If you want wired, sound-isolating audio for focused streaming and long listening sessions, choose Razer Moray in-Ear Monitor; if you need compact wireless earbuds designed for sleep, choose ZYHKON Sleep Earbuds. For teachers, the Moray makes more sense for planned listening and content work, while the ZYHKON is the more practical fit for bedtime audio and untethered daily use.
Razer Moray in-Ear Monitor vs ZYHKON Sleep Earbuds at a Glance
• Razer Moray’s strength: Its hybrid driver design combines a balanced armature driver and a dynamic driver, with passive noise isolation listed up to -36 dB. Trade-off: It is wired and uses a 3.5 mm jack, so it is not a Bluetooth earbud.
• ZYHKON’s strength: Small wireless earbuds with a sleep mode, a charging case, and up to 48 hours of total playtime. Trade-off: There is no listed noise-control feature, and its small sleep-focused design is not the same as a dedicated sound-isolating monitor.
• For teachers who want a wired listening setup for streaming or focused audio, the Moray is the more relevant pick.
• For listeners who want wireless bedtime audio, side-sleeping comfort, and touch controls, the ZYHKON is the more relevant pick.
The Moray is a wired in-ear monitor built around a hybrid acoustic design. A balanced armature driver handles crisp treble while a dynamic driver supplies bass; a two-way crossover coordinates the two. That setup is intended to deliver a full-range sound suited to extended listening, rather than positioning the product primarily as a sleep accessory. Its listed frequency response reaches 24,000 hertz, with 32-ohm impedance and 106 dB sensitivity.
Its low-profile shape, in-ear fit, and flexible memory-loop tubing on the detachable over-ear wires are useful for someone who wants earbuds held securely and kept out of the way while listening or streaming. Razer includes three sizes of silicone tips and three sizes of memory-foam tips, which gives buyers two kinds of fit material to try. The case is described as splash-resistant, and the product includes passive noise isolation tested up to -36 dB. Those features make the Moray a plausible choice for teachers who want focused audio during preparation, personal streaming, or quiet listening between tasks.

The practical compromise is the cable. The Moray connects through a 3.5 mm jack, so a compatible audio device is required; it is not a wireless option for moving freely around a classroom or taking calls while walking away from a connected device. Who should skip it: Skip the Moray if Bluetooth, a charging case with long total playtime, or a sleep-specific design is your priority.
The ZYHKON earbuds are designed around wireless listening and sleep. Each earbud weighs 3.0 grams, according to the product information, and the ergonomic shape is intended to sit comfortably for side sleepers. A sleep mode turns off low-battery and shutdown alarms, which is a meaningful distinction for someone who wants audio at bedtime without those alerts interrupting sleep. The compact charging box is described as pocketable, so the setup can also travel easily.
For everyday convenience, the ZYHKON offers touch control on the earbuds and a touchscreen charging case. The listed controls include play or pause, volume, track changes, and call answering; the case screen also offers sleep mode, language, wallpaper, and brightness settings. Bluetooth 5.4 provides the wireless connection, and the earbuds list five EQ modes: Standard, Classic, Jazz, Rock, and Pop. A full charge is listed as taking 1.5 hours, with up to 48 hours of total playtime. The figure describes total playtime, not a single uninterrupted listening session.
The audio design uses 13 mm dynamic drivers and an in-ear acoustic structure intended to reduce sound leakage and improve clarity. Calls are included as a use case, but the specification does not identify a noise-control feature. Teachers who want a wireless option for personal listening, commuting, or bedtime may appreciate the convenience; those needing dependable classroom call performance should look closely at the limits of the provided call and noise-control information. Who should skip it: Skip the ZYHKON if you need a wired 3.5 mm connection or specifically want the Moray’s listed passive noise isolation.

My Verdict
I would choose the Razer Moray for focused listening, streaming, and a wired setup with specified passive isolation.
For teachers, I’d pick it for desk-based listening rather than for moving around or sleeping.
I’d choose the ZYHKON instead when wireless freedom, sleep mode, and side-sleeper comfort matter most.
Before choosing, check how you will connect the earbuds. The Moray uses a 3.5 mm jack, which suits compatible audio equipment but rules out the simple cable-free use offered by Bluetooth earbuds. The ZYHKON is wireless and has no headphone jack, so it depends on Bluetooth rather than a wired connection. For a teacher switching between a laptop, phone, and classroom tasks, that distinction may matter more than the driver design.
Think about when and where you will listen, too. The Moray’s over-ear wire and passive isolation suit a more stationary listening session, while the ZYHKON’s stated sleep mode and side-sleeper design point toward bedtime. Neither product’s details establish multipoint pairing, so don’t assume either is multipoint headphones for teachers who want two devices connected at once. Likewise, “clear calls” appears among the ZYHKON’s listed capabilities, but the supplied details do not specify a microphone design or noise reduction for calls. If crystal clear calls sleep headphones for teachers is the goal, treat call performance as a point to verify rather than a guaranteed result.
Finally, separate intended use from labels. The Moray is described for streaming and uses a detachable over-ear cable; it is not specified as a sports earbud. The ZYHKON is wireless and compact, but its feature sheet emphasizes sleep and everyday listening rather than a sports fit or exercise durability. If you are looking for sports earbuds for teachers, neither sheet provides a water-resistance rating or a dedicated sports feature set. The Moray’s splash-resistant case is a detail about its case, not a stated water-resistance rating for the earbuds.
The ZYHKON is the sleep-oriented option. It is described as lightweight, suitable for side sleepers, and includes a sleep mode that turns off low-battery and shutdown alarms. The Moray is designed around wired listening and streaming.
The Moray lists passive noise isolation tested up to -36 dB. The ZYHKON lists no noise-control feature, so its details do not support treating it as a noise-cancelling option.
The ZYHKON listing describes clear calls and includes call answering in its touch controls. The supplied specifications do not give further microphone details or call-noise reduction information, so they do not establish how either product performs in a particular classroom or noisy setting.
Value depends on which features you will actually use. The Moray focuses on hybrid-driver audio, passive isolation, replaceable tip choices, and a wired connection; the ZYHKON focuses on wireless listening, sleep features, touchscreen controls, and up to 48 hours of total playtime.
