If you want marathon battery life with an IPX8 waterproof build and deep in-app sound tweaking, choose TOZO Hybrid Active Noise; if you need Hi-Res codec support like aptX Lossless (plus LDAC, LC3 and LE Audio) with dual-driver tuning and real-time AI translation, choose EarFun Air Pro 4+.
• TOZO Hybrid Active Noise — biggest strength: 68 hours of total playtime with the case, IPX8 waterproofing, and a 32-preset EQ app make it a do-everything daily driver.
• TOZO Hybrid Active Noise — biggest trade-off: Its codec list tops out at Bluetooth 5.3 wireless audio, so it doesn't offer the aptX HD / aptX Lossless style hi-res codec support the EarFun model advertises.
• EarFun Air Pro 4+ — biggest strength: Qualcomm QCC3091 with Snapdragon Sound, aptX Lossless, LDAC, LC3 and LE Audio, plus a hybrid dual-driver setup and ANC rated up to 50dB.
• EarFun Air Pro 4+ — biggest trade-off: Its published specs don't include a playtime figure or a waterproof rating, so buyers who care about all-day battery or sweat-heavy workouts get less to go on.
• Who each pick is for: TOZO for commuters, runners and long-shift listeners who want battery and waterproofing; EarFun for Android power users chasing the best codec and a more audiophile-leaning tuning.
The TOZO NC3 is built around endurance. TOZO rates it at up to 13 hours per charge with ANC off and 68 hours total with the case; flip ANC on and you're looking at up to 9.5 hours per charge and 40 hours total. A 10-minute top-up returns up to an hour of playback, which is the kind of detail that matters when you're walking out the door and realize the case is nearly flat. SmartPow power management is the behind-the-scenes piece that keeps those numbers honest in daily use.
Noise cancelling is hybrid and rated up to -45dB, aimed squarely at steady low-frequency noise — subway rumble, plane engines, air-conditioning hum — with multiple ear tip sizes to help you get a proper seal. TOZO ships six pairs of ear caps (XS through XXL), which is genuinely more sizing flexibility than most in-ear buds offer, and it matters because ANC performance collapses without a good seal. There's also a Transparency Mode for announcements and quick conversations without pulling the buds out.
Sound comes from a 12mm dynamic driver with TOZO's OrigX 2.0 tuning and Bass Plus, covering a 20Hz–20KHz range. The companion app offers 32 EQ presets, EQ sharing, white noise tracks, and AI chat and translation features. Bluetooth 5.3 handles the wireless side with auto-pairing on case open and a one-key reset on the case.
Buy it if you want a single pair for long commutes, gym sessions and rainy runs — IPX8 waterproofing plus 68 hours of case battery is a hard combination to beat for that lifestyle.
Skip it if hi-res codec support is your priority. There's no aptX HD or LDAC listed here, so if you're chasing lossless-grade streaming quality, look at the EarFun instead.
The EarFun Air Pro 4+ is the codec-forward pick. It runs on the Qualcomm QCC3091 SoC and is certified for Snapdragon Sound with aptX Lossless, with additional support for LDAC, LC3 and LE Audio. If you've been searching for which earbuds support aptX HD-style hi-res transmission, this is the model in this comparison that's actually built around that answer. Pair it with a compatible Android phone and you're working with a far richer codec toolkit than Bluetooth 5.3 baseline audio.
The driver design is a hybrid system: a 10mm composite dynamic driver paired with EarFun's FeatherBA balanced armature, set at an 11-degree angle alignment that the brand says minimizes high-frequency attenuation. The frequency range is listed at 20Hz–40kHz — a wider top end than the TOZO's 20KHz ceiling, which is consistent with a Hi-Res Audio claim. Practically, that means more air and detail up top, with the dynamic driver handling the low end.
ANC is adaptive hybrid, rated up to 50dB, and it automatically adjusts cancellation levels based on your surroundings rather than sitting at one fixed setting. Six AI-enhanced ENC microphones handle calls. There's also real-time AI translation across 100+ languages through the EarFun Audio App, in both Real-Time and Face-to-Face modes — a genuinely unusual feature you won't find on the TOZO.
Buy it if you're on a Snapdragon Sound device or a phone that supports LDAC, you want a balanced-armature hybrid for detail retrieval, or translation features appeal to you.
Skip it if you need a published battery figure or a waterproof rating to feel confident. Neither appears in the specs, and that's a real gap for gym and outdoor buyers.
Side-by-Side: Which Should You Choose?
• Best for battery life → TOZO Hybrid Active Noise. 68 hours total with the case, 40 hours with ANC on, and a 10-minute quick charge for an hour of playback.
• Best for workouts and rain → TOZO Hybrid Active Noise. IPX8 waterproofing is explicit; the EarFun sheet lists no water-resistance rating at all.
• Best for noise cancellation ceiling → EarFun Air Pro 4+. Rated up to 50dB adaptive hybrid versus TOZO's up to -45dB hybrid.
• Best for sound customization → TOZO Hybrid Active Noise. 32 EQ presets, EQ sharing in the EQ Zone, plus white noise tracks in the app.
• Best for driver architecture nerds → EarFun Air Pro 4+. A 10mm dynamic plus balanced armature hybrid, with a 20Hz–40kHz range.
• Best for travel and language barriers → EarFun Air Pro 4+. Real-time translation across 100+ languages in two modes.
• Best for call clarity in noisy places → toss-up. Both list 6 microphones with ENC; TOZO leans on 6-mic ENC, EarFun on 6 AI-enhanced ENC mics.
In my opinion, the EarFun Air Pro 4+ is the more interesting buy for anyone whose priority is audio quality and codec flexibility — aptX Lossless, LDAC and a hybrid dual-driver with a 40kHz ceiling is a genuinely different class of hardware, and the 50dB adaptive ANC plus real-time translation seal it. But I'd point most everyday buyers to the TOZO Hybrid Active Noise, because 68 hours of playtime, IPX8 waterproofing and six ear tip sizes solve the problems people actually hit day to day. If you own a Snapdragon Sound or LDAC phone, go EarFun. If you just want buds that survive the gym, the rain and a long week, go TOZO. Check the current price on Amazon before deciding — that's the one variable this comparison can't settle for you.
FAQ
which earbuds support aptx hd
Of these two, the EarFun Air Pro 4+ is the one built for hi-res codecs: it uses the Qualcomm QCC3091 SoC and supports aptX Lossless plus LDAC, LC3 and LE Audio. The TOZO Hybrid Active Noise lists Bluetooth 5.3 but no aptX HD or LDAC support, so it stays on baseline wireless audio.
Yes — it carries an IPX8 waterproof rating, which covers sweat, rain and splashes, and it ships with six pairs of ear tips (XS–XXL) for a secure fit. The EarFun Air Pro 4+ spec sheet doesn't list a water-resistance rating, so I'd be more cautious taking those out in heavy rain.
TOZO rates it at up to 13 hours per charge and 68 hours total with the case with ANC off. With ANC on, that drops to up to 9.5 hours per charge and 40 hours total. A 10-minute quick charge gives up to an hour of playback.
Yes. It supports real-time AI translation across 100+ languages through the EarFun Audio App, with both Real-Time and Face-to-Face modes. EarFun notes the app needs to be updated to the latest version for it to work properly.
