• Sony WH-CH520L — biggest strength: up to 50 hours of playback with a quick-charge function, plus Bluetooth 5.2 multipoint and DSEE sound enhancement with EQ in the Sony Headphones Connect app.
• Sony WH-CH520L — biggest trade-off: it's an on-ear design that sits over your ears, so it isolates sound and blocks some of your surroundings, and it weighs 310 g.
• LC-dolida Open-Ear — biggest strength: the smart LED display case acts as a control hub for volume, EQ, music, timers, camera and Find My Earbuds — no app required — with up to 30 hours of battery.
• LC-dolida Open-Ear — biggest trade-off: open-ear earbuds don't seal your ear canal, so bass and isolation are naturally lighter than a closed on-ear fit, and noise control is listed as none.
• Sony WH-CH520L is for: long listening sessions, commutes and desk work where you want rich sound and almost never want to think about charging.
• LC-dolida Open-Ear is for: runners, cyclists and anyone who needs to hear traffic and people around them while listening.
The WH-CH520L is built around stamina and convenience. Sony rates it at up to 50 hours of battery life, and when it does run low, a quick charge gives you 1.5 hours of listening from a 3-minute top-up. For anyone who charges headphones on a Sunday and expects them to survive the week, that's the whole pitch in one number. You also get Bluetooth 5.2 with multipoint, Swift Pair and Fast Pair, so switching between a laptop and a phone is quick, and a 10-metre Bluetooth range covers moving around a room without dropping the signal.
Buy it if: you want one pair of headphones for work, travel and long music sessions, and you'd rather control sound through an app than fiddle with a case.
Skip it if: you need to stay aware of your surroundings — the on-ear design and sound isolation work against that — or you want earbuds that disappear into a pocket.
LC-dolida Open-Ear: Who It's For
LC-dolida takes the opposite approach. These are clip-on open-ear earbuds, which means they rest outside your ear instead of sealing it. The result is pressure-free comfort with no ear-canal fatigue, and — more importantly for a lot of people — full situational awareness. You hear traffic, cyclists, colleagues and announcements while your music keeps playing. That single design choice is why this pair makes sense for running, walking, cycling and commuting, and why the secure clip-on fit matters: the earbuds are held in place during movement rather than relying on a seal.
The standout feature is the smart LED display case. It works as a control hub: check battery and time, adjust volume, switch EQ modes, control music, set a timer, trigger your phone's camera, and use the Find My Earbuds function to locate a misplaced bud. No app, no downloads, no permissions. For anyone who's tired of hunting through Bluetooth settings menus, that's genuinely refreshing. The earbuds use Bluetooth 5, silicone construction, and a 20 Hz – 20,000 Hz frequency range, with up to 30 hours of battery life and about an hour to charge the case.
Buy it if: you want awareness over isolation, you hate app-dependent earbuds, and you like the idea of controlling everything from the case.
Skip it if: you want deep, sealed bass or strong noise blocking — the open design and the "noise control: none" spec mean you'll hear the world, for better and worse.
Side-by-Side: Which Should You Choose?
• Best for battery life → Sony WH-CH520L. Up to 50 hours versus up to 30 hours, and the quick-charge feature is a real safety net.
• Best for all-day comfort in one position → LC-dolida Open-Ear. Pressure-free and no ear-canal fatigue, which suits marathon listening sessions.
• Best for immersive music and calls → Sony WH-CH520L. DSEE, EQ in the app, and a microphone with noise cancelling for clearer conversations.
• Best for app-free control → LC-dolida Open-Ear. Volume, EQ, music, timers, camera and Find My Earbuds all live on the LED display case.
• Best for workouts and cycling → LC-dolida Open-Ear. Clip-on secure fit and open ears are built for movement.
• Best for desk work and travel → Sony WH-CH520L. Multipoint, Swift Pair and Fast Pair make it easy to hop between devices.
• Best for losing your earbuds → LC-dolida Open-Ear. The Find My Earbuds function on the case is a small feature you'll appreciate the day you need it.
In my opinion, the LC-dolida Open-Ear is the more interesting buy for 2026, because the smart LED case and open-ear awareness solve problems most earbuds ignore — and if you run, cycle or work around people, that matters more than a bigger battery number. That said, if your priority is sound quality, long sessions and never thinking about charging, I'd take the Sony WH-CH520L. My honest pick for most people: choose based on whether you want to hear the world or shut it out.
