How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight, everyday Bluetooth headphone with marathon battery life and app-based sound tuning, choose SONY WH-CH520; if you need a TV-first wireless headphone with a dedicated transmitter, low latency and wired inputs for older TVs, choose PROW Headphones.
• SONY WH-CH520 — biggest strength: up to 50 hours of battery life, multipoint pairing for two devices at once, and EQ customization through the Sony Headphones Connect app.
• SONY WH-CH520 — biggest trade-off: on-ear plastic build with no wired jack and no active noise cancellation, so it's a music-and-calls headphone, not a home-theater accessory.
• PROW Headphones — biggest strength: a bundled wireless transmitter plus optical, coaxial, AUX and Bluetooth TV connections, with 35 ms latency and five EQ presets for dialogue clarity.
• PROW Headphones — biggest trade-off: only around 20 hours per charge and a 3-hour charge time, and it's over-ear and heavier — a seated, TV-focused tool rather than a commute companion.
• Who each pick is for: SONY WH-CH520 is for people who live in Bluetooth all day — commuting, working, walking, taking calls. PROW Headphones is for someone who wants to watch TV late at night without waking the house, especially on a TV with optical or coaxial output.
The WH-CH520 is a Bluetooth 5.2 on-ear headphone with 20 Hz–20,000 Hz dynamic drivers, a built-in microphone and a plastic body that weighs 147 g. That weight matters more than it sounds. On-ear designs press against the ear rather than around it, and Sony pairs that with swivel earcups, an adjustable headband and soft ear pads — so the practical pitch is "slip them on, forget them, wear them for hours."
The headline number is battery: up to 50 hours per charge, with quick charging as a backup option. For anyone who has ever watched a headphone die mid-flight, that's the whole argument. There's also multipoint, so you can be connected to a laptop and a phone at the same time and jump between a call and a video without re-pairing. Calls run through the built-in mic, so you can take them without pulling your phone out.
Who should buy it: commuters, students, remote workers and anyone who wants one headphone for music, podcasts and calls across two devices, and who hates charging things. Who should skip it: anyone who needs active noise cancellation (there's none here), anyone who wants a wired fallback (there's no headphone jack), and anyone shopping specifically to upgrade their TV audio — that isn't what this is built for. Note this listing is a renewed unit with a 90-day limited warranty, which is shorter than a new retail warranty, so factor that in if long-term coverage matters to you.
PROW Headphones: Who It's For
The PROW Headphones are built around a different job entirely: television. The box includes a wireless transmitter plus RCA, 3.5 mm AUX, optical and coaxial cables and a Type-A to Type-C data cable, so the set works with TVs that output optical or coaxial audio, with TVs that only have AUX, and over straight Bluetooth as well. If your TV is old enough that "Bluetooth audio" isn't in its menu, that bundled transmitter is the difference between this working and not working.
The latency figure is the other reason it exists: 35 ms of audio latency, with a 2.4 GHz connection and a receiving range of up to 50 ft / 15 m. When audio and lip movement drift apart, TV watching becomes unbearable; a low-latency link is the fix, and it applies to both the 2.4 GHz mode and Bluetooth 5.4. There are also five EQ presets, and the built-in microphone is aimed at clear dialogue — which is exactly what people struggling with muddy TV speech want.
Physically it's an over-ear design with 40 mm dynamic drivers, 32 ohm impedance, 100 dB sensitivity and a 20 Hz–20 kHz range, built from ABS, leather, metal and plastic at 185 g. Over-ear cups surround the ear instead of pressing on it, and the headband adjusts for fit. Controls are physical push buttons rather than an app, which is the right call for a couch device — no phone needed to change a preset.
Who should buy it: late-night TV watchers, people in shared homes or apartments, anyone with mild hearing difficulty following dialogue, and anyone whose TV lacks modern Bluetooth. Who should skip it: frequent flyers and commuters. Twenty hours per charge and a 3-hour charge time is fine at home and annoying on the move, and there's no active noise cancellation here either — the spec sheet lists sound isolation, which is passive. The warranty is 6 months.
• Best for battery life → SONY WH-CH520 (up to 50 hours vs about 20).
• Best for TV watching → PROW Headphones (transmitter, optical/coaxial/AUX inputs, 35 ms latency, dialogue-focused EQ presets).
• Best for commuting and travel → SONY WH-CH520 (147 g, swivel earcups, multipoint for two devices).
• Best for older TVs without Bluetooth → PROW Headphones (the bundled transmitter and wired optical/coaxial/AUX connections).
• Best for customizing your music sound → SONY WH-CH520 (EQ Custom in the Sony app plus DSEE for compressed files).
• Best for physical controls without an app → PROW Headphones (push-button controls and five onboard EQ presets).
• Best for wired fallback → PROW Headphones (3.5 mm jack; the Sony has no jack at all).
• Best for all-day wear comfort → SONY WH-CH520 (lighter on-ear build with swivel cups), though over-ear fans may prefer the PROW's cup design.
• Best for phone calls → SONY WH-CH520 (built-in mic with multipoint switching between phone and computer).
In my opinion, most people searching these two names should buy the SONY WH-CH520. It covers the widest range of everyday situations — music, podcasts, calls, two devices, 50 hours away from a charger — and the app EQ gives you room to tune it to your taste. I'd only point you to the PROW Headphones if TV audio is the actual problem you're solving: the transmitter, the optical/coaxial/AUX inputs and the 35 ms low-latency link are things the Sony simply doesn't attempt. Buy the Sony for your ears on the move; buy the PROW for your ears on the couch. Check the current price on Amazon before deciding, since that's the one variable that can flip a close call either way.
FAQ
They work with Bluetooth TVs, with 2.4 GHz via the included transmitter, and with TVs that have optical, coaxial or AUX outputs via the bundled cables. If your TV has none of those outputs, neither mode will help.
The Sony is rated at up to 50 hours per charge; the PROW at about 20 hours with a 3-hour charge time. If you're away from a charger for days, the Sony wins clearly.
Neither one has active noise cancellation. The Sony's spec sheet lists no noise control, and the PROW lists sound isolation, which is passive blocking from the over-ear cups rather than electronic cancellation.
