• EarFun Air Pro 4 — biggest strength: Adaptive hybrid ANC rated up to 50dB, Snapdragon Sound with aptX Lossless and LDAC, plus up to 52 hours total playtime with the case — a true all-rounder for calls, commuting and streaming.
• EarFun Air Pro 4 — biggest trade-off: It only works wirelessly over Bluetooth, and its battery is small per charge (about 11 hours), so you're always dependent on the charging case and a charged phone.
• SHANLING M0s — biggest strength: A self-contained hi-res player with 384kHz/32bit and DSD128 support, 60mW @32Ω output, and a USB-C DAC/amp mode that upgrades a computer's audio.
• SHANLING M0s — biggest trade-off: It's a wired-first device with a 10-hour battery and a 1.54-inch screen — no active noise canceling and no earbuds included, so it's not a grab-and-go wireless solution.
• Who each is for: Pick the EarFun Air Pro 4 if you want one gadget for music, calls and quiet; pick the SHANLING M0s if you already own good wired headphones or IEMs and want a better source for them.
The EarFun Air Pro 4 is built around the idea that one pair of earbuds should handle everything. Its headline feature is adaptive hybrid active noise canceling rated up to 50dB, powered by QuietSmart 3.0 — the earbuds adjust the cancellation to your ear canal rather than applying one fixed profile. For a commuter on a noisy train or a frequent flyer, that's the feature that matters most, because it's the difference between hearing your music and hearing the engine.
On the audio side, EarFun leans hard into codec support. There's a Qualcomm QCC3091 SoC with aptX Lossless and certified Snapdragon Sound, plus LDAC, LE Audio and LC3 support, driving a 10mm dynamic driver with 32 ohm impedance and a 20Hz–20kHz response. In practice that means the earbuds can take advantage of a high-fidelity source if you have one, and the companion app's Sound Profile EQ lets you shape the tuning to taste. Calls get six microphones with AI processing and Qualcomm cVc 8.0, which is a lot of hardware aimed at one job: making your voice clear when there's background noise.
Battery and connectivity round it out. You get roughly 11 hours per charge and up to 52 hours with the USB-C case, plus a 10-minute quick charge that adds about 2 hours. Bluetooth 5.4 with multipoint means two devices at once, and Google Fast Pair smooths Android setup. Touch controls and app control handle everything, and there's no headphone jack — this is a wireless-only product.
Who should buy it: anyone who wants a single pair of earbuds for music, calls and noise canceling, especially Android users with a Snapdragon Sound phone. Who should skip it: listeners who want a wired, battery-independent setup, or who prefer over-ear or dedicated players for critical listening.
The SHANLING M0s solves a completely different problem: it's a standalone digital audio player for people who care about the source, not the wireless convenience. It plays 384kHz/32bit files and DSD128, and its DAC and 60mW @32Ω output are aimed squarely at driving serious wired headphones and IEMs. If you've been plugging good earphones into a phone and feeling like something is missing, that output power and file support are the reason the M0s exists.
Its second life is as a USB-C DAC/amp. Plug it into a PC, Mac or smartphone and it becomes an external sound card and headphone amplifier — a genuinely useful trick for a laptop with weak onboard audio. Around that, SHANLING adds dual-way Bluetooth 5.0 with LDAC and aptX, so the M0s can act as a Bluetooth receiver streaming from your phone, or send audio out to wireless headphones. That's unusual flexibility for a player this small.
The physical design is deliberately minimal: a 1.54-inch HD LCD touch screen, a pocket-sized black body, and support for FLAC and DSD among other formats. Battery life is about 10 hours — perfectly fine for a commute or a session, but not a multi-day device. Controls include a volume wheel and touch navigation. There are also smart audio features like AB repeat and variable playback speed from 0.5x to 2.0x, which make it surprisingly good for language learning, podcasts and instrument practice.
Who should buy it: anyone with wired headphones or IEMs who wants better sound on the move and a desktop DAC/amp in the same box, plus students and language learners who'll use the speed and repeat tools. Who should skip it: people who want noise canceling, true wireless freedom, or a single device for calls — the M0s has none of those.
• Best for noise canceling → EarFun Air Pro 4. Adaptive hybrid ANC up to 50dB is a feature the M0s simply doesn't have.
• Best for sound quality with wired headphones → SHANLING M0s. 384kHz/32bit, DSD128 and 60mW @32Ω output are built for critical listening.
• Best for total battery life → EarFun Air Pro 4. Up to 52 hours with the case versus about 10 hours on the M0s.
• Best for desk and laptop audio → SHANLING M0s. Its USB-C DAC/amp mode turns it into an external sound card for PC, Mac or phone.
• Best for calls and meetings → EarFun Air Pro 4. Six mics with AI processing and cVc 8.0 are designed for voice clarity.
• Best for a no-phone listening session → SHANLING M0s. It stores and plays your own files without needing a handset at all.
• Best for wireless convenience → EarFun Air Pro 4. Bluetooth 5.4, multipoint and Google Fast Pair beat the M0s's Bluetooth 5.0 for everyday pairing.
• Best for language learning and practice → SHANLING M0s. AB repeat and 0.5x–2.0x playback speed are purpose-built for it.
If I could only buy one, I'd take the EarFun Air Pro 4. In my opinion it covers far more of daily life — noise canceling for the commute, six mics for calls, multipoint for laptop-and-phone switching, and a case that keeps it running for days. The SHANLING M0s is the better specialist and I'd happily recommend it to anyone who already owns good wired IEMs or wants a proper desktop DAC/amp. But as a single purchase, the EarFun Air Pro 4 is the one I'd reach for every morning.
They do different jobs. The EarFun is true wireless earbuds with noise canceling and long battery life; the M0s is a wired-first hi-res player and USB DAC/amp. "Better" depends entirely on whether you want wireless convenience or a dedicated source.
No. The EarFun Air Pro 4 is wireless-only over Bluetooth 5.4 — there's no jack, so wired listening isn't an option. If you need a 3.5mm output, the SHANLING M0s has one, along with USB-C.
The EarFun Air Pro 4. It's rated around 11 hours per charge and up to 52 hours with the charging case, with a 10-minute quick charge adding roughly 2 hours. The SHANLING M0s is rated about 10 hours, and it doesn't come with a charging case.
For stored files, largely yes — it plays FLAC and DSD, supports 384kHz/32bit and DSD128, and works without a phone. But it has no cellular or streaming app ecosystem, so it's a companion device, not a phone replacement.
For a commute I'd lean toward the EarFun Air Pro 4, purely because adaptive ANC up to 50dB and a pocketable charging case suit noisy travel better. If your commute is quiet and you use wired IEMs, the M0s is the more rewarding listen.
