOS FEROX USB C: USB-C wired connection, in-ear sound isolation, and a protective case; trade-off: its listed package does not specify multiple ear-tip sets or an ear-hook fit.
• Piluyaa Gaming Headphones IEM: lightweight 2.3-gram-per-earpiece design, ear fins, three pairs of silicone tips, and an inline mic; trade-off: its remote does not support volume adjustment.
• Choose LUDOS for a simple wired setup for a library or everyday listening.
• Both are wired USB-C in-ear earphones with dynamic drivers.
The LUDOS FEROX USB C is a straightforward option for someone who wants to connect directly to a USB-C device. Its rounded in-ear tips and stated sound-isolation feature make it a reasonable match for focused listening in a library. The wired connection also avoids the need for wireless pairing.
It uses a dynamic driver and has a listed impedance of 32 ohms. A protective case is included, and the stated warranty is five years. Those details may appeal if you prefer a simple wired set that can be stored in its own case.
I’d look elsewhere if you specifically want an ear fin or memory-style ear hook, or if inline microphone and track controls are a priority. Those features are not specified for this model. Its listed control is for calls, using a button-style controller.
Piluyaa’s QKZ ENZO puts more emphasis on fit. Each earpiece is listed at 2.3 grams, with a soft ear fin and a memory ear hook designed to wrap around the ear. Three pairs of silicone tips are included, giving you more specified fit options than the LUDOS package. That combination may suit someone who wants the earpieces to stay secure during gaming or other movement.
The USB-C wired connection is intended for compatible Type-C audio devices. Piluyaa also includes an inline microphone and remote buttons for calls and basic playback, including skipping tracks. The remote does not control volume. Its 11 mm dynamic driver and 16-ohm impedance are specified, and the product describes its sound as bright and clear, with bass and treble. Those details describe the design and stated sound profile; they can’t guarantee how it will sound to every listener.
I wouldn’t choose it on the assumption that it blocks outside sound: noise isolation is not specified. And although the fit description mentions working out, no waterproof rating is provided. It should not be treated as waterproof bone conduction headphones for library use—or as waterproof earphones generally.
