Edifier TWS1 Pro 2: problems, parts and running costs

Checked: 2026-10-05

Summary

What owners and testers report most is sound, not hardware: the earbuds are SBC-only with no AAC and the upper frequencies come out harsh and distorted, which no setting fully removes. Second is battery, at roughly four and a half hours per charge with noise cancelling on against a 4-hour claim, and third is microphone behaviour on calls outdoors. There are no consumables and no subscriptions, so the yearly running cost is effectively nothing; the pair is worth buying at or below the $49.99 launch price, above all for gym and commuting use. [1][2][3]

Common problems and fixes

Harsh, distorted upper frequencies from the SBC-only codec — the most repeated criticism, carried by two r/Earbuds threads, HeadphonesAddict’s measurements, SoundGuys and Major HiFi. HeadphonesAddict measured a treble peak near 6.5 kHz, a dip at 10 kHz and little energy above 11-12 kHz; SoundGuys describes a 5-8 kHz boost that can turn painful on percussion at high volume. It is a design limitation, not a defect, so warranty does not cover it. Workaround: ANC off with the Classical preset, the configuration HeadphonesAddict recommends. [1][2][4][9][10]
Battery runs out mid-session with ANC on — two independent tests measured 4 h 40 min and 4 h 51 min with ANC on against Edifier’s 4 h claim, and Scarbir calls the ANC-on runtime the elephant in the room, roughly 1-2 hours short of nearly every rival at this price. Both labs and Scarbir list battery as the weak point. Workaround: 10 minutes in the case adds an hour, and without ANC the earbuds run 6 h with the case adding 18 h more. Gradual capacity loss is not treated as a consumable; only defects inside the one-year term are covered. [1][2][3][6][7]
Microphone unusable outdoors and in wind — Scarbir finds calls clear and easy indoors but almost undoable outdoors because wind noise takes the voice over, and notes that surrounding voices still come through clearly on a call; HeadphonesAddict heard audible distortion near a busy road; SoundGuys’ reader poll on the microphones is bottom-weighted, with 29% rating them awful or bad and 5% perfect. Workaround: take calls somewhere sheltered. A dead or crackling microphone is a warranty matter, ordinary outdoor pickup is not. [1][2][3]
No volume control from the earbuds — only double and triple taps are assignable and single tap cannot be used, so the available slots go to ANC cycling and track changes; HeadphonesAddict notes the remaining volume action works from one side only. Workaround: change volume on the phone. Not a fault, and not a warranty item. [2][3]
No multipoint and no AAC — the earbuds cannot hold two devices at once, and the only codec is SBC. This is the stated reason Scarbir cut its own score in April 2025, arguing the category had moved past the model. Workaround: disconnect and re-pair each time you switch devices. [1][2][3]
Audio lag in games even with game mode on — HeadphonesAddict found visible latency remaining in mobile games with game mode enabled and rated it suitable only for casual play. No fix is offered; serious players need separate audio gear. [2]
Case scuffs, holds fingerprints, and the black one disappears in a bag — HeadphonesAddict notes the glossy plastic scratches easily and that the black case is hard to find in a backpack, and found the pairing and reset button hard to locate on the glossy finish; The Gadgeteer independently calls the case a fingerprint magnet. Workaround: keep the case in a pouch. Cosmetic wear is not a warranty item. [2][5]
One earbud can go dead — a single owner report describes a right earbud that shows offline in the Edifier Connect app and produces no sound across multiple devices, with the usual fixes failing. It is one unresolved report, not a failure rate. With no spare earbud sold, the only route is a warranty replacement inside the one-year term. [3][7][8][11]

Parts and consumables

No replacement parts or consumables were found for this model.

Silicone ear tips (four pairs, XS/S/M/L, in the box) — the only wear item, and Edifier sells no replacement tips for the TWS1 Pro 2. The support page offers only the user manual, the EU declaration of conformity and the app download, so replacement tips have to come from a third party. [2][8]
Earbud assemblies — not sold, and replacing a single failed earbud is not a documented path. [8]
Batteries — no user-replaceable cell and no battery-replacement path. Capacity in mAh is not published, so an ageing battery is not something an owner can swap out. [1][8]
USB-C charging cable — a 20-inch USB-A to USB-C cable is included, so there is nothing extra to buy for charging. [5]

Yearly running cost

Not enough data for a dollar figure. The computable part is zero: there are no filters, pods or subscriptions for this product, Edifier sells no ear tips, earbud assemblies or batteries for it, and charging runs over the USB-C cable in the box from a phone adapter the owner already owns. The one cost that eventually appears is battery degradation — new earbuds measured 4 h 40 min and 4 h 51 min with ANC on — and nothing in the research says how much of that is left after a year or two, so any loss becomes a whole-pair replacement rather than a service. [1][2]

When it is a good buy

At or below the $49.99 MSRP SoundGuys recorded for the 2023 launch, this is strong value: measured ANC, a real app with EQ presets and touch remapping, wear detection, game mode and IP54 are unusual at that level. It stays defensible from $50 to $60 for gym and commuter use, where four and a half hours of ANC is enough, and it beat the Soundcore Life A3i on mid-frequency cancellation in one head-to-head. From $60 to $80 the value erodes, and above $80 it is weak. Three named alternatives: the EarFun Air S, about $10 more, adds 5 h per charge, multipoint and 50 ft of range; the Edifier W240TN, a different body, runs more than 6 h per charge; the EarFun Air Pro 3, about $30 more, adds 8+ h per charge, IPX5, multipoint and the LC3 codec. No current US street price was verified in the research, and every defensible price reference is a 2023-2024 review-era figure. [1][2][3][12][13]
