A lightweight pair of headphones for music, podcasts, online meetings and travel may seem easy to choose. However, small differences in product information can have significant consequences. With the Sony WH-CH520 wireless headphones, there are three points in particular that you should check before buying: the actual battery life, the Bluetooth version and the difference between on-ear and over-ear headphones.
The WH-CH520 is a pair of wireless on-ear headphones with a microphone, USB-C connection and multipoint connectivity. This makes the model appealing for everyday use, but it is not automatically suitable for every situation. Below, you can read what to look out for and which version best suits your needs.
The product description refers to the Sony WH-CH520 as headphones with 50 hours of battery life. However, the technical product specifications also state a battery life of 40 hours. Such differences can arise from different testing methods or product listings.
Therefore, check the following before buying:
The description also mentions fast charging: according to the product information, 3 minutes of charging provides approximately 1.5 hours of use. Treat this as a stated guideline rather than a guaranteed usage time in every situation.
The Sony WH-CH520 is described in the product specifications as Bluetooth 5.2 headphones. Some descriptive text states Bluetooth 5.0. For everyday use, the most important factors are whether your phone, tablet or laptop is compatible and whether the connection remains stable within the normal range.
When comparing models, do not look only at the version number. Also check:
The WH-CH520 has an on-ear design. The ear cushions therefore rest on your ears rather than completely surrounding them. This usually results in a compact, lightweight model, but it may provide less isolation on a busy train or in the office than over-ear headphones with active noise cancellation.
The stated features include:
A closed-back housing does not mean that surrounding noise disappears completely. If you are looking for maximum sound isolation or noise cancellation, a different type may be more suitable.
The adjustable headband and soft ear cushions are designed for extended use. The low weight is practical when carrying the headphones in a bag or using them during your commute. However, check whether the on-ear fit remains comfortable around your ears. Headphones may be lightweight on paper but still feel tight if the headband or cushions do not fit properly.
The Sony WH-CH520 is a pair of Sony headphones with a microphone. This allows you to make phone calls and take part in online meetings without removing your headphones. Call quality in practice may depend on your surroundings, the laptop or smartphone you use and the software provided by the meeting service.
A key practical advantage is the multipoint connection. According to the product information, you can connect the headphones to, for example, a smartphone and laptop at the same time and switch between the two devices.
This works well in the following situations:
The exact controls may vary depending on the device. After pairing, check that both devices are visible in the Bluetooth settings.
The product description mentions Sony DSEE for tailored sound reproduction and support for the Sony Headphones Connect app. According to Sony’s own information, the app can help you adjust sound settings. This does not guarantee that every user will hear the same result; the type of music, source file and personal preference all play a part.
Why it suits this profile: Compact blue on-ear headphones for music, podcasts, phone calls and everyday travel, without features you may not use.
The product specifications clearly state the 147-gram weight, USB-C charging, a microphone and multipoint connectivity. However, check the stated battery life, as the product information mentions both 40 and up to 50 hours.
147 grams, Bluetooth, microphone, multipoint connectivity, USB-C and an adjustable headband.
Why it suits this profile: For those who value extra features, a long stated playback time and a sturdier design over the lowest possible weight.
The product specification lists Bluetooth 5.3, multipoint, USB-C and a foldable design. The model is not water-resistant, so do not assume it is suitable for use in wet conditions.
Stated playback time of more than 100 hours, Bluetooth 5.3, multipoint and wireless charging according to the product description.
Why it suits this profile: For travel and everyday use where active noise cancellation, over-ear comfort and multipoint matter more than an exceptionally low weight.
The listing distinguishes between a battery life of up to 50 hours without noise cancellation and 30 hours with noise cancellation. This is clearer than making one general battery claim.
Over-ear design, active noise cancellation, multipoint, microphone and USB-C according to the product specifications.
