If you want stronger stated noise cancellation, longer battery life, and a volume limit for school, choose Edifier W820NB; if you need a foldable over-ear option with dual-device connection, choose Edifier W800BT. For students who want one headset to handle lessons, study sessions, and calls, I’d lean toward the W820NB because its volume guard and longer listed playback time are practical advantages.
Edifier W820NB vs Edifier W800BT at a Glance
• Edifier W820NB: Stronger stated ANC depth at -49 dB, volume guard, and up to 88 hours of playback with ANC off; trade-off: its listed playback falls to 49 hours with ANC on.
• Edifier W800BT: Dual-device Bluetooth connection, hybrid ANC, and up to 45 hours of playback with ANC off; trade-off: its listed ANC depth is -44 dB, and it has no volume-guard feature listed.
• Choose the W820NB if battery endurance, a volume cap, and spatial sound matter most.
• Choose the W800BT if switching between two connected devices is a priority.
• Both are over-ear, foldable Bluetooth headphones with 40 mm dynamic drivers and AI-assisted call-noise reduction.
The W820NB’s standout combination is active noise cancellation, a volume guard, and a long stated battery life. Its ANC is rated at up to -49 dB, and the product offers multiple ANC modes that can be switched using physical buttons. The EDIFIER ConneX app adds customization, including scenario-oriented modes and EQ presets. Spatial sound is another listed feature, though whether you enjoy that presentation is a matter of taste.

For school, the volume guard is the feature I’d pay close attention to. It lets you set a preferred maximum listening level, which can be useful when moving between quiet study and noisier surroundings. It is not a substitute for making careful listening choices, but it gives you a way to set a ceiling rather than relying only on moment-to-moment judgment. That makes the W820NB a strong candidate for someone searching for the best volume limiting headset for school.
Battery claims are also compelling, with up to 88 hours of use without ANC and 49 hours with it enabled. Fast charging is specified as 15 hours of playback from a 15-minute charge. The trade-off is that the longer figure applies with ANC off, so the mode you use affects endurance. Skip this model if connecting to two devices simultaneously is essential: that feature is listed for the W800BT, not the W820NB.
The W800BT Pro is the more straightforward pick if you regularly move between two Bluetooth audio sources. It can stay connected to two devices at once, which could suit a student who wants to switch between a laptop and phone without repeatedly pairing. Its Bluetooth version is 5.4, and the headphones also include app support for personalized controls and EQ presets.
Its hybrid ANC is specified at up to -44 dB, while playback is listed at up to 45 hours with ANC off. A 10-minute charge is said to provide up to eight hours of use. That is useful for a quick top-up, but the total stated battery life is shorter than the W820NB’s, and the two models’ charging claims are not identical measures. I would not treat those figures as a direct charging-speed test.
The W800BT is also foldable and designed as an over-ear headphone, with a lightweight build, pressure-relief headband, and soft ear pads described in its product information. Those details make it worth considering for longer study blocks, although comfort is personal and fit varies. If your priority is a dedicated volume maximum, or the longest stated battery life, the W820NB is the more suitable choice based on the listed features.
• Best for setting a listening ceiling → Edifier W820NB. Its volume guard lets you set a preferred maximum level; the W800BT does not list an equivalent feature.
• Best for longer stated battery life → Edifier W820NB. It lists up to 88 hours with ANC off and 49 hours with ANC on, compared with up to 45 hours for the W800BT with ANC off.
• Best for stronger stated ANC depth → Edifier W820NB. Its listed figure is up to -49 dB, versus up to -44 dB for the W800BT. Those numbers alone do not tell you exactly how either model will sound in every environment.
• Best for switching between a phone and laptop → Edifier W800BT. It supports simultaneous connection to two Bluetooth devices.
• Best for spatial sound → Edifier W820NB. Spatial sound is explicitly listed, alongside app-based EQ customization.
• Best for a quick charging top-up → Edifier W820NB, on the stated figures. It lists 15 hours of playback after 15 minutes of charging; the W800BT lists eight hours after 10 minutes. These are manufacturer figures, not a controlled head-to-head comparison.
• Best for AI-assisted calls → Tie on the listed feature. Both describe AI noise reduction intended to help keep voices clear during hands-free calls.
• Best rotatable ear cups over ear headphones for school → Neither is a confirmed match from the listed details. Both are foldable over-ear models, but rotatable ear cups are not specified for either one.
I’d choose the Edifier W820NB for school because its volume guard, longer stated battery life, and stronger stated ANC depth make it the more useful all-round fit for classes and study sessions. The W800BT is the better match if two-device connection is a must.
I would not pick either solely as the best deep bass gaming headset for school: the available feature details do not establish that either has a particular bass profile or gaming-focused features. For my school-focused recommendation, the W820NB is the clearer choice.
For a student who values a volume limit and longer stated battery life, I’d choose the W820NB. The W800BT may suit you better if you need to connect two Bluetooth devices at once.
The W820NB lists ANC up to -49 dB, while the W800BT lists hybrid ANC up to -44 dB. That specification gives the W820NB the higher stated noise-reduction depth, but it does not guarantee how much sound you will notice in a particular setting.
The W800BT explicitly supports simultaneous connection to two Bluetooth audio devices. The W820NB’s listed features do not specify dual-device connection.
The W820NB lists up to 88 hours with ANC off and 49 hours with ANC on. The W800BT lists up to 45 hours with ANC off, so compare the ANC-off figures as stated and remember that actual playback time can depend on use.
