Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Though now owned by Apple, the headphones are often powered by a custom Beats chip rather than Apple's H or W series, and frequently offer feature parity for both Android and Apple devices (with some exceptions).

- Spatial audio with head tracking is supported exclusively for Apple users, creating a more immersive listening experience while viewing compatible video content.

- Good noise canceling performance
- Works well on both iOS and Android
- Comfortable and easy to fold down to a very compact size, allowing for easy portability
- Offers more balance, while still providing the crisp upper register and hefty bass that Beats is known for

- The plastic exterior doesn't always feel premium
- Tight clamping force and the ear cups are barely big enough to fit ears, making it a little hard to wear the Beat Studio Pro for more than a few hours
- Can slip out of place with intense movements
- Lack of ear detection means the Studio Pros won't automatically pause when removed, or resume when put back on
Comparisons (according to reviewers)

- The Sony WH-1000XM5 arguably has better ANC performance
- The Bose QC45 suits heads and ears much more comfortably
- The Sony WH-1000XM5 comes across as slightly more open and natural sounding—accurate is a word you could also substitute for natural
- There is very little that the Beats Studio Pro does better than the Sennheiser MOMENTUM 4 Wireless for the same price
- The Studio Pros have much better value for money than the Apple AirPods Max
Takeaway: The Beats Studio Pro is a great pair of mid-tier headphones for people who want good active noise cancellation, good sound quality, and cross-platform functionality. The convenient design makes them ideal for portability and everyday use.

Our take on the brand
Our Summary
Product Strengths
- High-end design with premium materials (cloth and aluminum construction, aluminum accent rings, soft faux leather, stitch-free Nappa leather) gives a luxury vehicle feel and understated style

- Integration with the Bowers & Wilkins Music app allows customization of noise canceling levels, ambient pass-through, and EQ tone control
- Improved clarity of voice on phone calls is due to the redesigned microphone pattern
