If you want a music-first wireless headphone with marathon battery life and app-tuned sound, choose SONY WH-CH520; if you need open-ear awareness for running, cycling and workouts, choose Ogogrs Bone Conduction Headphones.
• SONY WH-CH520 biggest strength: up to 50 hours of battery, USB Type-C quick charging, EQ Custom in the Sony | Headphones Connect App, DSEE upscaling and multipoint pairing with two devices.
• SONY WH-CH520 biggest trade-off: it's on-ear and fully sealed over your ears, so there's no noise cancelling and no ambient awareness — you're tuned out of your surroundings.
• Ogogrs Bone Conduction Headphones biggest strength: open-ear bone conduction design with a bendable titanium frame, IP55 water resistance and Bluetooth 5.3, so your ears stay free and you stay aware.
• Ogogrs Bone Conduction Headphones biggest trade-off: battery tops out around 10 hours, and bone conduction sound is a different listening experience than a traditional driver pressed against your ear.
• Who SONY WH-CH520 is for: commuters, students, podcast listeners and anyone who wants one pair for music, calls and long days away from a charger.
• Who Ogogrs is for: runners, cyclists, hikers and gym-goers who want audio without blocking out traffic, teammates or the trail.
The WH-CH520 is built around one idea: keep the music going and don't make you think about it. Sony rates the battery at up to 50 hours, and quick charging via USB Type-C gives you playback from a very short top-up — the kind of thing that saves you when you realize your headphones are dead five minutes before a flight. For a music-first buyer, that number is the headline. It's not "good enough for a day." It's multi-day road trip territory.
Sound customization is where this model separates itself from generic budget wireless headphones. The Sony | Headphones Connect App includes EQ Custom, so you can pick presets that suit a genre or build and save your own. DSEE is also on board to boost compressed music files, which matters if you stream from a service that compresses heavily. The drivers are 12 mm dynamic units with a 20 Hz–20,000 Hz frequency range and 32 ohm impedance, and Bluetooth 5.2 covers roughly 10 meters of range. There's a built-in microphone for hands-free calls, multipoint connection so you can jump between a laptop and a phone, and voice assistant support through "OK Google" or "Hey Siri." You can also locate lost headphones by sound or last known location through Google's Find My Device app.
Comfort is clearly the other priority. At 147 g with soft ear pads, a head cushion, silent joints and swivel earcups, the WH-CH520 is designed for all-day wear and easy packing. It's available in six colors, which is a small thing until you realize you'll be wearing these in public constantly.
Who should buy it: anyone whose primary use is music, podcasts, audiobooks and calls in relatively controlled environments — commuting, studying, working, traveling. Who should skip it: if you need to hear traffic while running, if you want active noise cancelling to silence a plane cabin, or if you want earbuds you can sweat heavily in. This is an on-ear, plastic-bodied, non-waterproof headphone with no noise cancelling. That's a deliberate trade, not a flaw.
Ogogrs takes the opposite approach. Instead of sealing sound in, these headphones sit on your temples and transmit audio through bone conduction, leaving your ear canals completely open. That single design choice defines everything about them. You hear your music and you hear the world at the same time — the brand frames this as a safety advantage over traditional earplugs or earmuff-style headphones, and for runners and cyclists on open roads, that reasoning is sound.
The build is aimed squarely at movement. The frame is titanium, lightweight and flexible — the brand says it can be bent freely and stays stable during high-intensity training. Earpiece shape is described as temple-fit, so it hooks around rather than pressing in. Water resistance is rated IP55, which covers sweat, rain and the kind of spray you'd get on a ride or a hike. Bluetooth 5.3 handles the connection with a stated range of 33 feet, and there's a built-in microphone for calls, including remote video conferences.
Battery is the honest limitation. Ogogrs states up to 10 hours of music or calls, with Type-C fast charging. That's a full week of workouts for most people, but it's a fifth of what the Sony offers. If you're the type who charges once and forgets for a week, this will require more attention.
Who should buy it: runners, walkers, cyclists, hikers, gym-goers and anyone who wants music during sport without sacrificing awareness. It also suits people who find in-ear or on-ear pressure uncomfortable over long sessions. Who should skip it: anyone chasing deep, immersive, bass-heavy music listening in a quiet room. Bone conduction with a 100 ohm impedance bone conduction driver delivers audio in a fundamentally different way than a dynamic driver, and the open-ear design means background noise competes with your music. In my opinion, this is a fitness and safety product first, a music product second.
Side-by-Side: Which Should You Choose?
• Best for battery life → SONY WH-CH520. Up to 50 hours versus up to 10 hours. It's not close.
• Best for music quality and tuning → SONY WH-CH520. EQ Custom in the app, DSEE upscaling and a 12 mm dynamic driver give you more control over how music sounds.
• Best for staying aware of your surroundings → Ogogrs. Open-ear bone conduction lets traffic, people and ambient sound through by design.
• Best for calls and multitasking → SONY WH-CH520. Multipoint pairing with two devices at once plus a built-in mic makes switching from a laptop video to a phone call seamless.
• Best for all-day comfort at a desk → SONY WH-CH520. 147 g, swivel earcups, adjustable headband and a head cushion are aimed at long wear.
• Best for travel and packing → SONY WH-CH520. The swivel design folds compact, and 50 hours means you can leave the cable at home.
• Best for hot, sweaty or rainy conditions → Ogogrs. The Sony has no water-resistance rating, so keep it out of the rain and off the treadmill.
If music is the point, I'd buy the SONY WH-CH520. Fifty hours of battery, app-based EQ, DSEE, multipoint and a comfortable 147 g on-ear build make it the more versatile headphone for the way most people actually listen — commuting, working, traveling and calling. The Ogogrs is the better tool for a narrower job: sport, where open-ear awareness and IP55 water resistance genuinely matter and battery life is secondary. Buy the Sony for listening. Buy the Ogogrs for moving. If you do both regularly, they're complementary rather than competing, and the deciding factor should be whichever activity fills more of your week. Check the current price on Amazon before you commit, since that's the one variable I can't weigh for you.
how to make headphones music louder
Start with your source device — most phones and laptops have their own volume ceiling, and some apply a volume limit you can disable in settings. On the SONY WH-CH520, the EQ Custom feature in the Sony | Headphones Connect App lets you adjust the sound profile, and DSEE boosts compressed music files, both of which affect perceived loudness and clarity. The Ogogrs relies on its bone conduction driver and its own volume controls, but remember that open-ear audio competes with ambient noise, so a quieter environment always helps.
how to fix stereo headphones
Basic troubleshooting applies to both: confirm the headphones are charged, since a low battery is the most common cause of dropouts or one-sided sound. Then check the Bluetooth pairing — both models use wireless Bluetooth only, with no headphone jack, so a faulty or unstable connection is the usual culprit. Toggling Bluetooth off and on, forgetting and re-pairing the device, or restarting the source usually resolves it. If one side is genuinely silent after that, it's a hardware issue rather than a settings one.
how to test stereo headphones
Play a track you know well and listen for balanced output on both sides. With the SONY WH-CH520, you can also open the Sony | Headphones Connect App and check the EQ Custom settings to confirm nothing is skewed to one channel. For the Ogogrs, test the temple-fit placement — bone conduction depends on the transducers sitting correctly against your cheekbones, so a slight reposition can change what you hear. Also walk a few meters away to confirm the Bluetooth range holds, which is roughly 10 meters on the Sony and 33 feet on the Ogogrs.
how to make stereo headphones
You can't build a proper stereo pair from these — both are single wireless units with their own drivers, and neither is designed to be assembled or split into separate left and right pieces. What you can do is pair the SONY WH-CH520 with two devices at once via multipoint, which is the closest thing to a "dual" setup either model offers. For the Ogogrs, stay within the 33-foot Bluetooth range and keep the temple-fit transducers positioned consistently for the most stable stereo image.
