Problems, parts and running costs

Summary

A budget true-wireless ANC earbud with a long feature list, high-end codec support and above-average measured battery life, aimed at buyers who want a lot for a small outlay. Check your phone’s codec support and be ready for a busy app plus recurring owner reports of faint hiss and connection trouble.

Strengths

  • Strong measured battery life, with 8 hours 44 minutes from the buds in SoundGuys’ test.
  • Adaptive ANC is effective for a budget pair once the seal is good; SoundGuys measured 10–20 dB of extra attenuation over passive isolation.
  • Codec breadth, multipoint, wear detection and wireless charging cover far more than the price suggests.
  • Sound quality is a repeated strength across professional reviews.
  • The case is compact and adds real total runtime.

Weaknesses

  • Several owners describe a faint hiss or electronic crackle, most noticeable in quiet rooms with ANC on.
  • Connection and pairing can be unstable, especially with LDAC, aptX, game mode or multipoint all active.
  • Reports of a bud failing to charge or reading 0% recur, though no failure rate is published.
  • The app and its many ANC and EQ choices are more complicated than they need to be.
  • Stock tips do not seal well for every ear, which weakens bass and ANC until you fit a better tip.
  • Microphone quality in noise is only average, and the earbuds and case are not user-repairable.

Sound, ANC and codecs

SoundGuys measured 8 h 44 min from the buds, and Tom’s Guide got about 8 h before returning them to the case. TechRadar called the stock tuning bass-forward with recessed mids and treble until you EQ it, and heard occasional peaking; SoundGuys found the default tuning close to its preference target. ANC is generally considered effective for the money when the fit is good, and SoundGuys measured 10–20 dB of extra attenuation over passive isolation, with Strong ANC cutting perceived external-noise loudness by about 75%. The claimed 50 dB maximum is a manufacturer figure with no independent attenuation benchmark behind it. LDAC needs a compatible Android source, iPhones do not support LDAC or aptX Lossless, and high-bandwidth codecs, game mode and multipoint can trade against stability.

Fit and comfort

Fit changes bass and ANC more than any setting. The box includes five tip sizes, but some owners say the stock tips do not hold a seal during movement and switch to third-party tips. If the bass sounds thin, try a larger tip before blaming the driver.

Reliability, support and upkeep

EarFun backs the Air Pro 4 with an 18-month warranty for quality-related defects on direct purchases and a 30-day money-back policy for its sales channel. Independent owner threads describe faint ANC hiss and electronic crackle, pairing and reconnection trouble, and occasional charging or dead-bud failures. A one-year owner had the right bud stop charging after about six months and later saw flickering charging LEDs on the replacement case; EarFun replaced both quickly, and another owner reported a replacement in two days. A different owner reported a failed pair after about a year and eventually got a refund, and a 2026 prospective buyer said two pre-sale emails went unanswered, so responsiveness is not uniform. None of the reports establishes a defect rate.

EarFun’s own troubleshooting suggests disabling LDAC, game mode, aptX or multipoint when connections become unstable, and says slight ANC background noise can be normal in very quiet rooms. Keep the charging contacts and speaker mesh clean, and confirm each bud is actually charging. The earbuds and case are sealed, with no user-serviceable battery or charging parts, so hardware failures go through warranty rather than repair. An optional case cover was $9.99 from EarFun.

Running costs and what you get

Routine annual cost is effectively nothing. There is no subscription, no required consumable and no proprietary service fee, and charging at the official DC 5 V / 1 A input is negligible next to the purchase price. The real long-term cost is replacing the earbuds once the sealed batteries age or a hardware failure appears. Sale pricing has been aggressive: EarFun normally sells it direct at $89.99, while its October 2026 8th Anniversary page listed the original Air Pro 4 at $50.51 and the newer Air Pro 4+ at $69.99 at the same event.

Is it worth it?

Below $55 this is an excellent buy: measured battery life, effective ANC, codec breadth, multipoint and wireless charging are exceptional at that price, with the reliability caveats already priced in. From about $56 to $65 it remains very good value. From about $66 to $75, compare the Air Pro 4+ first, since it was $69.99 during the same anniversary event and adds dual drivers, IP55, Bluetooth 6.0 and a longer battery figure. Above $79 the original Air Pro 4 gets hard to justify in October 2026, because Nothing’s Ear (a) was $59 in its Fall Sale with LDAC, 45 dB ANC, multipoint and up to 42.5 h total playback, and Soundcore’s Liberty 4 NC lists at $99.99 with promo prices around $69.99. At the full $89.99 direct price, wait for a sale or buy the newer model unless a specific fit or codec preference makes this one preferable.

Which model this is

This page covers the original 2024 EarFun Air Pro 4 in black, ASIN B0D5M9SH1X. It is not the Air Pro 4+ and not the Air Pro 4i. SoundGuys lists the model number TW600 and EarFun’s product-guide catalog uses TW600B, so treat TW600 as secondary identification until an official label confirms it. Check the codec list for your phone before buying, since LDAC and aptX Lossless depend on the source device.
