How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want earbuds with true wireless freedom, active noise cancellation and a water-resistant build for the gym and the commute, choose Edifier NeoBuds Planar TWS; if you need maximum battery life, wired backup options and a full-size planar magnetic over-ear for long listening sessions, choose Amazon Renewed Edifier STAX Spirit.
• Edifier NeoBuds Planar TWS — biggest strength: a genuinely modern in-ear package: 12mm planar magnetic drivers, hybrid adaptive ANC rated to cut up to 40dB, LDAC/LHDC 5.0 and aptX Lossless over Snapdragon Sound, plus IP55 resistance.
• Edifier NeoBuds Planar TWS — biggest trade-off: 30 hours of total playtime is respectable for earbuds but far below the over-ear alternative, and the tiny drivers simply can't move air the way a full-size planar can.
• Amazon Renewed Edifier STAX Spirit — biggest strength: up to 80 hours of playback, a 10-minute charge that yields 11 hours, and a large planar magnetic driver with the second-gen EqualMass structure in a closed-back over-ear design.
• Amazon Renewed Edifier STAX Spirit — biggest trade-off: it's a renewed unit with a 90-day limited warranty, it's bulky compared to earbuds, and it has no IP rating for sweat or rain.
• Who each is for: pick the NeoBuds if portability, ANC and workout-friendly durability matter most; pick the STAX Spirit if you want marathon battery life, wired USB-C/AUX flexibility and big-driver sound at home or at a desk.
The NeoBuds Planar TWS is the more "everyday life" product of the two. It's a true wireless earbud built around a 12mm planar magnetic driver with a 2μm ultra-thin diaphragm and second-gen EqualMass wiring — the same planar principle as the over-ear, just shrunk into your ear. On the wireless side it's unusually well equipped: LDAC and LHDC 5.0 plus aptX Lossless via Snapdragon Sound, which means 96kHz/24bit audio can survive the trip from a compatible phone to your ears. The third-gen Qualcomm adaptive ANC is rated to block up to 40dB and adjusts to whatever room or train carriage you're in, and a six-microphone array with aptX Voice handles calls.
What makes it genuinely practical is everything around the sound. IP55 resistance covers sweat and light rain, wear detection auto-plays and pauses when you take a bud out, Bluetooth 5.4 multipoint lets you hop between laptop and phone, and a 60ms low-latency mode is there for gaming. The case adds up to 30 hours total, and a 10-minute top-up buys about 2 hours of listening. The Edifier ConneX app handles EQ, ANC modes and control remapping.
Buy it if you want one pair for the gym, the bus and the desk, and you value ANC and water resistance over raw stamina. Skip it if you mostly listen at home for hours at a stretch, or if you want the option of a cable — there's no wired mode here, and 30 hours total is the ceiling.
The Amazon Renewed Edifier STAX Spirit is a different animal entirely: a closed-back, over-ear planar magnetic headphone with a 32-ohm impedance and a 40Hz–20kHz range, running on the Qualcomm QCC5181 platform with the full Snapdragon Sound suite — LDAC, LHDC, aptX HD, aptX Adaptive and aptX Lossless. That last one is the codec I'd point at first: aptX Adaptive keeps high-resolution audio up to 24-bit/96kHz with end-to-end latency of just 89ms, which is why this pair works as well for video and gaming as it does for music. Two Bluetooth 5.4 connections can be held at once, and Google Fast Pair speeds up Android pairing.
The headline number, though, is battery: up to 80 hours per charge, with a 10-minute charge giving you 11 hours. If you've ever babysat a dying earbud on a long flight, that spec alone changes how you use the product. Add USB-C and 3.5mm AUX cables and you can plug into a laptop, DAC or in-flight system when wireless isn't an option — something the NeoBuds simply can't do. Comfort is handled with adjustable headbands and genuine lambskin earpads, the closed-back design keeps your music private, and the foldable frame plus carry case make it travel-ready. Dual mics with Qualcomm cVc handle calls, and the Edifier ConneX app offers three preset EQs plus custom tuning.
Buy it if you want a full-size planar for long sessions, wired flexibility and huge battery life, and you're comfortable with a renewed unit backed by a 90-day limited warranty. Skip it if you need something pocketable, sweat-proof, or with active noise cancellation — this is an on-ear/over-ear design with a closed back, not an ANC travel headphone.
• Best for total playtime → Amazon Renewed Edifier STAX Spirit (up to 80 hours vs 30 hours total).
• Best for noise cancellation → Edifier NeoBuds Planar TWS (hybrid adaptive ANC rated up to 40dB; the STAX Spirit's noise control listed is active noise cancellation but it's a closed-back over-ear, not a dedicated ANC travel design).
• Best for workouts and weather → Edifier NeoBuds Planar TWS (IP55; the STAX Spirit has no IP rating).
• Best for wired listening → Amazon Renewed Edifier STAX Spirit (USB-C and 3.5mm AUX cables; the NeoBuds are wireless only).
• Best for low-latency gaming and video → Amazon Renewed Edifier STAX Spirit (89ms end-to-end with aptX Adaptive) — though the NeoBuds' 60ms gaming mode is competitive for in-ear use.
• Best for portability → Edifier NeoBuds Planar TWS (62g total, charging case, pockets easily).
• Best for long, comfortable home sessions → Amazon Renewed Edifier STAX Spirit (lambskin earpads, adjustable headband, foldable with carry case).
• Best for buyers who want a factory-fresh unit → Edifier NeoBuds Planar TWS; the STAX Spirit is a renewed product with a 90-day limited warranty.
In my opinion, the Amazon Renewed Edifier STAX Spirit wins on raw capability: 80 hours of playback, aptX Adaptive with 89ms latency, USB-C and AUX inputs, and a large planar driver make it the more complete listening tool. I'd buy it if music is something I sit down for. But I'd buy the Edifier NeoBuds Planar TWS without hesitation if my listening happens on the move — ANC, IP55 and a 62g charging case are things the over-ear simply can't offer. Check the current price on Amazon for both before you decide, since that's the one variable that can flip this call.
FAQ
what is aptx adaptive headphones
Both products lean on Snapdragon Sound for their best codecs. The NeoBuds Planar TWS use LDAC/LHDC 5.0 and aptX Lossless over Snapdragon Sound for 96kHz/24bit audio, and the STAX Spirit supports LDAC, LHDC, aptX HD, aptX Adaptive and aptX Lossless. A non-Snapdragon phone still works over standard Bluetooth, but you won't get the top-tier codecs.
Yes — IP55 resistance covers sweat and light rain, and wear detection pauses playback when you pull a bud out. The 12mm planar drivers and hybrid ANC rated up to 40dB are also well suited to noisy gyms and commutes, and 30 hours total playtime covers a week of sessions.
The renewed listing carries a 90-day limited warranty, which is the main thing to weigh. What you get is the same hardware: planar magnetic drivers with EqualMass wiring, Snapdragon Sound with aptX Adaptive, up to 80 hours of playback, and USB-C plus 3.5mm AUX connectivity — just in renewed condition rather than factory new.
