• Sony WH-CH520 — biggest strength: Up to 50 hours of playback with a 3-minute quick charge that yields 1.5 hours of listening, plus 360 Reality Audio and DSEE sound enhancement.
• Sony WH-CH520 — biggest trade-off: On-ear pads and no active noise cancellation, so it blocks noise passively at best.
• EMEET Airflow Open Ear — biggest strength: Detachable boom mic plus dual-channel noise cancellation rated to cut up to 50dB, with Bluetooth 5.3 multipoint and a USB dongle for switching between two devices.
• EMEET Airflow Open Ear — biggest trade-off: Shorter battery life (up to 20 hours talk, 40 hours playback) and an open-ear design that trades isolation for spatial audio and IPX5 water resistance.
• Pick Sony WH-CH520 for all-day music and casual calls; pick EMEET Airflow Open Ear for meetings, calls and multi-device workflows.
The WH-CH520 is the straightforward choice for someone who wants a wireless on-ear headphone that just keeps going. Sony rates the battery at up to 50 hours, and a 3-minute quick charge buys you 1.5 hours when you're caught short. That combination is genuinely useful if you're the type who forgets to charge overnight and doesn't want a dead headphone on the commute.
The feature set is built around listening, not meetings. The Digital Sound Enhancement Engine (DSEE) restores high-frequency detail lost in compressed audio, and you can shape the sound with EQ presets in the Sony | Headphones Connect app. It's also 360 Reality Audio certified, and the app analyses your ear shape to optimise the spatial effect. Bluetooth 5.2, Swift Pair and Fast Pair keep pairing painless, and there's a multipoint connection so it can hold two devices at once.
On calls, the built-in mic uses noise suppression to reduce ambient sound, and one click on the earcup buttons answers a call without pulling out your phone. But be clear about what this is not: there's no active noise cancellation here, so it's best in quiet-to-moderate environments. It's also on-ear, not over-ear, and there's no headphone jack — wireless only. If you want ANC or wired fallback, skip it.
The EMEET Airflow is a work headset first and a music device second, and it's honest about that. The headline is the detachable boom microphone paired with dual-channel noise cancellation and ENC+VoiceCore 2.0, which EMEET says eliminates up to 50dB of live and remote noise. There's a one-touch mute for privacy and anti-leakage technology so your audio doesn't spill into the room. It's Zoom certified with dedicated headset controls, which tells you exactly whose desk it's designed for.
Connectivity is where it pulls ahead for multitaskers. Bluetooth 5.3 plus a USB dongle enables seamless switching between two devices, and multipoint pairing keeps a laptop and a phone live at the same time. Latency is rated at 40ms, which matters for calls and video. Controls are touch-based, and EQ is adjustable through the EMEET TUNE app with no login required.
The open-ear air conduction design with soft silicone pads is meant to stay comfortable for long stretches, and a 16.2mm dynamic driver with spatial audio adds some depth to music and media. IPX5 water resistance covers sweat and splashes, and a 5-minute charge returns an hour of use. The catch: open-ear means you hear your surroundings, which is a plus in an office but a minus on a noisy train.
• Best for battery life → Sony WH-CH520. Up to 50 hours versus up to 20 hours talk / 40 hours playback on the EMEET.
• Best for calls and meetings → EMEET Airflow Open Ear. Detachable boom mic, one-touch mute and up to 50dB of noise cancellation are built for voice.
• Best for multipoint and device switching → EMEET Airflow Open Ear. Bluetooth 5.3 plus a USB dongle and two-device switching is a step beyond Sony's multipoint alone.
• Best for casual music and EQ tinkering → Sony WH-CH520. DSEE, 360 Reality Audio and app-based EQ are aimed at listeners.
• Best for noisy environments → EMEET Airflow Open Ear. Active noise cancellation beats Sony's passive on-ear isolation.
• Best for all-day comfort and lightweight wear → Sony WH-CH520. At 147g with an adjustable headband and soft earpads, it's built for long sessions.
• Best for workouts and sweaty commutes → EMEET Airflow Open Ear. IPX5 water resistance is a real advantage the Sony doesn't offer.
• Best for a wired fallback → neither. Both are wireless-only with no headphone jack.
If I had to pick one, I'd buy the EMEET Airflow Open Ear. In my opinion, Bluetooth 5.3 multipoint plus the USB dongle, the detachable boom mic and active noise cancellation make it the more capable tool if your day revolves around calls and switching between a laptop and a phone. I'd choose the Sony WH-CH520 instead if music is the priority and you want to charge roughly once a week rather than every couple of days — its 50-hour battery is the stronger single spec on this page. Either way, check the current price on Amazon before deciding, since that's the one variable these specs can't settle for you.
what is multipoint bluetooth headphones
Multipoint Bluetooth is a feature that lets one headphone hold an active connection to two devices at the same time, so you can take a call on your phone while staying linked to a laptop. Both the Sony WH-CH520 and the EMEET Airflow Open Ear support it.
can bluetooth headphones connect to multiple devices
Yes, if they support multipoint. The EMEET Airflow Open Ear adds a USB dongle on top of Bluetooth 5.3 for switching between two devices, while the Sony WH-CH520 relies on its multipoint connection with Bluetooth 5.2.
which headphones have bluetooth multipoint
Both models here do. The Sony WH-CH520 lists Multipoint Connection directly, and the EMEET Airflow Open Ear lists Multi-Point pairing alongside Bluetooth 5.3, so multi-device use isn't a deciding factor between these two.
do these headphones have noise cancelling
Only the EMEET Airflow Open Ear has active noise cancellation, rated to cut up to 50dB with ENC+VoiceCore 2.0. The Sony WH-CH520 has no active noise control — it relies on its on-ear fit and mic noise suppression for calls.
