If you want long battery life and an on-ear design for study, choose Sony WH-CH520L; if you need open ears to stay aware of your surroundings, choose DOOGEEEco Bone Beat Run. For most desk-based study, I’d pick the Sony: its up-to-50-hour battery life and adjustable sound are better suited to long stretches of listening. The DOOGEEEco is the clearer choice for outdoor exercise, where hearing nearby sounds matters.
• Sony WH-CH520L: On-ear headphones with up to 50 hours of battery life, multipoint Bluetooth, and app-based EQ; the trade-off is that its on-ear design does not leave your ears open to surrounding sounds.
• DOOGEEEco Bone Beat Run: Open-ear bone-conduction design, IP66 protection against sweat and water, and up to 10 hours of playback; the trade-off is shorter battery life and no noise control.
• For study: Choose Sony if you want a more conventional headphone setup and long battery life. Choose DOOGEEEco if you need to keep your ears open to the room.
• For outdoor activity: DOOGEEEco is the more purpose-built option, with open-ear listening, water resistance, and physical controls.
• For switching between devices: Both support connecting to two devices, though the Sony describes Bluetooth multipoint while DOOGEEEco specifies simultaneous dual-device connection.
The Sony WH-CH520L is an on-ear Bluetooth headphone with an adjustable headband, soft ear pads, and up to 50 hours of battery life. For someone studying at a desk, that combination makes sense: you can keep a familiar headphone fit on for a long session without needing to recharge after every day of use. If the battery is low, Sony says a three-minute quick charge provides 1.5 hours of listening.
It also has Bluetooth multipoint, button controls, voice control, and sound adjustments through the Sony Headphones Connect app. The built-in microphone supports calls, and the stated noise cancelling is for reducing ambient noise during conversations. That should not be mistaken for a claim that the headphones actively cancel study-room noise during listening. If you need to hear people around you clearly, the on-ear design may still let in some surrounding sound, but it is not an open-ear design.

I’d consider the Sony for library or home study, everyday music, and calls, especially if battery life is high on your list. I’d skip it if your main need is to keep your ears unobstructed while running or cycling, or if you specifically want open-ear headphones. It offers sound isolation as a noise-control feature, not the DOOGEEEco’s open-ear approach.
The DOOGEEEco Bone Beat Run uses a bone-conduction driver and an open-ear structure. It does not plug the ear canals, so the design is intended to let you hear ambient sounds while listening. That is useful for running, cycling, and outdoor training when awareness of nearby traffic and other sounds matters. For study, it could suit someone who wants to hear a conversation or household activity without taking headphones off.
The DOOGEEEco offers up to 10 hours of continuous playback at 75% volume, with a five-minute charge said to add two hours of music. It supports Bluetooth 5.4 and connection to two Bluetooth devices at once. Physical buttons handle functions such as calls and track changes. Its IP66 rating is specified for sweat, rain, and splashes, making it more suited to workouts than a conventional on-ear headphone.
The main trade-off for desk study is that the open-ear design does not provide noise control. If you need to shut out distractions while reading or working, this is not the one I’d choose. Its battery life is also much shorter than the Sony’s stated maximum. I’d pick it when awareness, sweat resistance, and outdoor use matter more than long playback between charges.
• Best for long study sessions between charges → Sony WH-CH520L. It offers up to 50 hours, compared with up to 10 hours for the DOOGEEEco.
• Best for keeping your ears open to nearby sounds → DOOGEEEco Bone Beat Run. Its open-ear bone-conduction design is made to let ambient sounds remain audible.
• Best for outdoor exercise in sweat or light rain → DOOGEEEco Bone Beat Run. Its IP66 protection and open-ear design fit that use better than the Sony’s listed features.
• Best for adjusting sound through an app → Sony WH-CH520L. Its sound can be adjusted with EQ settings in the Sony Headphones Connect app.
• Best for two-device Bluetooth use → Either, with a slight difference in how the feature is described. Sony lists multipoint; DOOGEEEco says it supports simultaneous connection to two Bluetooth devices.
• Best for quick recovery from a low battery → Consider your listening pattern. Sony’s three-minute charge is stated to provide 1.5 hours of listening; DOOGEEEco’s five-minute charge is stated to provide two hours.
• Best for calls with physical controls → Both have useful call features. Sony offers call controls on the ear cups and a built-in microphone; DOOGEEEco includes physical buttons for answering calls.
• Best for a conventional on-ear headphone fit → Sony WH-CH520L. If you prefer a design that rests on your ears rather than an open-ear bone-conduction style, Sony is the more natural match.
For focused study in a quiet setting, I’d lean toward the Sony’s longer battery life and adjustable EQ. For studying while remaining alert to people nearby, the DOOGEEEco’s open-ear design is the more relevant feature. The right choice comes down less to a generic “sound quality” claim and more to whether you want a conventional on-ear fit or open ears.
My Verdict
I’d choose the Sony WH-CH520L for study because its up-to-50-hour battery life and app-based EQ suit long listening sessions better on paper. It also has multipoint Bluetooth and a familiar on-ear design. The DOOGEEEco is my pick for outdoor training, sweat resistance, and staying aware of surrounding sounds. For my study-focused recommendation, Sony is the better fit; I’d switch to DOOGEEEco only if open-ear awareness were the priority.
For long study sessions, the Sony has the advantage in stated battery life: up to 50 hours versus up to 10 hours for DOOGEEEco. The DOOGEEEco may suit study in a shared space if you want to hear surrounding sounds, but it has no listed noise control.
Sony lists noise cancelling for reducing ambient noise during calls, along with sound isolation as its noise-control feature. DOOGEEEco lists no noise control, and its open-ear design is intended to keep environmental sounds audible.
Which is better for running or cycling?
Yes. Sony lists Bluetooth multipoint, and DOOGEEEco says it can connect to two Bluetooth devices simultaneously. Both list a Bluetooth range of 10 meters.
• Panasonic ErgoFit Earbud Headphones vs ADADPU Headset
• MINDRESY Silicone Case Cover vs Echoes Rainbow Active Noise Cancelling
