How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want compact, cable-free earbuds with active noise cancellation for commutes, workouts and calls, choose EarFun Air Pro 3; if you need over-ear planar magnetic headphones with wired and wireless flexibility plus marathon battery life for long listening sessions, choose Amazon Renewed Edifier STAX Spirit.
• EarFun Air Pro 3 — biggest strength: Hybrid ANC rated to cut noise by up to 43dB, six ENC mics with Qualcomm cVc 8.0, and a pocketable in-ear design. Biggest trade-off: 8 hours per charge means you'll rely on the charging case for all-day use.
• Amazon Renewed Edifier STAX Spirit — biggest strength: Planar magnetic drivers, up to 80 hours of playback, and USB-C plus 3.5mm wired options alongside Bluetooth 5.4. Biggest trade-off: It's a Renewed over-ear unit with a 90-day limited warranty, and it isn't the grab-and-go form factor earbuds are.
• Pick EarFun Air Pro 3 if you want true wireless earbuds for the gym, the train and phone calls.
• Pick Amazon Renewed Edifier STAX Spirit if you want a desk-and-couch headphone for critical listening, and you're comfortable buying refurbished.
The EarFun Air Pro 3 is built around Qualcomm's QCC3071 chipset with aptX Adaptive Audio, driving 11mm wool composite dynamic drivers. In plain terms: this is a true wireless earbud tuned to keep bass present and voices clean while resisting distortion when the music gets loud. The frequency range runs 20Hz to 20,000Hz, so it covers the full audible spread you'd expect from a mainstream in-ear.
The noise cancelling is the headline. EarFun's QuietSmart 2.0 hybrid ANC is rated to reduce environmental noise by up to 43dB, and you can switch modes depending on whether you're on a plane, a train platform or just trying to focus at a desk. For calls, six microphones work with Qualcomm cVc 8.0 ENC to pull your voice forward and push background and wind noise back. If you spend a lot of time on voice calls from noisy places, that's the spec to care about.
Battery life is 8 hours per charge, with the charging case adding more — and the case itself takes about 2 hours to top up. The buds charge in roughly an hour. Bluetooth 5.3 with multipoint means you can stay connected to two devices at once, so a work laptop and a phone can both be live without constant re-pairing. Latency is listed at 55ms, which is reasonable for casual gaming and video. The earbuds are in-ear with a rounded tip in black plastic, controlled by touch, and the case weighs 18g — small enough to disappear in a pocket.
Who should buy it: anyone who wants one pair of earbuds for commuting, workouts, calls and everyday streaming, and who values ANC and multipoint over audiophile codecs.
Who should skip it: if you want over-ear comfort for six-hour listening sessions, wired USB-C or 3.5mm connections, or the specific character of a planar magnetic driver, this isn't the product for you.
The Edifier STAX Spirit S5 is a different category of product entirely. It's an over-ear, closed-back headphone built around planar magnetic drivers with Edifier's EqualMass diaphragm, which is designed to apply uniform driving force across the surface for low distortion and fast response. The practical result of that design is detail and speed — the kind of presentation people reach for when they want to hear how a recording is put together rather than just feel the low end.
The wireless side is serious. It runs Qualcomm's QCC5181 platform with Snapdragon Sound, and supports LDAC, LHDC, aptX HD, aptX Adaptive and aptX Lossless. Hi-Res Audio and Hi-Res Audio Wireless are both supported, with aptX Adaptive holding up to 24-bit/96kHz at roughly 89ms end-to-end latency. Bluetooth 5.4 adds Google Fast Pair and simultaneous connection to two devices. Wired listeners aren't left out either: there's both USB-C and a 3.5mm AUX cable, so you can bypass Bluetooth entirely when you want to.
Battery is the standout number: up to 80 hours of playback per charge, and a 10-minute top-up is rated to give you 11 hours. For anyone who hates charging rituals, that changes the ownership experience — you charge it occasionally rather than nightly. Calls use dual mics with Qualcomm cVc, and the closed-back design keeps your audio private. Comfort comes from an adjustable headband and genuine lambskin earpads, and the foldable structure plus carry case make it travel-friendly. The EDIFIER ConneX app adds three preset EQ modes and custom EQ. Impedance is 32 ohm and the frequency range is 40Hz to 20kHz.
There is one thing to be clear-eyed about: this is a Renewed listing, and it carries a 90-day limited warranty rather than a full manufacturer term. That's the trade-off for buying refurbished.
Who should buy it: listeners who want a planar magnetic over-ear for home, office and travel, who value long battery life and wired fallback, and who are comfortable with a Renewed purchase and its shorter warranty.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling on the move → EarFun Air Pro 3. Up to 43dB of hybrid ANC in a sealed in-ear fit is the more effective combination for commuting and flights.
• Best for battery life → Amazon Renewed Edifier STAX Spirit. Up to 80 hours per charge versus 8 hours for the EarFun buds. It isn't close.
• Best for calls in noisy places → EarFun Air Pro 3. Six ENC mics with cVc 8.0 are purpose-built for voice pickup; the S5 uses a dual-mic setup.
• Best for sound quality and detail → Amazon Renewed Edifier STAX Spirit. Planar magnetic drivers with LDAC, LHDC and aptX Lossless support are a step up in resolution and codec support.
• Best for workouts and commuting → EarFun Air Pro 3. In-ear, 18g case, touch controls, nothing to fold or pack.
• Best for desk and couch listening → Amazon Renewed Edifier STAX Spirit. Over-ear lambskin comfort plus USB-C and 3.5mm wired options for zero-latency listening.
• Best for latency-sensitive gaming → EarFun Air Pro 3 on paper. 55ms is lower than the S5's 89ms, though the S5 can go fully wired via USB-C or AUX to sidestep wireless latency altogether.
• Best for low-hassle ownership → EarFun Air Pro 3. A new product with the standard warranty beats a Renewed unit with a 90-day limited warranty if peace of mind matters most.
In my opinion, these two aren't really competitors — they solve different problems, so the honest answer is to buy the one that matches your life. If you want a single pair of earbuds to cover commuting, calls and workouts with real ANC, I'd buy the EarFun Air Pro 3. If you want a serious over-ear for long home listening sessions, with planar magnetic drivers, wired options and battery you barely think about, I'd buy the Amazon Renewed Edifier STAX Spirit — accepting the Renewed warranty as part of the deal. For most people reading this, the EarFun is the safer everyday pick.
For blocking noise in real-world environments, yes, in my opinion — the EarFun's hybrid ANC is rated up to 43dB and the in-ear seal adds passive isolation. The S5 has ANC too, but an over-ear fit and its tuning are aimed more at sound quality than maximum noise reduction.
Up to 80 hours per charge for the S5 versus 8 hours for the EarFun buds. The EarFun's charging case extends total listening time, but it still needs more frequent charging overall. The S5 also gets 11 hours from a 10-minute top-up.
It's a legitimate way to buy, but know what you're getting: a 90-day limited warranty instead of a full-length one. If that shorter coverage bothers you, the new EarFun Air Pro 3 is the lower-risk purchase.
Yes. It includes both a USB-C cable and a 3.5mm AUX cable, so you can connect to phones, laptops, consoles and audio gear directly — useful when you want no wireless latency at all.
