The Quick Verdict
The Sony WH-CH520 is a no-nonsense, budget on-ear headphone that trades fancy features for raw practicality. With 50 hours of battery life, a lightweight build, and Sony's signature sound tuning, it's one of the best value picks under ₹5,000. It won't wow audiophiles or frequent travelers, but for everyday listening, online classes, and office work, it's a safe, reliable choice from a trusted brand.
The Good
1. Insane Battery Life — 50 Hours
This is the WH-CH520's killer feature. At up to 50 hours of continuous playback, you can go weeks without charging. Even at higher volumes (~70%), real-world usage delivers 40+ hours easily. The 3-minute quick charge for 1.5 hours of playback is a lifesaver for forgetful chargers.
2. Sony Sound Signature + App EQ
Out of the box, the sound is balanced and consumer-friendly — boosted lows, smooth mids, and non-harsh highs. The Sony Sound Connect app unlocks a 5-band EQ and DSEE (Digital Sound Enhancement Engine), letting you tailor the sound to your taste. For the price, the app integration is unrivaled.
3. Multipoint Bluetooth 5.2
Connect to two devices simultaneously — say, your laptop and phone — and switch seamlessly. This is a feature usually reserved for headphones double the price. Bluetooth 5.2 ensures stable connectivity up to 10 meters.
4. Lightweight and Comfortable
At just 147g, these are among the lightest on-ear headphones you can buy. The clamping force is gentle, and the padded earcups are comfortable for 2–3 hour sessions. The swivel design makes them easy to slip on and off.
5. Decent Build for the Price
The textured plastic doesn't feel premium, but it doesn't feel cheap either. Reddit users note the newer models have improved build quality over earlier batches, with no rattling issues. For ~₹4,000, the construction is solid.
6. Clear Calls for the Price
The built-in mic with noise suppression handles indoor calls and online classes well. Voices sound natural in quiet environments, though outdoor performance is average.
The Bad
1. On-Ear Design = Heat and Fatigue
The earpads are small and rest on your ears, not around them. After about an hour, your ears get warm and slightly fatigued. The pleather material doesn't breathe well. If you have larger ears or wear glasses, comfort drops faster.
2. No Active Noise Cancellation
There's no ANC — only passive isolation from the earpads. In noisy environments (metro, flights, busy streets), you'll hear everything. The "loudness cancels noise" argument only works at unsafe volumes.
3. Sound Leakage
Because they're on-ear with moderate clamping, sound leaks out at volumes above 60%. Not ideal for libraries or shared workspaces.
4. No Wired Option
There's no 3.5mm jack — if the battery dies, you're done. For a headphone marketed for long battery life, this is an odd omission.
5. Mids Can Sound Veiled
While the bass is punchy and treble is smooth, the midrange (vocals, guitars) lacks presence out of the box. You'll need the EQ app to lift the mids for a more engaging sound. Classical and vocal-heavy tracks suffer without tweaking.
6. Not for Sports or Commutes
The loose fit and on-ear design mean they slip during brisk walking or workouts. No IP rating either — sweat at your own risk.
