Black Shark Fengming S1 Review: The Over-Ear Built to Last
HeadphonesBlack Shark has spent years building gaming peripherals that punch above their price class, and the Fengming S1 is the brand's statement entry into wireless over-ear headphones. This is not a gaming headset with a boom mic bolted onto a cheap plastic shell — it is a full-featured wireless headphone with active noise cancellation, a genuinely impressive battery story, and a design flexible enough for the commute, the desk, and everything in between. The question worth answering before you spend your money: does it actually deliver, or is "Black Shark" just a name printed on the box?
Design and Build: Practical Decisions, Not Premium Theater
The Fengming S1 takes an over-ear form factor — the earcups fully enclose your ears rather than resting on them. For most people, this translates to better passive isolation and more comfort over long sessions compared to on-ear designs that press directly against the ear itself.
The headphone folds flat, which matters more than it sounds. A headphone that cannot fold is a headphone that lives on your desk and rarely travels. The Fengming S1's collapsible structure means it fits into a bag without drama, making it a realistic daily companion for people who actually move around.
The cable situation is handled thoughtfully. The included cable runs 1.2 meters — long enough for desktop use without becoming a tripping hazard — and it detaches completely. A tangle-free design means you are not arriving somewhere with a knotted mess. Detachability also matters for longevity: if the cable wears out, you replace the cable, not the headphone.
The closed-back construction keeps sound inside the cups and outside noise out. This is the right call for a headphone positioning itself around noise cancellation. Open-back designs offer a more airy sound but sacrifice isolation — a trade-off that makes little sense in a product built for real-world mixed-environment use.
Sound Quality: The 40mm Driver Story
Three pillars define the Fengming S1's acoustic profile — driver size, frequency coverage, and spatial processing.
Driver Size in Context
The Fengming S1 uses 40mm drivers — the transducers responsible for converting electrical signals into sound. In over-ear headphones, 40mm is a well-established size that sits comfortably in the mainstream category. It is large enough to produce authoritative low-end response and clear midrange without the engineering compromises that come with miniaturized drivers in earbuds. Driver tuning matters far more than raw size, but 40mm is a credible foundation to build on.
Full-Range Frequency Response
The headphone covers the complete range of human hearing — from sub-bass frequencies you feel in your chest during an action film or electronic music, up to the fine details in cymbals, string overtones, and vocal air at the upper limit of perception. No artificial cuts are applied anywhere in the frequency range. This is standard for the category, but it confirms nothing has been stripped away to cut corners.
Spatial Audio Support
The Fengming S1 supports spatial audio — a processing technique that creates a sense of three-dimensional sound from a standard stereo source. For gaming, this translates to directional awareness: footsteps to the left, gunfire from above. For film, it creates a cinematic sense of space. Implementation quality varies by platform and source, but the hardware capability is fully present.
Active Noise Cancellation and the Microphone Array
Five Microphones, Two Roles
The Fengming S1 carries five microphones, and they serve two distinct purposes. Some handle the call and voice pickup function — feeding your voice to whoever you are speaking with. Others are part of the ANC system, sampling ambient sound so the headphone can generate opposing audio signals that cancel noise before it reaches your ears.
Five microphones is a meaningful number for this price tier. Entry-level headphones with ANC typically manage with two or three. More microphone positions allow the system to sample noise from multiple angles, improving cancellation across different noise profiles — a consistent office hum, variable traffic noise, or the chaotic audio environment of public transit.
Ambient Sound Mode
When you need to be aware of your environment without removing the headphones, ambient sound mode pipes in external audio through the microphones. This is useful at a coffee counter, during a quick conversation, or when situational awareness matters. It functions as the practical opposite of ANC — instead of blocking the world, it lets it in on demand.
Microphone Quality for Calls
The noise-canceling microphone array doubles for voice calls and video meetings. Five microphones with noise-canceling processing in the pickup chain is a solid specification for call clarity. Background noise suppression during calls is handled by the same hardware that powers the ANC system — a meaningful advantage over headphones that treat call microphones as an afterthought.
Battery Life: The Category-Leading Number That Needs Unpacking
155 Hours Without ANC — What That Actually Means
155 hours of wireless playback without ANC active is one of the highest figures in this segment. If you use these headphones for three hours a day, every single day, you would go nearly seven weeks between charges. For a typical user who wears headphones two to four hours daily, monthly charging becomes a realistic expectation rather than a weekly chore.
This is made possible by an internal battery substantially larger than what most over-ear headphones use. Many competitors in this category achieve 30–60 hours of wireless playback. The Fengming S1's cell is nearly double that norm — a capacity that reshapes how you think about ownership.
80 Hours With ANC Enabled
Active noise cancellation draws power from the same battery, reducing endurance to 80 hours. That is still exceptional — most ANC headphones in this range deliver 20–40 hours with noise cancellation running. Even power users who keep ANC on continuously would realistically get three to four weeks per charge before needing a cable.
Charging is handled via USB-C, the universal standard. A battery level indicator lets you check remaining charge without guessing. There is no wireless charging — but given the endurance figures, that absence is easy to accept. You will not be reaching for a cable often enough for it to matter.
Battery Life Compared to Category Norms
Connectivity: Bluetooth 6 and the Wired Fallback
Bluetooth 6 — A Genuine Upgrade
The Fengming S1 uses Bluetooth 6, the newest generation of the wireless standard. Bluetooth 6 improves connection stability, introduces channel sounding for more precise proximity behavior, and reduces the overhead that older versions carried. In practice, this means a more reliable connection and less susceptibility to dropout in congested wireless environments like offices or busy transit hubs.
Latency and Range
Wireless audio latency sits at 60 milliseconds. For music and podcasts, this is completely irrelevant. For video calls, it falls within acceptable range and will not feel perceptibly out of sync. For competitive gaming where sub-30ms synchronization matters for reaction-critical audio cues, the wired connection eliminates latency entirely. The Bluetooth range reaches 10 meters — standard for this class and sufficient for most home and office use.
Codec Support: AAC Only
The wireless audio codec picture requires honest discussion. The Fengming S1 supports AAC but not aptX, LDAC, LHDC, or LE Audio. AAC is the codec used natively by Apple devices and delivers good wireless audio quality for the majority of listeners streaming from Spotify, Apple Music, or YouTube — the AAC ceiling is one most people will never reach.
For audiophiles who have invested in LDAC-capable sources and high-resolution audio libraries, this is a real limitation. The AAC-only wireless chain caps the fidelity available regardless of source quality. It is a deliberate positioning decision, and informed buyers deserve to know it exists.
Who Should Buy This — and Who Should Not
The Fengming S1 is a strong product for a specific type of buyer. Knowing which side of this line you fall on is the most important purchase decision.
- Commuters and travelers who want ANC that outlasts any flight or daily transit routine without battery anxiety.
- Work-from-home professionals who need call quality, ambient mode, and all-day comfort without a charging interruption.
- Casual to mid-level listeners who want full-range sound and spatial audio for music, films, and casual gaming.
- Apple ecosystem users where AAC codec support is native and delivers its best possible performance.
- People who travel light and need a foldable headphone that genuinely fits in a bag without a dedicated case.
- Audiophiles who require LDAC or aptX HD for lossless wireless transmission — the AAC-only chain is a ceiling they will genuinely feel.
- Competitive gamers requiring ultra-low wireless latency — 60ms is capable for casual play but falls short of dedicated gaming headset standards.
- Heavy video call users who need a device-side mute button — muting requires reaching for the connected device each time.
- Buyers who prioritize premium tactile materials and luxury brand prestige — Black Shark's identity is performance value, not tactile luxury.
How It Compares to the Competition
The Fengming S1's most dramatic competitive advantage is battery endurance — it is not a marginal lead. It is a category-redefining gap. The trade-off is codec depth, where mid-range competitors frequently offer LDAC or aptX HD.

Strengths and Honest Weaknesses
Where It Excels
The Fengming S1's battery life is not just a selling point — it is a genuine shift in how you interact with a headphone. Charging becomes an event that happens occasionally rather than a background anxiety that follows you through every week. That shift has real quality-of-life value that does not always appear on comparison charts, but you feel it every day you pick these up without checking the charge level.
The five-microphone array is a meaningfully generous implementation. Call quality and ANC effectiveness both benefit from microphone count, and the Fengming S1's hardware investment here shows Black Shark took audio input as seriously as audio output.
Bluetooth 6 is forward-looking. As devices adopt the standard, the stability and efficiency benefits will become more apparent. Buying the newest wireless generation now is a small hedge against early obsolescence that most competitors at this tier are not offering yet.
Where It Shows Its Limits
The AAC-only wireless chain is a deliberate positioning decision — it keeps complexity and cost lower while satisfying the majority of users. But it is a ceiling, and informed buyers deserve to know it exists. Audiophiles and high-resolution audio enthusiasts will feel it; casual streamers almost certainly will not.
The lack of a device-side mute button is a workflow friction point that will be invisible to casual users and mildly annoying to anyone who takes frequent video calls. It is the kind of omission that only surfaces in real daily use — not in a spec comparison.
No NFC or Fast Pair means a marginally slower initial pairing experience. And while the large internal battery is a key advantage, it almost certainly means a longer wait to top up from empty — expect to plan around a lengthier charging window when the day finally comes.
Questions Real Buyers Ask Before Purchasing
Final Verdict
The Black Shark Fengming S1 solves the problem that bothers the largest number of wireless headphone owners: you forget to charge it, and it dies. With 155 hours of wireless endurance and 80 hours with ANC running, that problem effectively disappears for most people. Paired with Bluetooth 6, a five-microphone system, spatial audio, ambient sound mode, and a design that folds and travels without complaint, this is a genuinely well-considered package.
The AAC-only wireless chain is a real ceiling that audiophiles and high-resolution listeners will feel. The absence of a device-side mute button and fast-pairing convenience features are genuine omissions that belong in the balance sheet. But for the pragmatic listener, these are trade-offs made in the right direction.
For the pragmatic listener who values endurance and versatility over audiophile wireless credentials, the Fengming S1 makes a compelling, confident case. If you are chasing the best possible wireless fidelity, your budget is better spent elsewhere — but most buyers are not, and most buyers will not be disappointed.
