— THE VERDICT · JUDGEANY EDITORSWhat the Air Pro 4 is
The Air Pro 4 (model TW600) is EarFun's 2024 flagship earbud, priced at $89.99, and the spec sheet aims high: 10mm composite-diaphragm drivers, Bluetooth 5.4 on Qualcomm's QCC3091 with Snapdragon Sound certification, and a codec list covering aptX Lossless, aptX Adaptive, LDAC, and LE Audio. Adaptive hybrid ANC (QuietSmart 3.0) is rated up to 50dB with five modes, including wind-noise and AI-adaptive profiles. Battery comes in at 11 hours per bud with ANC off (7.5 with it on), 52 hours total with the case, plus wireless charging and a 10-minute top-up worth about 2 hours. Six mics with Qualcomm cVc 8.0 handle calls, the buds carry an IPX5 water rating, and the EarFun app packs a 10-band custom EQ, multipoint management, a sub-50ms game mode, in-ear detection, and Find My Headphones. Colors are black and glossy white.
Sound and codecs
SoundGuys gives the Air Pro 4 8.4 out of 10 with its Recommended badge, naming it their top pick among wireless earbuds under $100. The sound is likable out of the box, LDAC and aptX Lossless work on supported Android phones, and the 10-band EQ in the app covers most complaints. One caveat from their lab: switching ANC on subtly shifts the sound signature, and isolation scored only 5.7 -- the ANC does the heavy lifting. Tom's Guide lands in the same place, calling these 'budget buds for audiophiles' with sound that holds up across genres; the bass-heavy default that some reviewers flagged trims down fine in the EQ. TechGearLab is cooler on the sound itself (6.7) but still rates the overall package 66 out of 100. We run no lab; the scores below are editorial judgments on this published evidence.
ANC and battery
EarFun's 50dB figure is EarFun's own number, but reviewers broadly back the effect. Tom's Guide calls the adaptive ANC effective across its five modes, and GamesRadar says EarFun used ANC to the best of its ability. Battery life holds up to the claims: the rated 11 hours (ANC off) / 7.5 hours (ANC on) per charge checked out in testing -- Tom's Guide got 8 real hours per charge with ANC on, TechGearLab measured 7.8, and GamesRadar found the 52-hour total accurate after a month of use. Wireless charging is included, a 10-minute top-up returns about 2 hours, and a full case charge takes roughly 90 minutes per Tom's Guide. The modest knocks: ANC modes can take a moment to settle, and sound bleeds out at high volumes -- Tom's Guide warns coworkers will hear your playlist.
Calls, comfort, and the app
The six-mic array with Qualcomm cVc 8.0 is the weak link. SoundGuys calls the mics mediocre in noisy environments, and TechGearLab's 5/10 call-quality score agrees. In quiet rooms, reviewers found calls perfectly usable. Comfort gets no complaints: the buds are light (about 0.17 oz each per Tom's Guide), and Tom's Guide wore them for 8 straight hours without discomfort; SoundGuys scores comfort 8.5. The EarFun app is above average for the price -- 10-band EQ, ANC mode selection, touch control customization, firmware updates, and multipoint -- though Amazon owners report the app can be slow and unresponsive on iPhones, and the in-ear detection sometimes pauses music on its own. Multipoint connects two devices, Google Fast Pair and LE Audio/Auracast support are included, and game mode promises under 50ms latency.
Who should buy it
Buy the Air Pro 4 if you want flagship codec support and strong ANC for under $100 -- it is SoundGuys' top budget pick, and Tom's Guide's long-term reviewer ditched AirPods Pro 2 for them. It suits Android users who can actually use aptX Lossless or LDAC, commuters who want adaptive ANC, and anyone who charges on a wireless pad. Skip it if you take most calls on windy streets, if you listen at max volume in a shared office (they leak), or if you are on iPhone and the hi-res codec list was the draw -- iOS gets neither LDAC nor aptX. Don't confuse it with the newer Air Pro 4+ (Bluetooth 6.0, 54h, dual drivers, 2025) or the 4i; this review covers the 2024 Air Pro 4. Check the live Amazon price -- EarFun discounts these hard, with several sub-$55 sales in 2026, including an Amazon Lightning deal at $53.16 reported by SoundGuys in July 2026.
