How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a long-battery, app-tuneable on-ear pair built for all-day music and calls, choose Sony WH-CH520; if you need an open-ear, ear-canal-free design that keeps you aware of traffic and surroundings while you run or ride, choose QAZITV Bone Conduction Headphones.
• Sony WH-CH520 — biggest strength: up to 50 hours of battery life with a 3-minute quick charge that gives 1.5 hours of listening, plus Bluetooth multipoint so it holds two devices at once.
• Sony WH-CH520 — biggest trade-off: it's an on-ear, closed design with no active noise cancellation, so it physically sits on your ears rather than leaving them open to the world.
• QAZITV Bone Conduction Headphones — biggest strength: an open-ear, bone-conduction build that transmits sound through the temporal bone and never blocks the ear canal, so you stay aware of your surroundings.
• QAZITV Bone Conduction Headphones — biggest trade-off: a much shorter battery rating (10 hours average, 8 hours per the feature notes) and a bulkier boom-mic arm rather than a discreet everyday look.
• Who each is for: Sony for commuters, students and desk workers who want long listening sessions and multipoint convenience; QAZITV for runners, cyclists and outdoor workers who prioritize safety and hygiene over maximum playtime.
The WH-CH520 is, in my opinion, the more versatile everyday headphone of these two. Its headline number is battery: up to 50 hours average life, with a 3-hour full charge and a quick-charge function that gives you 1.5 hours of playback from just 3 minutes on the cable. That combination matters if you're the kind of person who forgets to charge — you can top it up on the way out the door and still get through a commute or a workout.
Where it earns its keep is connectivity and control. The WH-CH520 supports multipoint connection, so it can stay paired to two devices at once — your laptop and your phone, for example — and you switch between them without re-pairing every time. Add Swift Pair and Fast Pair for quick setup, on-earcup buttons for one-click call answering, and voice control, and it's clearly designed for people who take a lot of calls while moving between devices.
On sound, the Digital Sound Enhancement Engine (DSEE) is meant to restore high-frequency detail lost when music is compressed, and the Sony | Headphones Connect app lets you adjust EQ presets or build your own. It's also 360 Reality Audio certified, which uses an ear-shape analysis in the app for a more immersive mix. Physically it's a lightweight 147 g on-ear headphone with an adjustable headband and soft earpads, Bluetooth 5.2, a dynamic driver, and a 20 Hz–20,000 Hz range. There's no headphone jack and no active noise cancellation — noise control is listed as "None," though the built-in mic uses noise suppression processing for calls.
Buy it if you want the longest possible runtime, multipoint switching between two devices, and app-based sound tuning in a light, simple on-ear package. Skip it if you need to hear traffic and your surroundings, want a fully open ear canal, or need active noise cancellation on a plane or train.
The QAZITV set approaches listening from the opposite direction. Instead of covering your ears, it vibrates your temporal bone to send sound to the inner ear, leaving the ear canal completely open. That's the whole point of the design: your ears stay clean and hygienic, the eardrum isn't being pushed against by a sealed cup, and — crucially for outdoor use — you can still hear cars, bikes and people around you.
The fit follows from that. It's an open-ear ear-hook design in black plastic, and at 30 g it's remarkably light. The feature notes emphasize comfort over long wear with no pressure pain, which lines up with a hook that rests around the ear rather than clamping onto it. Controls are button-based — multi-function, power and volume — so you can manage calls, tracks and volume by feel without stopping what you're doing.
For calls, there's an adjustable noise-canceling boom microphone that you position toward your mouth; QAZITV says the dual ENC noise reduction filters ambient noise and lifts your voice. Battery is listed as 10 hours average life from a 2-hour charge, with the feature copy citing 8 hours of playtime per full charge — enough for a long run, a ride or a work shift, but nowhere near the Sony's 50.
Connectivity is the other strong suit: it's Bluetooth 5.2 with a 10-meter range, compatible with iPhone, Android and Windows computers, and it can connect to two devices simultaneously and switch between them without repeated pairing. In other words, it also does multipoint — just in a very different form factor.
Buy it if you run, cycle, commute on foot or work in a job where you must stay aware of your surroundings, and you want an ear-canal-free fit that stays comfortable for hours. Skip it if you want maximum battery, a discreet look, or a closed design that isolates you from background noise.
• Best for battery life → Sony WH-CH520. Up to 50 hours average versus 10 hours average on the QAZITV, plus a 3-minute quick charge worth 1.5 hours.
• Best for staying aware of traffic → QAZITV Bone Conduction Headphones. The open-ear bone-conduction design never covers or blocks the ear canal.
• Best for multipoint between two devices → both, but for different reasons. The Sony uses multipoint with Swift Pair/Fast Pair for laptop-plus-phone life; the QAZITV connects two devices simultaneously and switches without re-pairing.
• Best for all-day comfort in a light frame → QAZITV. At 30 g with an open ear-hook, it's the lighter of the two on paper (the Sony is 147 g).
• Best for sound customization → Sony WH-CH520. DSEE restoration, EQ presets in the Sony | Headphones Connect app, and 360 Reality Audio certification.
• Best for calls in a noisy outdoors setting → QAZITV. The adjustable boom mic plus dual ENC noise reduction is built specifically to lift your voice over ambient noise.
• Best for ear hygiene and an open canal → QAZITV. Sound bypasses the ear canal entirely.
• Best for a simple, closed on-ear listen → Sony WH-CH520. Dynamic driver, 20 Hz–20,000 Hz, on-ear earpads, Bluetooth 5.2.
If I had to pick one for most people, I'd buy the Sony WH-CH520. The 50-hour battery, quick charge and app-tuned sound make it the better all-rounder for commuting, studying, working and taking calls, and multipoint keeps it glued to both your laptop and phone. I'd only steer you to the QAZITV Bone Conduction Headphones if your priority is running, cycling or outdoor work where hearing your surroundings is non-negotiable — and where an open, ear-canal-free fit matters more than runtime. In my opinion, the Sony wins on endurance and sound control; the QAZITV wins on safety, hygiene and lightweight comfort.
