EarFun Air 2: problems, parts and running costs
Checked: 2026-10-17
Summary
The most consistent complaints are touch controls that drop multi-tap gestures, no active noise cancellation with mediocre passive isolation, and LDAC cutting battery life and range when it is enabled. The charging case hinge is thin and the case itself is not waterproof, so it is the part that most needs care. There is nothing to buy on a schedule and no subscription, so the yearly running cost is charging electricity alone. It is a strong buy at $50 or less, reasonable from $50 to $65, and weak above $65. [1][3][4]
Common problems and fixes
- No noise cancelling and mediocre passive isolation — there is no ANC at all, and Headphones Addict measured average passive isolation of 11.01 dBA, fine in a quiet room and poor on a train or plane. No fix; if commuting is the priority, choose a model with ANC. [2][4]
- LDAC cuts battery life and range — per-charge life drops from 9 h to 5.5 h with LDAC on, one test saw Bluetooth range fall from 35 ft to 30 ft, and enabling LDAC disables multipoint. LDAC also needs a firmware update out of the box and works only on Android 8.0 or newer, so keep it off unless the source is hi-res Android. [1][3][4]
- Thin case hinge and a case that is not waterproof — Headphones Addict flags the hinge as a potential failure point, and despite the IPX7 earbuds the manufacturer says to keep the case away from sweat. Handle the lid gently; no repair parts exist. [1][4]
- Comfort and fit issues — What Hi-Fi? reported aching on long journeys and Headphones Addict found the buds can work loose during intense movement or running. Try all four included silicone sizes for a better seal. [2][4]
- One bud goes quiet or silent — the manufacturer FAQ advises cleaning the speaker mesh with a toothpick or a cotton swab dipped in alcohol, then a reset and re-pair cycle. [1]
Parts and consumables
- USB-C charging cable — a USB-A to USB-C cable is included; a spare is the only extra most owners buy, since the case also charges wirelessly. [1][4]
- Batteries — no capacity figures were published and no battery-replacement programme was found, so an aged battery ends as a replacement event rather than a repair. [1]
Yearly running cost
Not enough data to total. There is no subscription and no proprietary consumable, so normal listening costs nothing per year; the only scheduled spend would be aftermarket ear tips and eventually a replacement set once the cells age, and no prices for either were verified. Charging is negligible — 1.5 h for the earbuds, 2 h for the case over USB-C and 3.5 h wirelessly — and no owner-reported electricity figure exists. [1][4]
When it is a good buy
EarFun sells the Air 2 at $49.99, marked down from $69.99 (EarFun, 2026), and CNN Underscored documented a $35 deal with a promo code in early 2024 [1][3]. At $50 or less the LDAC, IPX7, wireless charging and 40-hour battery package is strong value. From $50 to $65 it stays reasonable, but competing products with ANC enter the band. Above $65 it is weak value for 2026. One named alternative: the EarFun Air 2 NC adds active noise cancellation at about $70 but drops to IPX5, so it is the better choice when noise cancelling matters more than water resistance [7]. iOS users get less out of LDAC and should compare more balanced packages.
