The WH-CH520 boasts an ultra-lightweight build with swivel earcups, making it easy to wear over long periods.

The comfort level can be subjective; however, if you value a lightweight feel, the Sony WH-CH520 may be the better choice, but if you prefer a more secure fit, the Beats Solo 4 stands out.
Sound Quality
When it comes to sound quality, the Beats Solo 4 is engineered with custom acoustic architecture and updated drivers for a powerful audio experience. It also includes Personalized Spatial Audio with dynamic head tracking for immersive listening. Meanwhile, the Sony WH-CH520 offers customizable sound quality through the Sony | Headphones Connect App, allowing users to adjust EQ settings to their liking. Both headphones promise great audio, but the Beats Solo 4’s focus on high-fidelity sound may appeal more to audiophiles, while the Sony WH-CH520 could be better for those who enjoy personalizing their sound.
Battery Life
Both headphones offer an impressive battery life of up to 50 hours, but their charging capabilities differ. The Beats Solo 4 features Fast Fuel technology, allowing for a quick 10-minute charge that provides up to 5 hours of playback. In comparison, the Sony WH-CH520 can achieve up to 1.5 hours of playback with just a 3-minute quick charge. While both models excel in battery longevity, the Beats Solo 4 offers a slightly more extensive fast-charging feature, which can be crucial for users on the go.
Connectivity
The Beats Solo 4 features industry-leading Class 1 Bluetooth for an extended range and fewer dropouts, which can enhance the listening experience. It also supports quick pairing for both iOS and Android devices, making it versatile for users with different smartphones. On the other hand, the Sony WH-CH520 allows for multipoint connection, letting users switch between two devices seamlessly. This feature is particularly advantageous for those who frequently switch between devices, such as a phone and a laptop, making the Sony WH-CH520 a strong contender for multi-device users.
Additional Features
The Beats Solo 4 comes with high-quality call performance and voice assistant interaction through its built-in microphone, enhancing its usability for calls and smart features. The Sony WH-CH520 also includes a built-in microphone for hands-free calling and boasts additional features like DSEE technology to boost the quality of compressed music files, as well as the ability to find lost headphones using Google’s Find My Device app. Both headphones provide valuable additional features, but the Beats Solo 4 may have the edge in call quality and smart integration.
Price and Value
In terms of price, the Beats Solo 4 retails for $129.95, while the Sony WH-CH520 is significantly cheaper at $54.00, making it about 58% less expensive. Despite the price difference, both headphones offer up to 50 hours of battery life and competitive sound quality. For budget-conscious consumers, the Sony WH-CH520 provides excellent value for the features it offers, while the Beats Solo 4 may justify its higher price with superior sound quality and design, appealing to a more premium market.
Market Performance
The Beats Solo 4 holds a strong position in the market, with a sales rank of 28, indicating its popularity among consumers. The Sony WH-CH520, with a sales rank of 197, is also performing well but does not match the same level of demand. This difference in sales rank may reflect the brand's reputation and perceived quality, with Beats often seen as a premium brand. However, the Sony WH-CH520's lower price point may attract budget-conscious consumers, potentially increasing its market presence over time.
Which should you buy?
Choosing between the Beats Solo 4 and the Sony WH-CH520 ultimately depends on your priorities. If you prioritize high-fidelity sound, a snug fit, and premium features, the Beats Solo 4 is the way to go. However, if you’re looking for a more affordable option with solid performance, lightweight design, and useful features for everyday use, the Sony WH-CH520 is an excellent choice.
