Sony WF-C710N (Black): problems, parts and running costs

Checked: 2026-10-19

Summary

Sony’s stemless entry-level noise-cancelling earbud with a 5 mm driver, Bluetooth 5.3, SBC/AAC-only codecs, multipoint for two devices and a claimed 8.5 h per charge, 30 h total with NC on. Professional reviews praise the ANC per dollar and the battery, but fit is the gamble: there are no fins or hooks and multiple owners report the buds falling out. There are no consumables with prices; running cost is electricity and replacement ear tips, and it is a strong buy at the $83.97 Newegg street price (April 2025) but weak at Sony’s $129.99 direct price.

Common problems and fixes

Buds falling out — the most divisive issue across sources: no stabilizing fins or hooks and only three ear-tip sizes, and owners report the buds falling out during walking, workouts or sleep; try before buying, since fit is ear-shape dependent. [6][8][14]
Case stops charging the buds — owners report the case no longer charging the earbuds after some use, and “battery drains in charging case” is a top con in RedditRecs’ aggregate; no fix is documented. [17][18]
No LDAC or aptX — SBC and AAC only, unusual for a Sony product and a real limitation for Android users; the only fix is a different headset. [6][7][8]
No wireless charging — charging is USB-C only, about 1.5 h for the buds and 3.5 h for the case, despite the case being a recurring complaint topic. [6][8]
Ambient Sound mode hiss — the mode introduces noticeable hiss and weak high-frequency reproduction; owners use it sparingly or keep ANC on. [6]
Ear-tip wear — the tips wear down over time and replacements that fit both earbuds and case are hard to find, per an owner after 1-2 years of use. [8]
Latency too high for gaming — RTINGS states latency is too high for gaming; not a fixable issue. [5]

Parts and consumables

No other replaceable parts or consumables are reported; the battery is not user-replaceable and Sony publishes no repair-parts catalog for this model. [2]

Yearly running cost

No subscription or accessory lock-in is reported. Not enough data to compute a yearly figure.

When it is a good buy

$83.97 at Newegg (April 2025, Tom’s Guide and T3) — a strong buy at or under about $85, where the codec and fit limitations matter less. [7][10]
$69.99 at Best Buy (Reddit owner, 2025-2026) — the strongest price seen. [14]
$128 at Sweetwater, Walmart and Best Buy (April 2025) — fair value in the $111-130 band. [7][10]
$129.99 at Sony USA direct (October 2026) — weak unless you want the Sony ecosystem, wear detection or the design; PCMag’s Editors’ Choice Anker Soundcore Liberty 4 Pro at $129.99 adds LDAC, IP54 and a more secure fit and is the better choice there. [1][6]
