If you want wired USB-C headphones for sharing across a classroom or school group, choose WASCLEWAY USB-C Headphones Bulk; if you need a Bluetooth sleep mask for resting in darkness, choose LC-dolida BambooCotton 3D. For flights, I’d pick based on whether you need simple listening for multiple people or a hands-free way to listen while trying to sleep: these products serve very different jobs.
• WASCLEWAY’s biggest strength: a 20-pack of wired, on-ear USB-C headphones with adjustable headbands; trade-off: no wireless connection or noise control.
• LC-dolida’s biggest strength: a Bluetooth sleep mask with a 3D contour designed to leave space around the eyes; trade-off: it is a one-count sleep accessory, not a classroom headphone set.
• Choose WASCLEWAY for shared listening with compatible USB-C devices in classrooms, libraries, or group travel.
• Choose LC-dolida for personal audio during rest, naps, or bedtime when a light-blocking mask is useful.
• Neither is a direct substitute for the other: one is a wired headphone pack, while the other combines a sleep mask and Bluetooth audio.
WASCLEWAY is built around quantity and straightforward compatibility. The package contains 20 wired, on-ear headphones, each with a USB-C connection and a 4.5-foot cable. The adjustable headband and flexible plastic construction make the design suited to a range of users, while the multicolor set may be practical when headphones need to be distributed across a group.
That setup points to schools, testing rooms, libraries, or families with several USB-C devices. The listing names desktops, laptops, Chromebooks, tablets, smartphones, and audio devices as possible companions, though actual compatibility still depends on the device’s USB-C audio support. For flights with children or a group, a set of wired headphones can be a simple option when each listener has a compatible device.
The trade-offs matter. WASCLEWAY is wired, so the cable needs to be managed, and the listed noise control is none. It does not promise active noise cancellation or a battery-powered wireless mode. If your priority is a single personal device for resting, or listening without a cable, this is probably the wrong fit. Despite the travel scenario, it is not a sleep mask and has no listed light-blocking feature.

LC-dolida BambooCotton 3D: Who It's For
LC-dolida combines a sleep mask with wireless Bluetooth audio. Its 3D contour is intended to create space around the eyes, while the adjustable strap is designed to accommodate different head sizes. The product information identifies bamboo-cotton material and a lightweight design. The feature description also presents it as suitable for rest, travel, yoga, and office naps.
That combination could make sense for someone who wants to listen to music, sleep sounds, or podcasts while settling down, rather than wearing conventional on-ear headphones. On a flight, the mask’s light-blocking design may be useful when the goal is to rest. Bluetooth provides a wireless connection, so there is no headphone cable running from the mask to the listening device.
There are important limits to what the listed features establish. The product is a single sleep mask, not a multipack for a classroom or group. The sheet gives no battery-life figure, charging details, noise-cancellation feature, or stated device-compatibility list beyond Bluetooth. If you need a wired USB-C connection, or a headband headphone set for shared use, WASCLEWAY is the more relevant option.
• Best for a classroom or group → WASCLEWAY USB-C Headphones Bulk. It comes as a 20-pack, with a wired USB-C connection on each pair.
• Best for personal rest in darkness → LC-dolida BambooCotton 3D. It is a sleep mask with a 3D contour and a light-blocking design.
• Best for a wired USB-C device → WASCLEWAY. Its connection is USB-C, with a 4.5-foot cable.
• Best for cable-free listening while winding down → LC-dolida. Its built-in Bluetooth is intended for wireless audio.
• Best for adjustable on-ear headphones → WASCLEWAY. The headband adjusts, and the ear placement is listed as on-ear.
• Best for a mask designed with eye space → LC-dolida. Its 3D contour is meant to reduce pressure around the eyes.
• Best for a group flight with compatible devices → WASCLEWAY. Multiple wired sets can serve multiple listeners, but each device needs to support USB-C audio.
• Best for trying to nap during a flight → LC-dolida. The mask’s light-blocking design and Bluetooth audio are aimed at rest, though the sheet does not specify battery life or active noise cancellation.
These aren’t two versions of the same product, so “better” depends on the job. WASCLEWAY’s defining advantage is a group-ready wired format. LC-dolida’s is the combination of a sleep mask and personal wireless audio. A search for the best active noise cancelling Bluetooth earbuds for flights won’t match either product: neither is described as earbuds, and neither lists active noise cancellation.
My Verdict
I’d choose LC-dolida BambooCotton 3D for my own flight-rest use, because its mask design and Bluetooth audio are aimed at listening while trying to sleep.
That is a narrow recommendation, not a claim that it is the better headphone overall.
For classrooms, groups, or shared USB-C devices, I’d choose WASCLEWAY instead.
The deciding question is whether you need a rest-focused mask or a set of wired headphones for several listeners.
For listening as a group with compatible USB-C devices, WASCLEWAY’s 20-pack is the practical match. For personal rest with a light-blocking mask and wireless audio, LC-dolida is the closer fit.
Neither product’s listed features specify active noise cancellation. WASCLEWAY lists no noise control; LC-dolida is described as a sleep mask with Bluetooth audio and light blocking.
WASCLEWAY uses a wired USB-C headphone connection and is listed for a range of USB-C devices. LC-dolida connects wirelessly through Bluetooth, and its product information does not give a specific device-compatibility list.
WASCLEWAY is wired, so it does not rely on a headphone battery according to the listed connection details. LC-dolida’s battery-life figure is not provided, so the available information does not establish how long it can play audio between charges.
