Edifier ES850NB Review: Exceptional Battery Life Meets LDAC Wireless Audio
HeadphonesMost people buying ANC wireless headphones have made peace with a routine: charge every night, or every other night at best — because a dead headphone mid-flight or mid-call is a special kind of frustration. The Edifier ES850NB challenges that baseline directly. Its battery reserves sit so far outside the norm for this category that they reframe how you think about owning a wireless headphone entirely. Layered on top of that endurance is LDAC high-resolution wireless audio, active noise cancellation, and a Bluetooth implementation that represents the current state of the standard. Whether this specific combination maps to your actual needs — and where its real limitations land — is exactly what this review unpacks.
Six Numbers That Define the ES850NB
The specification highlights that set this headphone apart before you read further.
Built for the Road, Comfortable at the Desk
At 265 grams, the ES850NB sits within the expected weight range for a full-size ANC over-ear headphone with a substantial battery. The build reflects an adult-oriented ergonomic focus — the over-ear fit distributes clamp pressure around the ear rather than onto it, reducing fatigue during extended sessions in a way that on-ear designs simply cannot match.
The headphones fold flat for transport, and Edifier includes a dedicated carrying case in the box. The folding mechanism makes them compact enough for carry-on luggage without awkward bulging — a practical consideration for the kind of traveler who buys ANC headphones specifically to use while moving.
The cable setup reflects thoughtful engineering: it detaches cleanly and features a tangle-free construction. Detachability means cable damage does not mean headphone damage — you replace the cable only. The tangle-free design means pulling it from a bag pocket does not become a knot-maintenance task every time.
The closed-back design seals the ear cups, preventing sound leakage in both directions. In shared offices, on planes, and in libraries, no one around you hears your audio bleed out — and background sound is physically blocked more effectively than with open-backed designs, before the ANC even activates.
No Water or Sweat Resistance
The ES850NB carries zero moisture protection. Gym use, outdoor exercise, or exposure to rain puts the headphones at genuine risk of damage. These are strictly indoor, dry-environment headphones — home, office, and transit use only.

Audio Quality: Drivers, Codecs, and What Your Device Determines
From the tonal character of the driver technology to the codec that unlocks hi-res wireless quality on your specific device.
The 40mm Driver Character
The 40-millimeter dynamic drivers represent a well-established size in over-ear headphones — capable of genuine bass presence alongside midrange clarity. Larger drivers move more air, contributing to low-frequency impact and output level at a given power input.
The most distinctive aspect is the driver's magnet composition, which differs from the neodymium magnets dominant in modern headphone engineering. This alternative magnet type tends to produce a warmer, smoother tonal character — different from the fast, energetic transient response associated with neodymium-based designs. Listeners who find many modern headphones fatiguing may find this signature genuinely appealing. Those accustomed to a forward, crisp treble will notice the difference. This is a preference matter, not an absolute quality gap, but it makes a listening audition more meaningful for this headphone than most.
Hi-Res Audio Capability
The ES850NB's drivers span from the floor of human hearing to 40,000 Hz — twice the conventional ceiling of auditory perception. This meets the technical threshold for hi-res audio qualification and ensures the drivers operate well within their capability across the full audible spectrum, with no rolloff in the ranges you can actually hear.
Extended high-frequency driver capability also contributes to perceived spatial depth in complex recordings — the sense of "air" audiophiles reference — even without directly perceiving those specific frequencies in isolation.
Wireless Codec: Your Source Device Is the Deciding Factor
LDAC
AndroidSony's high-resolution wireless codec, built natively into Android. Streams at data rates far exceeding standard Bluetooth audio, delivering wireless quality that closely approaches a wired connection. This is the clearest audio benefit the ES850NB offers — and it is Android-exclusive.
AAC
iOS + AndroidApple's preferred wireless codec and the primary connection mode for iPhone users. It delivers solid, capable wireless audio — comparable to what AirPods use — but does not unlock the ES850NB's full hi-res potential. iOS users wanting the best audio quality should use the wired connection.
aptX Family
Not SupportedNo version of Qualcomm's aptX codec is present — not even standard aptX. Buyers specifically expecting aptX HD or aptX Adaptive from Qualcomm-chipset source devices will not find it here. The codec profile deliberately favors LDAC over the entire Qualcomm ecosystem.
Spatial Audio Supported. The ES850NB enables three-dimensional soundstage positioning on compatible content — most noticeable with film, orchestral recordings, and streaming services that output dedicated spatial audio mixes.
ANC Performance, Ambient Mode, and Call Quality
The ES850NB uses microphones to sample ambient noise and generate counteracting signals in real time. For steady, predictable noise environments — airplane cabin pressure, office HVAC systems, train engines — ANC performs well in this product category. For dynamic, irregular sounds like vocal conversations or unpredictable traffic, no ANC system at this tier eliminates them entirely. ANC makes sustained concentration considerably easier; it does not produce silence.
ANC Without Passive Backup
Most closed-back over-ear headphones physically block some noise before ANC activates — the physical enclosure provides a passive first layer. The ES850NB's design places more of the total noise reduction workload on the active system. This makes ANC engagement more critical here than on headphones that layer both approaches. Running ANC off in a loud airplane cabin will be noticeably less comfortable than headphones that combine passive and active isolation.
The ambient sound mode intentionally passes external audio through — announcements, conversations, traffic — without requiring headphone removal. This is the right mode for airport gate listening or street navigation where situational awareness still matters. The same microphone array doubles as a noise-canceling input for voice calls, filtering background room noise to deliver cleaner audio to the person on the other end.

The Feature That Redefines Category Expectations
Approximately three times the industry norm — the single most compelling specification in the ES850NB.
ES850NB vs. the Competition
Competitor figures represent typical published ratings for leading ANC headphones. Real-world performance varies with volume level and usage patterns.
What This Means Day to Day
Bluetooth 5.4, Range, Latency, and Dual Device
Bluetooth 5.4 is among the most current versions of the standard, bringing incremental improvements in connection stability, audio scheduling, and power consumption over the 5.0 and 5.2 implementations found in many competing headphones. The step from 5.2 to 5.4 is evolutionary rather than transformational, but it reflects current engineering rather than a cost-cutting decision on older silicon.
The specified maximum wireless range of 10 meters represents an honest, real-world usable estimate with walls and interference accounted for — not an optimistic open-field test figure. For desk use, couch listening, and commuting, this is consistently sufficient. Walking multiple rooms away from a stationary source device will reach the edge of reliable connection and is not the intended operating pattern.
The 80-millisecond audio delay is typical for Bluetooth wireless audio. For music, podcasts, and audiobooks it is imperceptible. For video content on platforms that handle Bluetooth audio synchronization it remains within acceptable lip-sync tolerance. For gaming where audio cues are timing-critical, this delay is noticeable — the wired connection fully resolves this by bypassing Bluetooth entirely.
Dual Device Connection in Practice
The ES850NB connects to two devices simultaneously. In practice: your work laptop and personal phone are live at once. An incoming call on the phone interrupts laptop audio cleanly, without manual reconnection. Initial Bluetooth pairing is conventional setup — there is no Google Fast Pair shortcut or NFC-tap option. This is a one-time inconvenience per device, not a recurring friction point.

Strengths and Limitations Stated Plainly
Where the ES850NB Excels
-
Battery Endurance That Changes the Ownership Experience92 hours without ANC is not a marketing figure that collapses in real use. It is the single most compelling reason to choose the ES850NB over any directly comparable product — and nothing in this feature tier matches it.
-
LDAC at This Battery Level Is a Rare CombinationHigh-resolution wireless audio on a headphone that charges every two weeks does not exist in many competing products at this tier. For Android users, this is a genuine differentiator.
-
Genuinely Travel-Ready BuildFoldable design, included case, and a detachable tangle-free cable are the details of a headphone built for people who actually travel — not one that nominally supports it.
-
Current Bluetooth with Dual Device ConnectionVersion 5.4 and simultaneous two-device connection reflect current-generation engineering. Keeping a laptop and phone connected at once without manual switching is genuinely practical.
-
Extended Frequency Response Without StrainThe wide driver frequency range means no rolloff within the audible spectrum. The result is an effortless, non-fatiguing sound presentation that suits long listening sessions.
Where the ES850NB Compromises
-
The Driver Tonal Character Requires an Open MindThe non-neodymium magnet design produces a warmer, smoother signature than most modern headphones. Listeners expecting bright, punchy treble reproduction may need to adjust expectations. This is a sonic difference, not an absolute quality gap.
-
No Hardware Mute Is a Real Gap for Office UsersProfessionals in heavy video conferencing will feel this omission. Software muting works, but the extra steps accumulate meaningfully across many hours of daily calls.
-
ANC Carries the Full Noise Reduction WorkloadWithout passive isolation as a backup layer, the ANC must be engaged in loud environments. Running it off on a plane or in a loud office is noticeably less comfortable than on headphones that combine both approaches.
-
Conservative Bluetooth RangeThe 10-meter specification is honestly stated but shorter than many competitors claim. Walking from one room to an adjacent one with a stationary source device will test the connection limit.
-
No aptX Codec SupportThe entire Qualcomm aptX ecosystem is absent. Buyers expecting these codecs from Qualcomm-chipset source devices will not find them — and iOS users miss out on LDAC entirely, limiting their wireless audio ceiling to AAC.

A clear-eyed purchase verdict based on everything this headphone does well and where it falls short.
The Bottom Line
The Edifier ES850NB answers a question headphone buyers have quietly asked for years: why do ANC wireless headphones with premium features still need charging every few days? The battery reserves here sit so far outside the category norm that, once experienced, everything else feels like planned obsolescence. Paired with LDAC for Android users and a Bluetooth 5.4 implementation that handles dual device connection cleanly, this is a headphone built around a coherent and practical set of priorities executed with genuine conviction.
It is not a headphone for every buyer. Those requiring maximum ANC precision, iOS-optimized hi-res wireless audio, or the convenience refinements of premium flagships will find better-optimized options elsewhere. But for the traveler who wants to stop thinking about charging cables, the remote worker who needs wireless audio that outlasts any workweek, or the Android audiophile who wants LDAC without compromise — the ES850NB makes a confident and well-reasoned case for itself.
