• Sony WF-C510 — biggest strength: a genuinely pocketable in-ear design with up to 11 hours per charge (22 hours with the case), IPX4 splash resistance and Bluetooth 5.3 multipoint for switching between two devices.
• Sony WF-C510 — biggest trade-off: these are in-ear buds with no noise cancelling and no boom mic, so call clarity in a noisy office is not their strong suit.
• EMEET Airflow Open Ear — biggest strength: a work-first headset with a detachable boom mic, dual-channel noise cancellation rated to cut up to 50dB, one-touch mute and a USB dongle for low-latency 40ms switching.
• EMEET Airflow Open Ear — biggest trade-off: it is a larger open-ear headset with a charging station and accessories, so it is not the discreet little pair you toss in a jeans pocket.
• Sony WF-C510 is for: commuters, gym-goers and everyday listeners who want music and calls from a phone in a small package.
• EMEET Airflow Open Ear is for: people who live on video calls and want an open ear so they can still hear the room.
The WF-C510 is a classic true wireless earbud built around two ideas: comfort and battery. Sony describes it as light and compact with a fit designed to sit in your ear all day, and the case is small and cylindrical so it slides into a pocket or a bag without fighting for space. The white finish is clean and simple, and the earbuds are available across a few colours if you want something less plain.
On the numbers, you get up to 11 hours of playback per charge and up to 22 hours total with the case, plus a quick charge that gives roughly an hour of playback from five minutes on the charger. Bluetooth 5.3 handles the connection, and multipoint lets the earbuds stay paired to two devices at once, so when a call comes in the buds connect to whichever device is ringing. There is an IPX4 rating, which means splashes and sweat are not a problem, and a built-in microphone with wind noise reduction for hands-free calls.
EMEET Airflow Open Ear: Who It's For
The EMEET Airflow is not really a music-first earbud — it is a work headset that happens to play music too. It uses air conduction with an open-ear fit and ultra-soft silicone pads, so nothing plugs your ear canal. That design choice is the whole point: you keep your ear open to the room while still hearing the call. If you work from home, take meetings back to back, or need to hear a colleague walk up behind you, that matters more than isolation.
The calling hardware is the headline. A detachable boom microphone sits close to your mouth, and EMEET pairs it with dual-channel noise cancellation that the spec sheet rates at removing up to 50dB of live and remote noise, plus one-touch mute for privacy. It is Zoom certified and carries dedicated headset controls, which tells you who it was built for: people whose job is meetings. There is also sound leakage prevention, so the person next to you is less likely to hear your call.
For audio, a 16.2mm dynamic driver pushes bass and volume, and spatial audio adds a surround-style effect with head-movement tracking. Connectivity is Bluetooth 5.3 with a USB dongle, and the multipoint support lets you hop between two devices — laptop and phone, for example — with 40ms latency that keeps audio and video lined up. Battery is up to 20 hours of talk time and up to 40 hours of playback, with a five-minute charge giving about an hour. IPX5 means it handles sweat and splashes better than the Sony's IPX4. The trade-offs are bulk and cost of complexity: a charging station, a dongle and a detachable mic boom are all things to keep track of, and open-ear means no isolation at all.
Side-by-Side: Which Should You Choose?
• Best for battery life → EMEET Airflow Open Ear. Up to 40 hours of playback and 20 hours of talk time beats the Sony's 22 hours with the case.
• Best for portability → Sony WF-C510. A small cylindrical case and 31g total weight versus a headset plus charging station and dongle.
• Best for blocking out the world → neither, honestly. The Sony has no noise cancelling and the EMEET is deliberately open-ear. If isolation is your priority, look elsewhere.
• Best for hearing your surroundings → EMEET Airflow Open Ear, by design; the Sony's Ambient Sound Mode gets you partway there, but only when you switch it on.
• Best for the gym and sweaty commutes → Sony WF-C510. IPX4 and a secure in-ear fit are fine for splashes and sweat, and there is nothing extra to lose.
• Best for video meetings and laptop work → EMEET Airflow Open Ear. The USB dongle and 40ms latency exist precisely for that.
• Best for app-tuned casual listening → Sony WF-C510. EQ via the Sony Headphones Connect app plus DSEE for compressed files is a listener-first feature set.
In my opinion, the right pick comes down to what your day actually looks like. If you spend most of your listening time on a phone — music on the train, a podcast while walking, the odd call — I would buy the Sony WF-C510, because the compact fit, 22-hour total battery and multipoint switching cover that life with nothing extra to carry. If your day is meetings, I would buy the EMEET Airflow Open Ear, because the detachable boom mic, one-touch mute, Zoom certification and USB dongle are built for exactly that job, and the open ear keeps you present in the room. Multipoint is on both, so that is not the deciding factor — your use case is.
what is multipoint bluetooth headphones
Multipoint is a Bluetooth feature that keeps a headset paired to two devices at once — a laptop and a phone, say — and switches audio to whichever one is active. Both the Sony WF-C510 and the EMEET Airflow Open Ear support it, so a call on your phone can take over from music on your laptop without re-pairing.
can bluetooth headphones connect to multiple devices
Yes, if they support multipoint. Both headphones here run Bluetooth 5.3 and list multipoint, meaning two devices stay connected simultaneously and the headset routes sound to the device that needs it. Without multipoint, most Bluetooth headphones only remember one active connection at a time.
which headphones have bluetooth multipoint
Of these two, both do: the Sony WF-C510 explicitly lists multipoint for switching between two devices, and the EMEET Airflow Open Ear lists multi-point alongside its USB dongle. If multipoint is a must-have, either works — pick based on whether you want in-ear buds or an open-ear work headset.
is the EMEET Airflow better for calls than the Sony WF-C510
For calls, yes — in my opinion. The EMEET has a detachable boom mic, dual-channel noise cancellation rated up to 50dB, one-touch mute and Zoom certification, while the Sony relies on a built-in bud microphone with wind noise reduction. For casual phone calls the Sony is fine; for all-day meetings the EMEET is the more purpose-built tool.
