EarFun Free 2S: problems, parts and running costs
Checked: 2026-10-17
Summary
The Free 2S is a budget true wireless earbud whose real compromises are sound tuning (a fatiguing high-frequency spike), a smooth chassis that can slip in small ears, and microphones that buffet in wind; it has no active noise cancellation or hear-through mode. There are no subscriptions, so yearly cost is limited to third-party ear tips and the electricity for charging, neither of which the sources price. EarFun lists it at $59.99, and the sources’ value analysis is strongest at $30 or under.
Common problems and fixes
- Fit can be insecure for small ears — Wirecutter found the smooth chassis has less grip and people with very small ears may have trouble keeping the buds in place, while one owner said the fit beats AirPods Pro for larger ears. [2][1]
- Wind noise on calls — the microphones are not wind-resistant and a solid gust causes buffeting sound; no fix is reported. [2]
- Touch controls are fussy — Wirecutter found them fussier than physical buttons. [2]
- Warranty service friction — the 18-month warranty is longer than typical for budget earbuds, but Reddit users report returns directed to China and small refund offers instead of replacements. [1][5]
- Charging contacts and dust filter need periodic cleaning — EarFun’s FAQ recommends cleaning the charging contacts with alcohol if the buds fail to charge, cleaning the dust filter every 3–5 days to prevent volume imbalance between the earbuds, and drying the buds before placing them in the case. [6]
- No active noise cancellation or hear-through mode — Wirecutter lists this as the missing feature compared with newer budget models. [2]
Parts and consumables
Yearly running cost
No subscriptions, and the EarFun Audio app is free [1]. One owner reported five years of daily 12–20 hour shift use before the earbuds failed — the only longevity data point in the sources [4]. Electricity for charging is not priced in the sources, so a yearly dollar figure cannot be computed.
When it is a good buy
The sources’ value analysis: strong value at $30 or under, good from $31 to $50, fair from $51 to $60, weak above $60. EarFun lists the Free 2S at $59.99 (official page, October 2026), and Wirecutter named it their budget pick for wireless earbuds in 2026 [2]. If you want active noise cancellation, the newer EarFun Air Pro 4 is the in-brand alternative the sources point to — it is the better choice when ANC matters more than IPX7 waterproofing and wireless charging [2].
